Summary: A novel strategy was developed to prepare pomegranate-inspired nanospheres in which ultrafine Zn2Ti3O8/TiO2 nanoparticles are embedded in a hierarchical carbon framework (Zn2Ti3O8/TiO2@C). This structure effectively reduces Li+ diffusion distance, relieves volume expansion, and induces additional pseudocapacitive effect, leading to a high capacity and remarkable cycling life of the Zn2Ti3O8/TiO2@C electrode. This work provides beneficial enlightenment for novel material structure design and accelerates the application of Zn2Ti3O8 in lithium-ion batteries.

Summary: Ga2O3 is widely used as anode material for lithium-ion batteries due to its high theoretical capacity. However, it has limited electronic conductivity and severe volume expansion, which restrict its application. In this study, Ga2O3 nanospheres were coated with carbon to improve overall electrochemical performance. The carbon coating treatment not only shortened ion transmission path and improved cycle stability but also provided abundant lithium-ion storage space, resulting in high pseudocapacitive storage characteristics.
