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.

下一代航空锂离子电池技术——实现电气化飞机

电极材料、制造工艺和安全特性方面的最新进展使锂离子电池(LIB)设计能够更好地支持新兴全电动航空市场的储能需求。下一代航空平台需要提高电池比能量，提高快速充放电能力，延长循环寿命，这些平台包括更多的电动、混合动力和全电动飞机，旨在减少产生的飞行噪音和碳排放。这些新兴的先进空中机动(AAM)市场的成功高度依赖于实施符合飞机系统要求的安全可靠的储能系统。这项工作讨论了最先进的(SOA)和新兴的LIB技术准备，以满足衍生的市场性能和对全电动飞机的强制监管要求。特别强调了先进LIB安全设计指南，旨在满足FAA DO-311A可充电锂电池和飞机上安装的电池系统的最低操作性能标准。
