Abstract
A simple approach to improve the initial charge/discharge behavior of natural graphite is described. Graphite modified by adsorption or adhesion of polydimethylsiloxane is used as an intercalating anode for lithium-ion batteries. The modified graphite electrode shows ∼14% reduction in the first irreversible capacity while the reversible capacity remains unchanged in comparison with a bare graphite electrode. In addition, the chemical modification also improves the cycling performance of the graphite electrode.
