Abstract Li-ion batteries are extensively used in portable electronics due to high energy, power density and superior electrochemical performance. For this, Li4Ti5O12 a zero strain anode material with excellent reversibility for the Li-ion insertion and de-insertion and flat potential plateau, serves as an ideal anode material. However, it has low conductivity which hampers its commercialization. In the present work, Li4Ti5O12 is prepared by sol-gel method. It’s structural analysis confirms the formation of nanoparticles with uniformly aligned grains and exhibits high discharge capacity of 181 mA.h/g at 0.1 C. It is the synergetic effect of nanoparticles size and surface area, which imparts it the outstanding electrochemical performance in terms of long term stability and charge storage capacity.
