Lithium-Ion Battery Separator

Product Overview
The lithium-ion battery separator is a key component in the structure of the battery, providing essential electrical isolation. It separates the positive and negative electrodes of the battery to prevent direct contact, which could lead to short circuits, effectively blocking the flow of current and ensuring the battery's safety. Additionally, the separator helps prevent the battery from overheating, enhancing the stability and safety of lithium batteries. Lithium-ion battery separators are mainly divided into dry-process single-laminated separators and wet-process separators, widely used in power batteries, energy storage batteries, and consumer lithium batteries.
