Li2ZnTi3O8/C nanomaterials are synthesized using the sol-gel method; polyvinylidene fluoride (PVDF) and sucrose are used as carbon sources. The materials are characterized using XRD, TEM, TGA, and Raman spectroscopy. The influence of the carbon precursor and the annealing temperature on the electrochemical properties of the materials is investigated. It has been shown that the addition of both polyvinylidene fluoride and sucrose leads to the formation of nanosized lithium zinc titanate and high conductive carbon. This modification leads to the enhancement of electrochemical properties of the materials; namely, the discharge capacity of Li2ZnTi3O8 and Li2ZnTi3O8/C-5F annealed at 800°C under a current of 20 mA/g are 180 and 227 mA h/g, respectively.
