摘要： This invention provides a lithium secondary battery which degrades less upon high-rate charge/discharge cycles (thus durable). The lithium secondary battery comprises positive electrode 10 having positive electrode active material layer 14, negative electrode 20 having negative electrode active material layer 24, organic porous material layer 32 placed between positive electrode active material layer 14 and negative electrode active material layer 24, inorganic porous material layer 34 placed between organic porous material layer 32 and negative electrode active material layer 24. Inorganic porous material layer 34 comprises an inorganic filler that does not store lithium at a potential higher than the lithium-storing potential of the negative electrode active material layer, and a Li absorber that irreversibly stores lithium at a potential higher than the lithium-storing potential.
