Abstract: |
With the continued electrification of military systems, lithium-ion (Li-ion) batteries are increasingly targeted for electrical energy storage due to their wide operating temperature range and exceptional energy density. However, Li-ion batteries operating in hostile thermal and mechanical environments typical of military aircraft are prone to catastrophic thermally-induced failures. Hazards including loss of power, fire, and explosion are unacceptable for airborne platforms. Consequently, there is great interest in advanced thermal management and thermal fault mitigation strategies to optimize pack performance and enhance safety. During this program, we will determine the feasibility of a novel multi-tiered approach coupling high conductance heat removal techniques with active monitoring and control strategies to improve the safety of Li-ion battery packs. During Phase I we will leverage previously developed Li-ion battery analytical models to demonstrate improved thermal performance with a subscale prototype. During Phase II we will complete development and conduct testing with a full-scale prototype battery pack. |
Benefits: |
The primary benefit of this program is the development of high-efficiency heat removal and thermal fault mitigation strategies that improve safety for a broad range of Li-ion battery chemistries, capacities, and configurations. This technology will enable the safe use of large format Li-ion battery packs for a range of aircraft; Hybrid and Electric Vehicle; and unmanned land, air, and sea vehicles. |
