摘要: The present invention belongs to the technical fields of macromolecular materials and batteries, and particularly relates to a non-porous separator and the use thereof, more particularly to a non-porous separator having a gelation function and the use thereof. This non-porous separator is composed of two or more macromolecular materials, wherein at least one of the macromolecular materials can be gelled by an organic solvent. This non-porous separator can be used in batteries having an organic solvent-based electrolyte and a high energy density, such that not only can a micro-short circuit, generated due to the introduction of foreign matters such as metals, be prevented, leading to an improved qualification rate for the product, but also the safety performance and the cycle life of such a battery can be improved significantly.
