Abstract
The present invention provides a lithium secondary battery having high-capacity as well as good cycle characteristics. The lithium secondary battery includes a positive electrode comprising a positive active material, a negative electrode comprising a negative active material and an electrolyte. The negative active material includes graphite particles combined to Si particulate. The electrolyte includes a solvent, a polyether modified silicone oil where a linear polyether chain is linked to a polysiloxane chain, and a solute comprising a lithium salt.
