High Specific Energy and Power Solid-State Energy Storage Device

To meet the current and future needs of the Army, improved power systems are needed for missiles, sensors, communication systems, night-vision devices, and other applications. Although conventional batteries can provide power for a wide variety of duty cycles, current batteries do not provide sufficient power to meet high power demands of multiple applications. Ultracapacitors can meet the high power demands, but do not provide sufficient specific energies. Lynntech proposes to develop an advanced energy storge device that provides high specific energy and high specific power and is both solid-state and flexible. The energy storge device is based on combining advanced electrode and electrolyte materials that provide rapid discharging and high capacities. During Phase I, the electrodes and electrolyte will be developed and tested to meet specific energy, specific power requirements. During Phase II, Lynntech will optimize the cell components and fabricate and test scaled-up cells to target military specifications. The energy storage device will provide a solid-state flexible power source for multiple battlefield applications including miniaturized sensors, communication devices, and missiles.
