Although Li-ion batteries have emerged as the battery of choice for electric vehicles and large-scale smart grids, significant research efforts are devoted to identifying materials that offer higher energy density, longer cycle life, lower cost, and/or improved safety compared to those of conventional Li-ion batteries based on intercalation electrodes. By moving beyond intercalation chemistry, gravimetric capacities that are 2-5 times higher than that of conventional intercalation materials (, LiCoO and graphite) can be achieved. The transition to higher-capacity electrode materials in commercial applications is complicated by several factors. This Review highlights the developments of electrode materials and characterization tools for rechargeable lithium-ion batteries, with a focus on the structural and electrochemical degradation mechanisms that plague these systems.
尽管锂离子电池已成为电动汽车和大规模智能电网的首选电池，但仍投入了大量研究工作来寻找与基于插层电极的传统锂离子电池相比，具有更高能量密度、更长循环寿命、更低成本和/或更高安全性的材料。通过超越插层化学，可以实现比传统插层材料（如LiCoO和石墨）高2至5倍的重量容量。在商业应用中向高容量电极材料的转变受到几个因素的影响。本综述重点介绍了可充电锂离子电池电极材料和表征工具的发展，重点关注困扰这些系统的结构和电化学降解机制。
