Research Institution
The Navy has established the need to replace the present high power sonobouy power source used in Air Anti Submarine Warfare (ASW) Systems. Present technology for the ASW sonobouy battery utilizes a primary Lithium/SO2 battery chemistry which provides for up to 20, 10 second pulses drawing 5500 W of power at 65 V. The present system poses a safety concern arising from the venting of toxic fumes due to the excessive heat generated upon discharge. During Phase I, MaxPower had successfully demonstrated the feasibility of using a Vanadium Pentoxide (V2O5)/Lithium primary battery as a safe alternative for high power applications. The Phase II effort will focus on incorporating this technology into a standard size wrap cell as well as improving the long term high temperature storage stability of this chemistry through the use of various electrolyte additives.
