Abstract: A separator 4 for a lithium secondary battery includes a porous film 12 including a polyolefin layer 16 and a lubricant layer 14 disposed on a surface of the porous film 12. The lubricant layer 14 includes a particulate substance 22 and has a three-dimensional surface roughness of 0.15 to 1.45 ?m. The particulate substance 22 can adhere to the surface of the porous film 12 by electrostatic attraction. The porous film 12 can further include a heat-resistant porous layer 18 between the polyolefin layer 16 and the lubricant layer 14. The separator 4 allows a winding core for the lithium secondary battery to be pulled out smoothly.

Abstract: The present invention relates to a solid electrolyte including Li, O, P and a transition metal element. In the solid electrolyte, because the transition metal element T is reduced prior to phosphorus atoms, it is possible to prevent the valence of phosphorus atoms from decreasing. Thereby, the decomposition of the solid electrolyte resulting from the decrease of valence of phosphorus atoms is prevented, and therefore high ion conductivity is retained even in a wet atmosphere.
