This DOD Air Force SBIR program focuses on developing and commercializing a nanomaterials-based high rate rechargeable battery technology that provides performance, weight and safety advantages for aerospace applications. The proposed research builds on T/J Technologies’ innovative electrode materials and extensive system-level development of high rate Li-ion rechargeable batteries. In Phase I, we successfully demonstrated a 60C (1 minute charge/discharge) anode capacity of >50 mAh/g and a 60C cathode capacity of >50 mAh/g. We also obtained 2,000 stable cycles in a laboratory prototype Li-ion cell with 100% DOD (depth of discharge) at 20C charge/discharge (3 minute charge/discharge). The goal of this Phase II proposal is to build prototype Li-ion batteries at TRL 5 and demonstrate the feasibility of replacement of AgZn batteries presently used in Delta IV launch vehicles. In Phase II, we will scale-up electrode materials synthesis and optimize cell architecture for launch vehicles or other selected aerospace applications. In addition, we have partnered with a commercial battery manufacturer to make prototype large format, high rate Li-ion rechargeable cells for independent performance evaluation. For some specific applications, the emphasis will shift to higher energy density systems.
