Due to the rapid battery market expansion, and the limited and geographically concentrated lithium and cobalt resources, there is significant concern regarding the short-term supply and long-term sustainability of lithium-ion batteries (LIBs). Potassium-ion batteries (KIBs) are emerging as a promising complementary technology to LIBs due to the relative abundance of potassium. KIBs can also use graphite anodes providing a critical advantage over sodium-ion batteries (NIBs). In this perspective, we provide an overview of the most promising cathodes, anodes, and electrolytes to date for KIBs. We also present a concise techno-economic model to critically compare the most promising KIB chemistries and evaluate if they can compete with a leading NIB and LIBs. Finally, we identify five critical research challenges that need to be addressed for KIBs to become a viable technology.

钾离子电池展望

由于电池市场的快速增长,以及锂和钴资源的有限和地理集中,锂离子电池(LIB)的短期供应和长期可持续性引起了人们的极大关注。由于钾的相对丰度,钾离子电池(KIB)成为锂电池的有前途的补充技术。KIB还可以使用石墨阳极,这比钠离子电池(NIB)更具优势。从这个角度出发,我们概述了迄今为止KIB最有希望的阴极,阳极和电解质。我们还提供了一个简洁的技术经济模型,以严格比较最有前途的KIB化学,并评估它们是否可以与领先的NIB和LIB竞争。最后,
