The designing of high voltage cathode materials is critical for the advancement of potassium-ion (K-ion) battery. Herein, we present a new honeycomb framework P2-type K2/3Ni1/3Co1/3Te1/3O2 (or equivalently written as K2NiCoTeO6) which exhibits the highest voltage on record (beyond 4 V versus K+/K) for layered cathode materials. This work will allow for the further development of, particularly, high voltage layered cathodes for K-ion battery.
高压阴极材料的设计对于钾离子（K-ion）电池的发展至关重要。在此，我们提出了一种新的蜂窝状框架 P2 型 K2/3Ni1/3Co1/3Te1/3O2（或等效地表示为 K2NiCoTeO6），其对于层状阴极材料表现出创纪录的最高电压（相对于 K+/K 超过 4 V）。这项工作将特别允许进一步开发高压层状阴极用于 K 离子电池。
