主　　题：N-doped carbon Layered tri-metal hydroxides Nanohybrid Hybrid battery-type asymmetric supercapacitor Coupling synergy 

摘      要：Polynary transition-metal layered hydroxides are promising energy materials owing to their unique architecture,impressive theoretical capacities,and adjustable *** the dimensional morphology and active sites/redox states are the keys to electrochemical performance *** from the reported mono-metal or binary-metal configurations,a new ternary-metal AlCoNi-LTH is coanchored onto a highly graphitized porous N-doped carbon matrix to develop superior 3D hierarchical microporous functional energy hybrids AlCoNi-LTHs/*** constructed hybrids possess superior structural durability,good electrical conductivity,and rich active sites due to the strong interfacial conjunction and favorable synergistic effect between the doped porous carbon and AlCoNi ***,the AlCoNi-LTHs/NAC hybrids demonstrate high conductivity,reasonable specific surface area,and superior specific capacitance,and the assembled hybrid battery-type supercapacitor reveals an ideal energy density of 72.6 Wh kg^(-1)at a power density of 625 W kg^(-1),which is superior to the reported *** strategy opens a platform to rationally design polynary transition-metal layered hydroxides and their hybrids for efficient supercapacitors.
