High Power, Long Endurance Battery

MaxPower incorporated is dedicated to the continued development of a high power battery utilizing a novel cell design coupled with a rate capable cathode formulation based upon a primary Lithium/Vanadium Pentoxide chemistry. Originally developed as a safe alternative to the 42 cell, Li/SO2 battery under SBIR Topic N092-110, Maxpower has matured this technology from laboratory scale cells through to the demonstration of a 5000 Watt battery under an active Phase II.5 program. This work has provided sound engineering data, design confidence, and the experience necessary for the next step in the evolution of the high power Vanadium Pentoxide system. Preliminary work at the cell level has demonstrated the baseline 5/4 C size cell is capable of delivering 155 Watts for 110 seconds, while preliminary lab scale optimization of the cathode slurry formulation has already yielded increased capacity which, when integrated into the full scale system, will produce a battery capable of 160 seconds of life at 6500 watts. Additional work under this Phase I program will further optimize the cathode and bring the system closer to the 200 ping-second target while allowing the power capability for even higher power capability in the future utilizing alternate cylindrical or prismatic cell formats
