A123 Systems … said it has developed an improved lithium-ion cell that can cut costs of rechargeable and hybrid vehicles.
The “nanophosphate EXT” cells will be produced next year and can be used longer and operate more efficiently in extremely high and low temperatures than competing lithium-ion packs, the company said today. That reduces the need for systems in electric cars to maintain a consistent battery temperature, said David Vieau, A123’s chief executive officer.
“That will eliminate weight, cost, technical complexity,” Vieau said in a phone interview before today’s announcement. “That doesn’t solve all the cost issues but it’s a step in the right direction
