BHAWIN LLC — Department of Defense SBIR Phase II: SOCOM222-001

Description

In Phase II project, Bhawin LLC aims to fabricate the current concept of solid-state Li-ion battery fabricating a single continuous phase for the anode, electrolyte, and cathode, and thus, eliminating the highly resistive interfaces between the electrolyte and electrodes found in straight solid-state Li-ion batteries. Advanced Li-ion battery technology will play a critical role in the understanding of Hybrid Electric Vehicles, Electric Vehicles, and the increasingly critical field of renewable energy. Current solid-state Li-ion batteries have much lower energy and power densities than liquid electrolyte batteries due to the use of three different materials for the anode, the cathode, and the electrolyte causing high interfacial resistance between the solid electrolyte and the solid electrodes. This project focuses on optimization of synthesis process (1) quasi-solid-state electrolytes (2) NMC811, LiFePO4 and (3) Li4Ti5O12/Graphene anode (4) Li6.4La3Ta0.6Zr1.4O12 and Li6.4La3Ga0.2Zr1.8O12 solid state electrolytes and electrochemical performance solid-state Li-ion batteries to achieve high energy density of >350Wh/kg with 50Ah electric charge. On a follow-on Phase-III project this technology will be commercialized by a leading lithium-ion battery manufacturer who is very much interested in this technology.
