飞机及其运行所在的航空生态系统是由技术要求、经济和环境问题之间的复杂交易塑造的，所有这些都建立在安全的基础之上。这一观点探讨了电池供电飞机的要求和有望实现这些要求的化学物质。强调了飞行和地面需求和化学之间的差异。安全、可用的比能而不是成本是航空业的主要制约因素。我们的结论是，如果有足够的航空应用投资，在未来十年内可能会实现比能量接近600千瓦时/千克的适合飞行的电池组。
Aircraft, and the aviation ecosystem in which they operate, are shaped by complex trades among technical requirements, economics and environmental concerns, all built on a foundation of safety. This Perspective explores the requirements of battery-powered aircraft and the chemistries that hold promise to enable them. The difference between flight and terrestrial needs and chemistries are highlighted. Safe, usable specific energy rather than cost is the major constraint for aviation. We conclude that battery packs suitable for flight with specific energy approaching 600 kilowatt hours per kilogram may be achievable in the next decade given sufficient investment targeted at aeronautical applications.
