- Abstract
Abstract: The construction of hollow structures has been used as an efficient strategy to improve electrochemical properties in lithium‐ion batteries (LIBs). In this paper, novel Co2V2O7 hollow cylinders have been fabricated via a unique etching process, in which H2O2 and CO(NH2)2 were selected as the etching agent and the release rate controlling agent, respectively. The formation process for the hollow structure and the etching mechanism have been investigated. Benefiting from the improved diffusion and transport of Li+, the Co2V2O7 hollow cylinder electrode demonstrates higher electrochemical performance as an anode material for LIBs than that of Co2V2O7 solid hexagonal prisms. Under a current density of 0.4 A g−1, the cycling capacity can be improved to 2.5 times greater than that of non‐etched hexagonal prisms.
