Li-ion batteries have revolutionized the portable electronics industry and empowered the electric vehicle (EV) revolution. Unfortunately, traditional Li-ion chemistry is approaching its physicochemical limit. The demand for higher density (longer range), high power (fast charging), and safer EVs has recently created a resurgence of interest in solid state batteries (SSB). Historically, research has focused on improving the ionic conductivity of solid electrolytes, yet ceramic solids now deliver sufficient ionic conductivity. The barriers lie within the interfaces between the electrolyte and the two electrodes, in the mechanical properties throughout the device, and in processing scalability. In 2017 the Faraday Institution, the UK’s independent institute for electrochemical energy storage research, launched the SOLBAT (solid-state lithium metal anode battery) project, aimed at understanding the fundamental science underpinning the problems of SSBs, and recognising that the pauci...

2020年固态电池路线图

锂离子电池彻底改变了便携式电子行业，并推动了电动汽车（EV）的革命。不幸的是，传统的锂离子化学正接近其物理化学极限。对更高密度（更长距离），大功率（快速充电）和更安全的电动汽车的需求最近引起了人们对固态电池（SSB）的兴趣的兴起。从历史上看，研究集中在改善固体电解质的离子电导率上，但是陶瓷固体现在可以提供足够的离子电导率。阻挡层位于电解质和两个电极之间的界面内，整个装置的机械性能以及工艺可扩展性内。2017年，英国独立的电化学储能研究机构法拉第研究所（Faraday Institution）
