WIPO Patent Application WO/2018/020896
Kind Code:
A1
Abstract:
According to the present invention, a positive electrode of a lithium secondary battery is provided with an insulating tape that covers an electrode tab on an exposed part. This insulating tape has a multilayer structure that is composed of an organic material layer, a composite material layer which is formed from an organic material and an inorganic material, and an adhesive layer. The inorganic material in the composite material layer accounts for 20% or more of the weight of the composite material layer; and the inorganic material contains at least one substance selected from the group consisting of metal oxides, metal nitrides, metal fluorides and metal carbides. Puncture strength is ensured by means of the organic material layer, while heat resistance is ensured by means of the composite material layer.
