BETTERGY CORP. — Department of Defense SBIR Phase I: A14-073

Description

Military operating have increasing demand for battery power source in a wide variety of applications for communications, high-power weapons and vehicle applications. There is a huge imbalance between battery development and power requirement by the military. Lead acid battery because of its low cost, safety and high level of recycleability is still holding the dominant share in the military as well as the commercial rechargeable battery market. However, its low specific energy (< 35 Wh/kg) and short deep cycle life (< 150) severely limit its adoption in the new generation military vehicle applications. In this SBIR program, an innovative bipolar lead acid battery withlight weight, corrosion resistant current collector and unique design concept will be developed to address this urgent demand. It is expected that this novel bipolar lead acid battery will have 1) > 60 Wh/kg; 2) >150 Wh/L; 3) > 300 deep discharge cycles; 4) higher power density than the conventional VRLA while maintain the same level of battery cost.In the Phase I program, we will confirm and demonstrate the feasibility of our approaches, carry out the system analysis and conceptual design and deliver the cells for independent evaluation.
