Abstract

High energy density all−solid−state batteries (ASSBs) have been regarded as the most promising next generation electrochemical energy storage systems. With lithium metal selected as an ideal anode, searching for suitable cathode materials remains a tough task. Recent studies reveal that Li−rich Mn−based cathode (LRM) can deliver a higher reversible capacity compared to its counterpart in ASSBs. However, corresponding research of LRM ASSBs (LRASSBs) is still in the infant stage and some critical issues remain to be solved, such as the poor kinetics, complex and serious interfacial reactions, and unsatisfactory cyclability. Herein, a focused review is proposed, bringing in−depth understandings on the mechanisms of capacity issues of LRASSBs caused by the kinetic and interfacial problems. In addition, potential modification strategies on fully releasing the capacity superiority of LRM are proposed in various scales. Furthermore, perspectives for designing high−energy−density LRASSBs are systematically analyzed.

在全固态电池中实现高容量富锂锰基正极材料：问题与机遇

高能量密度全固态电池（assb）被认为是最有前途的下一代电化学储能系统。选择金属锂作为理想的阳极，寻找合适的阴极材料仍然是一项艰巨的任务。最近的研究表明，与assb中的同类产品相比，富Li−Mn−基阴极（LRM）可以提供更高的可逆容量。然而，LRM assb （lrassb）的相关研究仍处于起步阶段，动力学差、界面反应复杂严重、可循环性不理想等关键问题仍有待解决。在此，本文重点综述了由动力学和界面问题引起的lrassb容量问题的机理。并在不同尺度上提出了充分释放LRM容量优势的潜在修正策略。此外，还系统地分析了高能量密度lrassb的设计前景。
