Abstract
An electrode including an additive for forming pores with an average particle diameter of 1 μm or greater, and a lithium secondary battery including the electrode. The porosity of the porous particles may be from 50% to 95%. The porosity of the electrode increases by including the additive for forming pores. As the porosity of the electrode increases by the additive for forming pores, and accordingly, effects of having excellent electrode reactivity and enhanced initial capacity are obtained even under high loading.
