Small anatase TiO2 nanoparticles were successfully deposited on the carbon nanocage (CNC) frameworks (TiO2/CNCs) as anodes for lithium and sodium ion batteries. Due to the high specific surface area and mesopore volume of CNCs, more sites are available for depositing of TiO2 on the surface of the CNC framework. Thus, TiO2 nanoparticles were prepared with small sizes (average diameter of ~ 7 nm), leading to high specific surface area and mesopore volume of TiO2/CNCs, which enhanced storage of Li+/Na+ and shortened the diffusion path of Li+/Na+ towards high performance anodes for LIBs and SIBs with high cycle stability.
