Mining firms link up for next-gen batteries R&D

Two mining firms have formed a joint venture to develop both lithium-air and lithium-sulfur batteries in a bid to drive the market for palladium and platinum.

Canada-based Platinum Group Metals (PGM) and South African firm Anglo American Platinum (APP) launched Lion Battery Technologies to accelerate the use of platinum and palladium in lithium-air and lithium-sulfur battery technology.

Discovery could pave way for lithium-air batteries

Lithium-air batteries are a step closer to market readiness after researchers made a breakthrough at a German university.

Rechargeable lithium-air batteries could be the next big thing, offering better performance at a lighter weight, theoretically at least.

UK grant signals sea-change in attitude toward next-generation lithium battery technology

It may be a few years behind the rest of the world but the UK is at least trying to make up for lost time with a series of funding rounds aimed at developing the nation’s battery credentials.

The latest series of funding enables a team of chemistry, engineering and materials groups to develop next-generation lithium-ion and lithium-air batteries for electric vehicles and energy storage systems.

IBM and JCESR step back from lithium-air research

US labs IBM and Joint Center for Energy Storage Research (JCESR) have downgraded their research on lithium-air technology.

Lithium-air is widely seen as the 'holy grail', not least for for EV batteries. Using the oxidation of lithium at the andoe and the reduction of oxygen at the cathode to induce a current, lithium-air - if ever made to work cost-effectively over sufficient cycles - could lead to batteries with a range of 500 miles drives on a single charge - up to five times more than the average pure EV.

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.
