Abstract

Li2ZnTi3O8 (LZTO) is recently considered as a promising anode material for lithium ion batteries (LIBs) due to its low cost and cycling stability. LZTO has lithiation voltage plateau at about 0.5 V vs Li/Li+ which avoids the formation of lithium dendrites. Its practical applications are limited due to its low conductivity and poor lithium ion diffusion coefficient. In order, to overcome its drawbacks many studies are undertaken such as doping with ions (Ni+2, Cu+2, Al+3, V+5), coating with conductive phases, altering morphology, and so on. In this study to overcome the drawbacks we had doped LZTO with appropriate amount of Nb+5 by simple solid-state synthesis. In particular, among the doped Li2-X NbxZnTi3O8 (x=0, 0.05, 0.1) materials, Li1.95 Nb0.05ZnTi3O8 showed narrow particle size distribution, uniform morphology, lower charge transfer resistance, highest discharge capacity, and good reversibility, making it more attractive as a potential anode electrode for commercialization.
