Abstract
Disclosed is a lithium battery, including a positive electrode plate, a negative electrode plate, and a polyolefin separator disposed therebetween. An organic-inorganic hybrid film disposed between the polyolefin separator and the positive electrode plate, and/or disposed between the polyolefin separator and the negative electrode plate. The organic-inorganic hybrid film includes inorganic oxide particles and a fluorinated polymer binder, wherein the inorganic oxide particles and the fluorinated polymer binder have a weight ratio of about 40:60 to 80:20.
