Lithium-ion batteries are great and all—having heralded in a new age of portable electronics and allowed for the possibility of mass-market electric cars—but they have a few major drawbacks. For instance, they have a propensity to catch fire and explode and, although they have a much better energy storage capacity than say lead-acid or nickel metal hydride (NiMH) batteries, they still weigh too much to pack more than a couple hundred miles of range into a passenger car.

VW premiered its spanking new EV concept, the E-Up!, at the Frankfurt Auto Show yesterday, and gave the strongest hint yet that the car will be very close to the production model available from 2013.

The E-Up! boasts acceleration to 62 mph in a fairly zippy 11.3 seconds and tops out at 84 mph, whilst its 18 kWh integrated lithium-ion batteries will enable a range of over 80 miles (see picture gallery after the jump).

Toyota has revealed that its eagerly anticipated iQ-based all-electric car will receive its own individual body-style makeover, to create a stand-alone model set to become Toyota’s first all-electric car.

It appears that the electric iQ, due for launch in 2010, will not be pushed in the same market sectors as the original. Speaking about the strategy Hiroki Nakajima, chief engineer for the iQ said, “We wanted to position the iQ as premium, but not so the BEV (battery electric vehicle).” Perhaps they think that your average EV user is a little more low-rent than other drivers?

Researchers at the Massachusetts Institute of Technology (MIT) have developed battery cells capable of charging in under a minute, an astonishing 100 times faster than a regular rechargable battery.

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years.

The discovery came when MIT researchers Byoungwoo Kang and Gerbrand Ceder found out how to get a common lithium compound to release and take up lithium ions in a matter of seconds. According to Ceder, the compound, known as lithium iron phosphate (LiFePO4), has a crystal structure that creates “perfectly sized tunnels for lithium to move through,” allowing the team to reach “ridiculously fast charging rates.”

A Japanese professor has showcased an electric car capable of reaching a blistering 100 km/h (62 mph) in 4 seconds, quicker than a Porsche 911 [video].

The Eliica, created by Prof. Hiroshi Shimizo of Keio University, can also reach a phenomenal top speed of 370 km/h (270 mph), powered by li-ion batteries via 100 hp electric motors in each of its eight wheels.

Shimizo is understandably proud of his creation, telling reporters, “The feeling of acceleration you get with this model is something automotive technology could not produce, even in a hundred years of combustion engine cars.”

Battery provider Southern California Edison (SCE) has demonstrated a lithium ion battery with a lifespan of more than 180,000 miles, a major milestone in advanced battery performance that opens the door to a new generation of electric cars.

Since the average U.S. family car travels less than 15,000 miles each year, the battery could easily provide more than ten years service before it needs replacing. When you factor in the relatively low servicing costs of electric cars, this means that there is now a compelling case for such technology to power future plug-in vehicles.
