GeO₂ microspheres/N-doped hierarchical porous carbon (NHPC) composites are solvothermally prepared and subsequent calcinated employing ginger as biotemplate. The SEM and TEM images demonstrate the GeO₂ microspheres are uniformly dispersed or embedded in NHPC matrix. Evaluating the performances of GeO₂/NHPC composites as Li-ion battery electrodes, they deliver a specific capacities of 2261.4 mA h g⁻¹ at 200 mA g⁻¹, after 100 cycles it remains a high reversible capacity of 1014.3 mA h g⁻¹ and close to 100% coulomb efficiency. The enhanced lithium storage capability is chalked up to high specific surface area and properly hierarchical porous structure of GeO₂/NHPC. The synthetic technique is a feasible and successful paradigm for other large capacity materials with large change in volume and poor electroconductivity.
