Rechargeable batteries have emerged as ubiquitous and indispensable technologies of the 21st century, propelling myriads of consumer electronics and ushering a new era of electric vehicles and stationary grid storage. Since the commercialization of Li‐ion batteries by SONY (approximately in the year 1991), the secondary battery sector has seen unprecedented growth with diverse applications touching global populations across socioeconomic strata. There is a steady quest to develop a wide range of batteries to cater diverse global demands from milliwatt‐scale electronics to megawatt‐scale grid‐storage applications. In this journey, Li‐ion batteries are complemented by various post‐Li‐ion chemistry (e.g., Na+, K+, Mg2+, Ca2+, and Al3+‐ion batteries), conversion mechanism‐based systems (e.g., Li–S, Na–S, and Li–O2) as well as renewed development of pre‐Li‐ion era technologies like aqueous batteries. Cathodes sit at the core with command over the net cost and performance of batteries. Various polyanionic cathodes have been developed to date, often guided by structure of naturally occurring minerals. One such mineral system is alluaudite, named after French geologist François Alluaud. The current article portrays the discovery and development of the alluaudite class of polyanionic cathode materials for rechargeable batteries. The structure and electrochemical properties of various alluaudite insertion materials are gauged along with possible future perspectives.

钙铝石电池阴极

可充电电池已成为21世纪无处不在的技术,推动了无数消费电子产品的出现,并开创了电动汽车和固定电网存储的新时代。自索尼将锂离子电池商业化(大约在1991年)以来,二次电池行业出现了空前的增长,其多样化的应用触及了社会经济各阶层的全球人口。人们一直在寻求开发各种各样的电池,以满足从毫瓦级电子产品到兆瓦级电网存储应用的各种全球需求。在此过程中,锂离子电池还辅以各种锂离子后化学成分(例如,Na +,K +,Mg 2 +,Ca 2+和Al3+离子电池),基于转换机制的系统(例如Li–S,Na–S和Li–O 2),以及锂离子时代之前的技术(如水性电池)的最新开发。阴极是控制电池净成​​本和性能的核心。迄今为止,已经开发了各种聚阴离子阴极,通常以天然矿物的结构为指导。一种这样的矿物系统就是以法国地质学家FrançoisAlluaud的名字命名的Alluaudite。当前文章描述了用于可充电电池的钙铝石类聚阴离子阴极材料的发现和开发。测量了各种钙铝榴石插入材料的结构和电化学性能以及可能的未来前景。
