Enhanced electrochemical performance of MoS2 anode material with novel composite binder

Abstract

A simple and green approach for creating a highly capacitive molybdenum disulphide (MoS2) anode material for lithium-ion batteries is proposed. The electrode composition consists of MoS2 and conductive water-based binder PEDOT:PSS/CMC (poly(3,4-ethylenedioxythiophene)/poly(styrenesulphonate)/carboxymethyl cellulose). The electrochemical performance of modified electrodes is markedly superior to those with conventional PVDF (polyvinylidene fluoride) and carbon black composition. The electrode provides initial capacity of 1090 mA h g−1 at 0.1 mA g−1, maintains 410 mA h g−1 at 2 mA g−1 and retains 78% of initial capacity after 100 charge-discharge cycles.
