Started in 2009, the project is run by IBM Research from its facility in Almaden, California and is focused on building a new generation of lithium-air battery packs. These are ten times more energy-dense than conventional lithium-ion units, which would allow carmakers to fit smaller battery packs with a longer range than is available now.

Japanese chemical manufacturer Asahi Kasei brings its knowledge of separator membranes to the project, while Central Glass will add its expertise in electrolytes to build a new type of high-performance additive to the unit.

Dr. Winfried Wilcke, IBM’s principle investigator, said: ‘These new partners share our vision of electric cars being critical components of building a cleaner, better world, which is far less dependent on oil. Their compatible experience, knowledge and commitment to bold innovation in electric vehicle battery technology can help us transfer this research from the lab onto the road.’
