Chron: 972178

Proposal Number: 19.02-9450

Project Title: Long Cycle Life, High Energy Density Li-Ion Battery

Technical Abstract (Limit 200 words)

The battery is based on a novel lithium intercalation anode which we expect to a) double the capacity of graphite anodes, b) eliminate the irreversible capacity from electrolyte reduction, c) enhance safety over conventional anodes and d) greatly extend cycle life. Coupled with our advanced polymer electrolyte and high voltage cathode, we expect a fully developed battery to have a pecific energy of >150 Wh/kg, an energy density of >300 Wh/l and the capability to provide >1000 deep charge/discharge cycles. This Li-ion battery would also be safer than its carbon anode counterpart, especially in the larger sizes of 20-50 Ah needed for many space applications.The proposed Phase I effort is designed to demonstrate the feasibility of our approach by synthesizing and physically and electrochemically characterizing the new Li intercalation anode host material. More extensive anode and cell development will follow in Phase II.

Potential Commercial Applications (Limit 200 words)

The new Li-ion battery will find wide application wherever high energy density, safety and long cycle life are important. This includes portable computers, communication equipment, camcorders, power tools and autonomous robots in remote locations.
