The present application provides a porous membrane and a lithium ion battery. The porous membrane provided by the present application has excellent adhesion, and at the same time, the pore structure of the porous membrane can still be well maintained after being soaked in the electrolyte, thereby reducing the probability of pore blocking in the porous membrane and making the lithium-ion battery have high performance. The ion conductivity greatly improves the kinetic performance of the lithium-ion battery, and the provided lithium-ion battery has excellent rate performance and cycle performance. |
