Hybrid Battery/Supercapacitor Energy Storage Device

ADA, in collaboration with USC, proposes the development of a high energy hybrid battery/supercapacitor to replace multiple heterogeneous energy storage devices currently used by the Army soldier. The hybrid electrical energy storage system (HEESS) will be developed incorporating ADAs high energy supercapacitor and a commercial-off-the-shelf high energy Li-ion battery through an externally paralleled hybrid system developed by USC to develop a hybrid battery/supercapacitor with the pulse capabilities of a supercapacitor and the specific energy of a Li-ion battery. A HEESS that couples the attributes of a Li-ion battery (high energy, low cost, etc.) with those of a supercapacitor (high power, specifically pulse power, long life, wide operational temperature range, and safety--especially during high charge currents) would afford an unprecedented energy storage device.
