Chinese lithium-ion battery manufacturer Sinopoly Battery Limited has signed a Letter of Intent with Smith Electric Vehicles to supply batteries for 20 000 electric vehicles destined for China.

The deal will be worth US$100m for Sinopoly to manufacture batteries for Smith’s commercial electric vehicles. Smith is making 15 000 for mainland China and 5 000 for Taiwan.

Breakthrough in lithium-air cell technology

Wed, 08/15/2012 - 18:02 -- Ruth Williams

Advances made in lithium-air battery technology by researchers at the University of St Andrews, Fife, Scotland, could provide ten times more energy density per mass unit than conventional lithium-ion batteries.

Battery chemist Peter Bruce believes the driving range of EV’s can be pushed beyond the 300 mile driving range with the lithium air technology which he believes has the potential to provide a transformational shift in transport.

If successful, lithium-air batteries could decrease the weight of the battery pack because they use oxygen to charge the electrodes. The design would be of a similar design to zinc-air batteries used in hearing aids.

A previous stumbling block to using lithium-air cells has been the unstable chemical reaction causing the battery to fail after a couple of cycles.  This may be overcome with the work done at St Andrews where they were able to run a lithium-air lab cell for 100 charge-discharge cycles.

Clearly there is a long way to go before this could be a commercially practical option, but this step is part of a giant leap in the future of battery technology.

Emergency home power from EVs

Mon, 07/23/2012 - 18:02 -- Ruth Williams

Progress is being made to develop EV batteries to be utilised to power homes during times of blackout. Following the 2011 Japanese earthquake much of the country was without electricity, EV batteries were used as a temporary in-home power supply.  Hybrid cars that feature an invertor can have the high-voltage direct current switched to a low-voltage alternating current to supply power back to a home at times of blackout. Nissan are leading the way in advancing this potential, they believe their Leaf car could power a home for up to two days, or individual appliances for far longer.
