Abstract
- The porous erythrocyte-like CuCo<subscript>2</subscript>O<subscript>4</subscript> was first prepared in this work by a convenient solvothermal post-calcination method used polyvinylpyrrolidone (PVP) as structure-directing agent and ethanol as solvent. When used as anode active materials of Li-ion batteries (LIBs), that 973 Ah/kg of reversible capacity and above 98% of coulombic efficiencies were made by the porous erythrocyte-like CuCo<subscript>2</subscript>O<subscript>4</subscript> at 0.5 A/g of current density over 300 times. And cycling at 0.1 A/g of current density the starting specific discharge and charge capacities were 1428 and 1052 Ah/kg higher than theoretical capacity. Excellent cycling performance kept 96% of the reversible capacity retention. The superior rate performances were made at 0.1, 0.2, 0.5, 1, 2 and 0.1 A/g of current densities for 15 times. These exceptional electrochemical performances are all related to its particular compacted morphology and mesoporous spinel structure. [ABSTRACT FROM AUTHOR]
