Patent ID: 7687201

Claim:
A lithium secondary battery comprising an anode mix including a silicon- or tin-based active material as an anode active material and a thermosetting material and a curing agent as a binder, wherein a binding force between the anode active material and between the anode active material and a current collector is secured by applying the anode mix to a current collector and heating to cure the anode mix applied to the current collector, wherein the anode mix further includes a curing accelerator, and the anode mix is applied to the current collector and heat-cured at a temperature of less than 200° C., and wherein the curing accelerator is added in a catalytic amount, and is 2-ethyl-4-methylimidazole, 1-(2-cyanoethyl)-2-alkyl imidazole or 2-phenylimidazole.
