Big Blue has launched an ambitious battery project  with the a goal of commercializing an experimental battery technology — lithium metal-air — in order to acheive over ten times the energy density of today’s best batteries. This week, IBM will host a gathering of some of the world’s top researchers in the field, including auto company researchers and others involved with batteries for electric cars, to talk about moving beyond lithium-ion technology. Lithium-ion is the battery technology of choice for mass market electric cars under development at Nissan, General Motors and Tesla Motors.
