Exxon-Mobil Corporation, US's largest refiner and one of the world's largest oil companies has been carrying out research in technologies that can improve Lithium-ion batteries - the mainstay of many hybrid car propulsion systems.

Anyhow, once the heating issue is resolved, the market for Li-ion should pick up and that is where Exxon's focus happens to be.
