Power package with great perseverance (B)

Marcel Groos, project manager for reputation would have liked - as well as Siemens - deep into the interior of the inspiron 1525 battery and looked done thorough testing. But he also understands that this is the Berlin-based start-up is too risky. Nevertheless, he remains on the ball: "We are in talks and want to install the battery in one of our cars."

If the Porsche are actually much further, would be stimulated, "sticking point for the electrical mobility is still the range," said Groos. Now it would not be equal to 1000 kilometers, but 300 would be good. In any case, reputation would even test whether the promises of Hannemann are realistic. Groos, "DBM is not out of the race, even if we know the inspiron 6000 battery technology is very costly."

Hannemann is the technique meantime to check the Federal Institute for Materials Research through its paces. "With the large-scale industry, we will not enter into partnerships," he says defiantly. There is currently with the little electric sports car manufacturer Lightning, several small aircraft engineers and logisticians in the conversation.

At a discount food store, the freight forwarder Eberl and packaging company Papstar be having their usual lead acid compaq presario v2000 battery forklifts compete against vehicles with hummingbird technique.

In 2009 a similar Papstar ran races with two identical forklifts: The Hummingbird for inspiron 6400 battery lasted about three hours longer, Papstar logistics chief Gregory Falcon could not believe it: "It blew us. We can imagine ourselves well, convert the entire fleet, "said Falcon. Hannemann was in January, the "Innovation Award of reason." Ironically Ex-Mercedes boss Juergen Hubbert to beat him and praised in the eulogy: "A car in the compact class with electric drive and a range of 500 kilometers is on the horizon."

The trophy is now in the barren and somewhat makeshift headquarters in Berlin between DBM inspiron 710m battery on the windowsill. The charm of the slightly chaotic founding, however, could soon disappear: The company wants to grow. Resulting in Thuringia and Baden-Wuerttemberg soon two new production plants. Mirko Hannemann is only beginning.

Researchers are looking for the super battery(B

A key problem is to concentrate as much as electrical energy in the smallest space. Researchers at the Fraunhofer Institute for Chemical Technology (ICT) in Pfinztal near Karlsruhe, therefore, attempt to replace conventional graphite electrodes from a1185 battery with materials from tiny, only a few hundred nanometers thick carbon tubes and fibers. This would dramatically increase the inner electrode surface. Normally, lithium ions move only between the graphite layers of the host lattice. A task that is called intercalation. The Nanokohlenstoff from Pfinztal is also different here: "If nanotubes are deposited lithium-ion addition to the edges and surfaces of material layers. Nanotubes can also be manufactured so that a much larger proportion of occupied Interkalationsschichten of lithium-ion inspiron e1505 battery ," says Jens Tübke head of ICT at the Department of Applied Electrochemistry.

Meanwhile, the researchers were able to increase the discharge capacity of nano-batteries to about 800 milliampere hours per gram (mAh/g). Classical graphite vgp-bps5 battery provide only 300 mAh / g. Nor is the production of micro-carbon nanotubes-consuming and expensive.

Ten times more lithium ions per gram of silicon can store as an electrode material in comparison to graphite. To the chagrin of the researchers, however, increased fourfold while the original volume of the brittle semiconductor materials. The result: After a few charge cycles to show cracks. Here, too nanostructures to solve the problem. For example, researchers at Stanford University are experimenting with micro-fine silicon tube as an electrode material of latitude d510 battery . In the nanofibers mechanical stresses during loading and unloading can survive obviously much better than normal silicon crystals. In addition, the mini-tubes can be produced with the chip production process from relatively inexpensive.

In the laboratories of Stefan Koller, Institute of Chemical Technology of Materials at the Technical University of Graz are also lithium-ion inspiron 1520 battery tested with silicon electrodes. The Austrian researchers battery is however a containing silicon gel which is deposited on graphite as a substrate material. "It has graphite as a buffer to absorb the large volume changes of silicon in the ion absorption and emission," said Koller. The new material could thus save an unchanged lifetime, more than double the amount of lithium ions. Challenge, however, remains the poor density of the materials in the electrode.

High-performance inspiron 1721 battery should base on lithium-ion plating,and are used for electric vehicles such as energy, the relatively long time to load the batteries can quickly be the Achilles heel of the technique. Until now, battery experts have always assumed that lithium ions during charging is not fast enough to move through the respective electrode material. A computer simulation, carried out the Gerbrand Ceder, Massachusetts Institute of Technology (MIT) in Cambridge (USA), but then placed near the opposite: the example of the standard material lithium iron phosphate (LiFePO (-4)) showed cedar that lithium-ion moving within the electrode downright brisk. But they are thwarted by the limited number of access channels in the crystal lattice, which are also difficult to reach. The result is a jam of the charge carriers.

Wireless power Juice of the session (A)

Using electromagnetic induction, we will continue to recharge your pavilion zv6000 battery . With some minor equipment that is already possible. Induction in a big way, however, could burden the people.

With the electric toothbrush works for example, already: If your Compaq Battery is empty, place the device easy to Grips, and even the energy to be recharged. It is as if by magic, as an electrical contact between the charger and toothbrush does not exist. The wireless transmission of energy works on induction. According to the ideas of some scientists, this principle could in future also in many other electronic appliances as standard. Even the electric cars of the future could boost their energy again, without a man needs to lend a hand and make a cable connection.

The principle of induction was the Briton Michael Faraday discovered in 1831: To a leader who is traversed by electric current forms a magnetic field, recognized the physicist. This magnetic field generated in a second, closely adjacent conductor also has a current flow and can therefore be used to transfer energy. From this discovery, finally emerged the idea of using magnetic fields for energy transfer. Precisely what also manufacturers of electrical appliances such as Acer Battery , HP Battery ,and Lenovo Battery in mind. They have joined forces in Wireless Power Consortium (WPC) and to create a common goal set in the course of the year 2010, a uniform standard for wireless recharging of appliances. The reported technology journalist Michael Bird in an article in the April issue of the magazine "Bild der Wissenschaft".

A Ladematte for all devices

A single charger that can recharge the thinkpad t61 battery of mobile phones, digital cameras and MP3 players. It would consist of a mat with incorporated coils generating a magnetic field. The corresponding small appliances need to recharge itself, of course, be equipped with the appropriate technology. Such mats are sold even though isolated, but the device before loading must be provided so far still with a special adapter spool. How quickly the uniform of WPC targeted technical standard for the induction technology will prevail in the market, there will be Menno Treffers, Chairman of the WPC did not specify. "The integration of the coils in the devices such as cell phones or cameras, but is not a problem," says strike will be responsible for the standards at Philips, told Bild der Wissenschaft ".

With the distances between the coils of no more than a few millimeters, the transfer is to achieve the a1185 battery efficiency of around 70 percent. For longer distances, however, the efficiency goes down dramatically. Even more power especially when traveling over greater distances hopes that the physicist Marin Soljacic of the Massachusetts Institute of Technology (MIT) with his idea, which he now wants to also develop a technical solution. The two coils here are coordinated so that the magnetic field can only transmit at a given frequency energy. Through a clever construction it can reach so that the corresponding receiver coil but receives a lot of energy, other objects in space, however, very little. Thus Soljacic could bring in the lab already has a distance of two meters, a 60-watt light bulb to illuminate.
