Abstract Searching for low‐cost, high‐capacity, high‐power, high‐stability, high‐tap‐density, and inherently safe materials developing cheap, safe, high‐performance batteries has always been a research hotspot. Herein, an low‐strain KTiOPO 4 (KTOP) submicron single crystals with uniform thin layer carbon coating are developed using ball‐mill assisted solid‐state method. Uniform solid electrolyte interphase, coating, stable structure synergistically help compact KTOP achieve exceptional anodic K‐ion storage performance. The carbon‐coated obtained under the carbonization temperature of 400°C (KTOP‐C‐400) can deliver potassium ion performance 253.3, 224.0, 175.5, 131.1 mA h g −1 at current density 100, 200, 500, 1000 , respectively, in 5 M bis(fluorosulfonyl)imide (KFSI) DIGLYME electrolytes. Even after being cycled cycles, capacity was maintained 182.5 coulombic efficiency 99.9%.
