Electrochemical performance of lithium titanate anode fabricated using a water-based binder

A novel anode material based on Li₄Ti₅O₁₂ prepared using the combination of poly-3,4-ethylenedioxythiophene/polystyrene sulfonate and carboxymethylcellulose for the conducting polymer binder was developed. The comparative study of this material with conventional polyvinylidene fluoride and with the conductive polymer binder by the cyclic voltammetry and galvanostatic charge–discharge methods revealed that the anode material modified with the conductive binder possesses superior properties in terms of higher specific capacity (increase up to 14%), improved high-rate capability, and life cycle stability of battery.
