Advanced Lithium Ion Batteries for Space-based Applications

The objective of this proposal is to demonstrate the feasibility of developing advanced battery chemistries that provide batteries that operate safely at increased power density via improved discharge rate, higher energy density through improved battery internal components/chemistry/cathode and anode material, increased cycle life and depth-of-discharge, exceptional durability when exposed to extremes in temperature and space environmental effects and an increase or total elimination of the calendar-life limitations of lithium ion batteries. During the phase I of this program, Yardney will manufacture surface modified cathode materials and apply novel coating technology. The cells made from theses electrodes will be safe, long life and better electrochemical characteristics for space based batteries. BENEFIT: Air Force Application: The target application for this surface modified cathode based Li ion battery is in Air Force applications where safety, longer cycle life, high energy density and power densities are required. This new technology will have superior performance even at low temperatures due to robust electrode coating method and surface modification of the electrode materials. Non Military Application: High power applications include power tools, electric vehicles and telecommunications. Automotive and industrial sectors, where the slim, small-sized battery will deliver large amounts of energy while requiring only a minute to recharge. For example, the battery''''''''s advantages in size, weight and safety highly suit it for a role as an alternative power source for hybrid electric vehicles.
