Hybrid Batteries That Won't Explode

Battery manufacturer, Valence Technologies, has been promoting the fact that their new lithium ion Saphion battery, will not explode when used in hybrid cars. Lithium ion batteries are more energy-dense than nickel metal hydride cells currently used in most hybrid and electric cars. That means a lithium ion battery can run at a higher power for a longer time than a nickel metal battery of the same weight. But most lithium cells use a cobalt oxide chemistry that can catch fire or explode if the battery is charged or discharged too quickly, or if it is physically damaged. Valence is aiming to open up new markets for lithium ion technology by proving that lithium can be safe, a move that would challenge both nickel metal hydride and lithium ion cobalt oxide cells. :: Wired
