Description

ABSTRACT: Remotely Piloted Vehicles (e.g. Raven and Dakota), are heavily relied on by U.S. Air Force warfighters for safe and successful completion of critical missions involving surveillance, intelligence, target acquisition, payload delivery and reconnaissance. Because onboard space on RPVs is limited, miniaturized power supplies, which can deliver high energy densities in scalable quantities, are needed to power instrumentation and flight termination systems. RPVs face extreme temperatures and power supplies must be capable of safe and reliable operation at high and low temperature regimes. Lynntech proposes to develop a miniaturized, smart, rechargeable, non-flammable Lithium-ion battery that will safely and reliably operate in the temperature range of -40 to +85 degrees C and will be capable of generating 30 Wh of energy, with scalable charge capacities (1 10 Ah). In order to accomplish this, Lynntech will develop a highly conductive, wide temperature range electrolyte/solvent mixture, during the Phase I project. A prototype based on the advanced electrolyte and high capacity electrodes will be fabricated and the performance demonstrated under varying loads of 0.25C to 2C. Phase II will focus on refining the prototype to meet military requirements (i.e. 30 Wh,<4 in3, military-grade parts, and smart software) and field testing. BENEFIT: Miniaturized, rechargeable Lithium-ion batteries that deliver high energy densities in high and low temperature regimes would satisfy the U.S. Air Force"s need for small power supplies for Remotely Piloted Vehicles, particularly the Raven and Dakota. The benefits of developed Li-ion batteries to the Air Force and other DoD agencies, include improved stability and reliability at extreme temperatures, increased safety, and high performance during critical operations. The developed electrolytes for wide temperature ranges will also benefit the private sector. Li-ion batteries based on advanced electrolytes designed for commercial products (e.g. consumer electronic devices and hybrid/electric vehicles) can have improved power densities, reliable operation in various climates and reduced risks of explosions. The most applicable market in the private sector for the developed technology would be the communications and transportation service.
