Lithium-ion batteries have attracted widespread public attention because of their excellent energy density and extremely long cycle stability. Metal oxide has been widely used in lithium ion batteries as high-capacity anode materials. However, due to the serious volume expansion effect of metal oxide in the process of lithium removal, the cycle stability and multiplier performance of the battery are very poor. The unique structure of two-dimensional materials can give excellent performance to composite materials by improving the electrical performance of lithium metal oxides. In this paper, a flexible nitrogen-doped carbon-coated garnet-like cluster CoOx was designed by calcination in air using a polyaniline-coated metal-organic framework MOF/ GO as a precursor and loaded on a three-dimensional (3D) graphene skeleton composite (NC@CoOx@GF). This MOF extension-transformed anode material is protected by a pomegranate-like NC@CoOx carbon cluster and a robust 3D graphene skeleton, offering promising prospects for high-performance cathode.
