Abstract
A lithium secondary battery comprising a cathode, an anode, and an elastic composite separator disposed between the cathode and the anode, wherein the elastic composite separator comprises a high-elasticity polymer and from 1% to 99% by weight of particles of an inorganic solid electrolyte and the particles are dispersed in or bonded by the high-elasticity polymer, wherein the elastic composite separator has a thickness from 50 nm to 100 μm and a lithium ion conductivity from 10−8 S/cm to 5×10−2 S/cm at room temperature and the high elasticity polymer has a fully recoverable tensile strain from 2% to 1,000% when measured without any additive dispersed therein.
