Calcium (Ca)-based batteries are appealing because Ca is abundant, but their development is extremely challenging. Recently in Nature Chemistry, Cheng and coworkers reported a Ca-ion battery (CIB) system that comprises an intercalation cathode and an alloy anode and exhibits high voltage, excellent reversibility, and reasonable cycling performance.

迈向可逆的室温钙离子电池

钙（Ca）基电池之所以吸引人，是因为Ca含量丰富，但其开发却极具挑战性。Cheng和他的同事们最近在《自然化学》杂志上报道了一种Ca-离子电池（CIB）系统，该系统包括一个嵌入阴极和一个合金阳极，并具有高电压，出色的可逆性和合理的循环性能。
