Regulating Ni contents by a cobalt doping strategy in ternary NiCoAl-LDH nanoflowers for high-performance charge storage.

NiAl-LDH and CoAl-LDH as typical two-dimensional layered materials have been widely used as supercapacitor cathodes due to their special composition, morphology and rich electrochemically active centers. However, a clear strategy to enhance their electrochemical performances remains lacking. Here, with NiCoAl-LDHs ( = 1, 1.
