High Energy Density, Fast Charge Lithium-ion Batteries

The need for a high specific energy, fast charge battery for the U. S. army is recognized. The proposed Phase I program addresses to investigate the feasibility of developing prototypes 7.5 Ah lithium-ion cells having specific energy >210 Wh/kg which will be used as `building blocks' for the development of BB-2590 ibatteries in Phase II.A novel electrochemical couple is proposed for the development of a fast charge,high specific energy lithium-ion battery system. The proposed anode material delivers 50% higher practical capacity than the state-of-the-art carbon anode materials. Several prototype lithium-ion cells will be developed and their performance will be evaluated to demonstrate the proof-of-concept.
