Hybrid Battery / Capacitor Power for Increased Power and Energy Density and Safety

Improvements in rechargeable battery energy, power, cycle life and safety are required for the F-35 Joint Strike Fighter Program. During Phase II, Giner, Inc. will use its advanced lithium-ion hybrid cell chemistry developed in Phase I, together with improvements in packaging designs to achieve the necessary energy and power densities to meet Naval Aviation requirements. A batch-level coating method will be implemented to produce electrodes for the prototype energy storage device. The trade-offs between specific power and specific energy will be examined experimentally to optimize electrode composition and design. Scalable performance will be demonstrated in prototype cells over the temperature range of -40oC to +71oC Cell stability will be evaluated with exposures of +85oC storage temperature and at low ambient pressure. Cell case designs and self-diagnostic/prognostic capabilities will be addressed to ensure safety, performance and service life when packaged into the 28 Volt DC electrical energy storage device.
