The battery is the heart of an electric car - and also the number one object of research. Now there are signs of a breakthrough with lithium and air. But it will take until then a little bit.
Hauke Schrieber from the electric car is ready. Models such as Mitsubishi i-MiEV (photo) or Nissan Leaf show that construction and operation represent no more problems. Crucial weak point but are still the batteries: they are too expensive and too hard to allow enough range to have long load times and large temperature sensitivities. Modern lithium-ion batteries, as used for example in leaf weigh 250 kg and more, their energy density of about 170 watt hours per kilogram allows a maximum range of 160 kilometers. That's enough for many drivers though - but only for the second car.
The Karabag Fiat 500E runs with a lithium-polymer battery - including in large-AUTO BILD endurance test. To make the battery-electric car is really suitable for mass production, more powerful batteries need to be developed. After interim solutions such as lithium-polymer (used already in Karabag new 500E), the next generation of batteries produced in lithium-sulfur base. It could allow a range of up to 300 kilometers (see table below). The final breakthrough in battery technology, scientists expect in a good ten years from the lithium-air battery. Here, the cathode is replaced by oxygen from ambient air. The anode is metallic lithium. This makes the battery lighter and more compact.

Rock Tech Lithium: 3D video of the drill and the highlight of the company `s from 2011
Mining - Rock Tech Lithium Inc. is a Canadian company focused on developing its lithium and rare earth projects in Canada. The company owns 100% each of the Georgia Lake project in the Thunder Bay Mining District of NW Ontario, Kapiwak of the project and the Lacorne project in the James Bay region in northern Quebec.
We, the team from the mining scout track, the company now since June 2011. We want to take up again at the end of a brief update of the highlights together, and we thank the management, particularly in Eunho Lee (Chairman & Managing Director) for their cooperation.
Management would not be so single-mindedly pursue the project, so we could inform you readers do not always progress through the company. And I think the Rock Tech Lithium excellently informed its investors that it has not always the case.
Let's talk about the highlights:

Lithium-ion batteries: BMW and Toyota in joint research
BMW electric car lithium-ion battery Toyota
Cleantech News / Munich, Japan. The BMW Group and Toyota Motor Corporation will strategically move closer together. BMW and Toyota announced today that they will jointly operate basic research in the field of lithium-ion battery technology for electric cars. It should go to the lithium-ion batteries, the "next generation". In addition, the BMW Group delivers fuel-saving diesel engines to Toyota Motor Europe. Generally, the companies plan to examine other potential projects in environmentally friendly technologies.
BMW and Toyota want to build better vehicles
"With this step we are joining forces to promote the development of environmental technologies and our innovation leadership in the respective segment," said Norbert Reithofer, Chairman of BMW AG. Akio Toyoda, president of Toyota Motor Corporation, said: "To promote the development of the automotive industry and society, both companies on their extensive knowledge and experience - first with environmentally friendly technologies - bring to the alliance, in order to build more and better vehicles."
The closer cooperation between Toyota and BMW is one of many "elephants marriages" that have emerged just in the field of electric mobility in recent years.
Unusual is that other people want to move about as in the cooperation between Volvo and Siemens, in this case, two OEMs in the automotive industry together. Strategically, the liaison but especially BMW makes sense is to suggest that BMW might also be interested in know-how of the Japanese in the field of hybrid technology. There the Europeans the Japanese car maker Toyota is still lagging behind.
