The designing of high voltage cathode materials is critical for the advancement 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 highest on record (beyond 4 V versus K+/K) layered materials. This work will allow further development of, particularly, cathodes K-ion
