Abstract
Recent advances in electrode materials, manufacturing processes, and safety features are enabling Li-ion battery (LIB) designs to better support energy storage needs for the emerging all-electric aviation market. Increases in cell specific energy, improved fast charge and discharge rate capability, and extended cycle-life are required for the next-generation aviation platforms that consist of more-electric, hybrid, and all-electric aircraft designed to reduce generated flight noise and carbon emissions. The success of these emerging Advanced Air Mobility (AAM) markets is highly dependent upon implementing a safe and reliable energy storage system compliant with aircraft system requirements. This work discusses state-of-the-art (SOA) and emerging LIB technology readiness to meet the derived marketplace performance and imposed regulatory requirements for all-electric aircraft. A special focus on advanced LIB safety design guidelines intended to meet the intent of the FAA DO-311A minimum operational performance standard for rechargeable lithium batteries and battery systems installed on aircraft is emphasized.
