Layered double hydroxides (LDHs) are a class of promising cathode materials for supercapacitors. However, the bad cycling performance has always been Achilles’ heel LDHs‐based In this contribution, nonelectrochemical active element Scandium (Sc) is doped into NiCo‐LDHs to greatly improve intrinsic materials. The trimetallic NiCoSc‐LDHs exhibit an ultralong cycle lifespan with 40 000 charge–discharge cycles (exceeding 50 days) and high specific capacity 196 mAh g −1 (1695 F ). Sc doping changes degradation mode from rapid decay in thousands two‐stage evolution, which consists superlong activation process about 10 then extremely slow degradation. Moreover, enhances electrochemical activity Ni 3+ , so as not only avoid its Jahn–Teller distortion, but also perform structural stabilizer alleviate local strain host layer. assembled asymmetric supercapacitor delivers 101% retention even after cycles. This work presents new pathway significantly performance, especially stability LDH‐based electrodes high‐performance
