One pathway to higher energy density batteries is by way of intercalation cathodes that operate at high voltage, storing charge on both the oxide and transition metal ions. In the January 23, 2020 issue of Nature, Peter Bruce and colleagues illuminate the mechanism by which the honeycomb superstructure of most O-redox compounds is lost, along with the high energy density, upon first-cycle charging. The secret of certain intercalation compounds maintaining the desired high-voltage electrochemistry upon cycling is in their unique superstructures that resist molecular O₂ formation.

走向高能电池：通过上层结构控制实现高电压稳定性

通往更高能量密度电池的一种途径是通过在高电压下工作的嵌入阴极将电荷存储在氧化物和过渡金属离子上。在2020年1月23日出版的《自然》杂志上，彼得·布鲁斯和他的同事阐述了第一循环充电时，大多数O-氧化还原化合物的蜂窝状上部结构以及高能量密度损失的机理。某些插层化合物在循环时保持所需的高压电化学的秘密在于其独特的抵抗分子O ₂形成的上层结构。
