A flower‐like α‐phase nickel‐cobalt‐manganese hydroxide modified with two‐dimensional Ti3C2 for high performance hybrid supercapacitors

Abstract A flower‐like nickel‐cobalt‐manganese hydroxide (NiCoMn‐OH) modified with two‐dimensional Ti3C2 nanoflakes has been synthesized via simple one‐step hydrothermal method. The NiCoMn‐OH/Ti3C2 composite exhibits a high specific capacity of 670.3 C/g at a specific current of 1 A/g, higher than 6...
