Researchers develop fire-safe lithium-ion batteries

A team of researchers at the Fraunhofer Institute for Silicate Research (ISC) is working on a non-flammable lithium-ion Dell Latitude E6400 battery. Unlike conventional power saving, the new development is based on a solid electrolyte and therefore is not flammable.

In the material that is used by a team led by Kai-Christian Miller, there is a plastic (polymer) from the group of substances called ormocers. These are compounds with silicon-oxygen chains that form an inorganic structure, depend on the organic side chains. Continue to allow the flow of current lithium-ion.

"We have succeeded in replacing the inflammable organic electrolytes with a non-combustible, dimensionally stable polymer," says Miller. As a result, the safety of lithium-ion Dell Inspiron 1720 battery improve significantly. In addition, the electrolyte can not leak out of a solid substance. "Typically, decreases the conductivity of a polymer, the harder it is, we had numerous parameters, we could adjust -.. For example, we use coupling elements with two, three or four arms"

Lithium-ion batteries are widely used as an energy supplier and are used in almost all mobile devices like cell phones and laptops. For the current memory speaks their high energy density and the lack of memory effect, the other battery types exhibit. However, the products prove to be problematic for their safety. This problem was the industry well known, but was accepted.

The public was the danger of fire in late 2006 was a series of recalls of well-known PC manufacturers out drastically. "The main problem with lithium-ion Dell Inspiron 1545 battery, the lithium," then said the battery expert Rolf Zinniker of the ETH Zurich. Lithium is very unstable and react to water with evolution of hydrogen very aggressive.

At the Hanover Fair presented by researchers at the ISC the first prototype of its rechargeable Dell Inspiron 1520 battery development. Indeed until the product in cell phones, PDAs, laptops or cordless drills are used, however, would take several years, the researchers said. Currently needed in particular the conductivity of the energy storage can be further improved. In about five years, will the performance of the new Dell Inspiron 1525 battery technology, however, nearly correspond to the current products, says Moeller.

Four errors in laptop batteries maintenance

Misunderstanding one: notebook bought three times the need to repeatedly charged and discharged in order to activate the battery.

If you buy a notebook that is more than a year of inventory or do not need to pretend that the current batteries in the Dell Inspiron 1545 battery when the work has been activated, and the batteries in the package in a notebook battery, equivalent to some time to activation of the test, so you get the hands of batteries, which have already been activated, and again three charge-discharge process was unnecessary to increase battery depletion.

Misunderstanding two: the first charge must be sufficiently free of charge for 12 hours

This early, which is not applicable on the DELL Latitude D830 Battery control circuit of nickel-hydrogen batteries model, but now has a smart charge and discharge control circuit for the notebook battery is a joke, if the laptop battery is fully charged, the charging current is automatically cut off, even if you charge for 120 hours, state and there will be no further changes, in general, even the slowest machine charge, six hours completely filled, the remaining “charge” is just a waste of time. It’s time to get new machines should be first Battery.

Misunderstanding three: the need for regular calibration of battery once a month put the entire load.

Strong memory effect in nickel-hydrogen batteries, which is an essential task, but also for Li-ion battery, the cycle is too frequent, and lithium batteries not completely eliminate the memory effect, but was greatly reduced memory effect when the Dell Inspiron N4110 Battery is frequently, you should drain the battery, the relatively low (about 10 ~ 15%) battery, but even if the discharge is not open Machines (0 ~ 1%), belong to the lithium batteries have a greater depth of injury discharge, generally every two months, not that kind of operation, once it. If you seldom use batteries, is every 3 months to such an operation as long to perform.

Misunderstanding four: correction can improve battery life

The so-called correction, if the actual capacity of the Dell Inspiron M5030 battery and control circuit capacity is not the same record, the depth of a single battery charge and discharge operation, so that control close track record so to the actual situation of the battery, this is a true performance of the battery capacity operation instead, the capacity of key factors to improve here, the actual capacity of the Dell Inspiron Mini 9 battery when the actual capacity can increase the battery control circuit as the capacity to record levels, correction of the capacity of the battery looks like when the battery’s actual capacity than the control circuit capacity reduce to a record low, the correction of the capacity of the battery looks like, why discuss many people, the reasons for the effect of correction, keep in mind that the correction to make in themselves, the actual capacity of the battery by removing the DELL XPS M1530 battery and control circuit between bias is shown, as shown, increase or decrease capacity, this is the status of the battery itself, rather than determine your prescription. A correction is likely because the battery discharge when the depth of the injury, but a significant reduction in capacity.

The researchers developed 10-fold increase in battery life fluoride

Contour Energy Systems with CalTech and CNRS (French Scientific Research Center) on 17 March 2010 announced the formation of partnerships developed lithium-ion energy storage Dell Inspiron 6400 battery with a new fluorine-chemistry, nano-materials research and manufacturing processes.

Fluorocarbon DELL XPS M1530 battery since the 1970s introduced, which is characterized by a high energy density, high temperature resistance and long life, but the limited storage capacity and poor performance at low temperatures. Contour Energy Systems has developed a proprietary process, the introduction of carbon fluoride materials developed, compared with traditional fluorocarbon materials with different atomic structure fundamental to these restrictions.

4 different types of DELL Latitude D630 battery weight and volume energy density

High Energy Batteries: Germany must follow suit

All points have been set: The production of lithium-ion Dell Vostro 1710 battery for electric cars promises the industry for years to come a billion dollar business. In other industrialized nations has already set out in the U.S. and create concrete plans and new factories already hard facts, while Germany still dismayed at the head scratching. State subsidies will now bring the rescue at the last second.
Battery technology in its infancy

President Obama and his cabinet members these days cling to every straw. With the production of electric cars in the coming years, the U.S. economy will perhaps can make a big step out of the recession swamp, even if the automotive economic miracle, which is for the Americans, a symbol of their might heyday probably fail more . Nevertheless, everyone agrees that we must not miss this technology trend in any case and the industry received generous financial and tax benefits of aggregated approximately $ 480 million.
The Germans are now under pressure to act. Although his own plans seem ambitious to date and future-oriented, but the brash, aggressive action by the Americans could become a problem.
Here the people of Germany renewable energy, environmental protection and the impending change in technology is enormously important. Various Internet portals such as steckdose.de informed about innovations and opportunities of the green era.
Following the wishes of their constituents react now, the federal government by 2013 they will represent about one billion euros for research and development on electric vehicles available – until now the industry could expect about half of these funds. With this major investment in Germany is now trying to catch up. Economists see this as a good sign, however, warn against euphoria, since one could be the moment just be sure to have financial resources and technology plans – whether one will be fast enough to prove the chase still one of the leading positions , is another matter.
Auto expert Ferdinand Dudenhoeffer warns: “Daniel is jet to be a little bit. We must also produce. ”
Why Lithium-Ion batteries are so important?

This particular Dell Inspiron 9400 battery is characterized by a high energy density. It is thermally stable and not subject to memory effect (loss of capacity). For the electrical mobility, this technology is so important, because the lithium-ion batteries were devices with a relatively high energy requirement for the conventional nickel-cadmium or nickel-metal hydride Dell Inspiron 1545 battery too heavy or too large, may improve the supply of electricity. They established themselves as the best energy storage for electric vehicles.
By the performance and durability of these Dell Inspiron 640m battery in the future, sales of electric cars will be dependent. Why was stuck in the past few years a lot of money into researching and developing this technology.

What is memory effect of battery?

In general, liquid lithium and lithium-polymer battery is no "memory effect" for more. This can only NiCd and NiMH batteries have a very limited extent affected by the memory effect (inertia effect or battery). "Memory effect" refers to when a battery is continually only partially discharged before recharging them, makes the forgetting of the Dell Inspiron 6400 battery further unloading, down, such as: When you load normal as your battery completely and then only 50% of its capacity use before you charge it the next time the battery will eventually not be aware that it has an additional 50% of capacity which is remain unused. Your battery is still functional, but only 50% of their original capacity. To avoid the dreaded "memory effect", a fully cycle (fully charge and then fully discharge) your battery at least once every 2-3 weeks out. By pulling the AC adapter, batteries can be discharged until the battery is empty. Thus it is guaranteed to use your battery is highly effective and accurate.
What is the cycle batteries?

Each time a battery is charged and discharged, we call it a cycle. In the process of charging and discharging will change the battery capacity and the number of this cycle is called a life of a Dell Inspiron 9400 battery.

Normally, a rechargeable battery has a lifespan of 500-800 or more cycles. Even more simply, that they can use for one to one and a half years time.

With the increase in battery life, you may notice that the battery is running less and less time. For example: In the beginning, the battery can supply your phone 3 days, but now reduced to only about 1 day. If so, you have to replace the time certain new battery.
Good usage habits

First With the appropriate battery
When replacing the battery, you need to know the type and size of your Dell Inspiron 1720 battery and replace the same assessment battery type as possible.
Second Cleaning of the positive and negative contacts
Because of the influence of the conductivity by dust and dirt you need to occasionally clean the positive and negative metal contacts inside the battery compartment.
Third Timely removal and replacement
If these instructions "low battery" see, you have to recharge the battery in time. You should remove the completely discharged battery without recharge, this could lead to over-discharge the battery due to permanent damage. If you use your batteries in the long term, it should be removed from the machine and into a dry, cool and clean place to be stored. Even if the device is turned off, the system will still display a weak battery, which will shorten the life of the batteries.
4th Use and storage at low temperature
In bitter cold, you must avoid if possible, to cause the battery in the open, and pay attention to the temperature outside of the Dell Inspiron 700m battery. The storage of the battery at low temperature may slow their self discharge, but keep in mind to avoid before using the rope.
5th Avoid a short circuit
In any case, if the outer ends of the battery is connected to a conductor will cause the external short circuit. Short circuit of different battery types may yield different proportions result. Such as: the battery can not be used, leakage, explosion, etc. Put this battery to moisture and not mixenSie this with the head, such as If you have a key and simultaneously put the battery in your pocket, it can cause short circuits.
Laptop Charger AC Adapter for use:

First Dell Inspiron 6400 AC Adapter can last for a long time with proper use. The loss of the power supply is usually in the circuit. As the wall outlet and connect the power cord / cable and power supply, which are easy to bend, leading to the faulty or unwanted connection of the power cord. Caution should therefore be given to these special conditions.

Second Try not to use the Dell Inspiron 1525 AC Adapter under the open sky or in the poor environment, otherwise they will be exposed or damped.

Third Unplug the power cord when not using the laptop adapter, because his life is affected by long-time charging.

4th Although Dell Inspiron 1720 AC Adapter are all marked with broadband operating voltage 100V-240V, it will be more or less destroyed in the unstable voltage.

Dell Inspiron 1545 battery has not reflected light

Dell Inspiron 1545 laptop:

It recorded 58sec in our Blender 3D rendering test and 1min 16sec in our iTunes MP3 encoding test, and these results are pretty much what we expected. In our DVD transcoding test achieved the 1 hr 13min, which is also close to what we expected. All these results are competitive when compared other second-generation Intel Core i3 notebooks that we've seen before, like the Dell Inspiron 15R N5110 compared. It was a fraction slower speed in the blender and iTunes tests than the Dell, but their time transcoding 2min than the Dell. The Dell 6400 is hard drive was slow but the recording only 18.43 megabytes per second (MBps) to copy files in our tests. We expected it to come close to 30Mbps.

The Dell MD 96 370 is the company's first second-generation Intel Core i3-based laptops (codenamed Sandy Bridge), and as with most Dell products that we have seen over the years, it will offer good value for relationship. There is a 2.6 kg, 15.6-inch desktop replacement notebook with good speed, Dell Inspiron 1720 battery life and features, but the design could be better.

Specifications and Performance

Physically, the MD has a square shape with angled corners, its surface is shiny, and it has only one button on its chassis (for electricity). It feels fairly solid looking for a cheap laptop, although some creaking is noticeable at times when pressure is placed on the right palm rest. The touchpad is a little too small for a desktop replacement laptop size (40x82cm) and it has a texture that can sometimes feel, too resistive. We are also not fans of the cast for the left and right buttons lick - we wish it had separate buttons to press would be more comfortable.

You can use the MD as a media center. It comes with a USB digital TV tuner and a remote control. You must be in the included USB receiver plug, if you want to use the remote control, however, that two USB ports to be made means. A small antenna is supplied with the TV tuner, but it is probably only of limited use and will not work in many areas (Ten and One HD is found in the test), so that you are better off with a roof antenna. It brings the standard and high-definition stations.

Dell has a quick-boot feature to this disc, the Linux-based, in the form of a pre-Windows operating system environment called Dell introduced Fast boat manifest. This environment allows you to browse the Internet (Google Chrome), use instant messaging (Pidgin), Skype, browse files on the hard disk (Nautilus) and playback of media files (VLC). It also has Twitter and Facebook apps. It only takes a few seconds to boot in this environment (by pressing F9 key immediately after switching on the laptop), now it takes 1min 12sec in Windows 7 Home Premium to boot. With the installed OS Switcher software, you can also Dell Fast Boot is the preferred operating system when you turn on the notebook.
What we do not like about the design of MD is its overly bright blue status LEDs. You are on the palmrest itself and are very annoying when the laptop is used in a dark environment. We wish that he neither dimmer lights or that the existing LEDs were placed at the front of the case and not direct light upward.

With the MD on the lap can be uncomfortable due to its size, but the good thing is that their base is not too warm. Its speakers are fairly loud, but their quality is not great, so you should definitely plug in some speakers, if you want it to sound serious. We are fans of the screen that has a native resolution of 1366x768 and a matte surface that is not reflected light. Like most notebook screens but poor vertical viewing angles, which can cause havoc with the contrast, especially when watching videos.

Around the edges of the enclosure you will find many old and new stuff: There's a built-in DVD burner, an SD card slot, headphone and microphone ports, VGA, HDMI, Gigabit Ethernet, three dedicated USB 2.0 ports and one shared USB 3.0-2.0 and USB port. You also get a webcam, Bluetooth and 802.11n Wi-Fi (Intel Centrino Wireless-N 1030).

The keyboard has full-sized keys and includes a number pad, although the keys are smaller and the layout is a bit awkward (for example, the right arrow key is located on the 1 key and the 0 key will be completely under the 2 key). The keys feel a little stiff, but overall it is not hard keyboard to type and you get used to it after a while use.

What we do not like about the design of MD is its overly bright blue status LEDs. You are on the palmrest itself and are very annoying when the laptop is used in a dark environment. We wish that he neither dimmer lights or that the existing LEDs were placed at the front of the case and not direct light upward.
