Self-sacrifice template construction of a conductive Cu 3 (HHTP) 2 nanowhisker arrays@copper foam toward robust lithium storage

Nanowhisker-like Cu (HHTP) composed of neat arrays grown on a copper foam is rationally designed and prepared using Cu(OH) nanowire arrays as a self-sacrifice template. Benefiting from the good conductivity of Cu (HHTP) and an ordered array structure, the optimized Cu (HHTP) @CF-3 electrode exhibits high area capacity, good rate performance and cyclic stability.
