AI Technical Summary
Technical Problem
Traditional battery separators are prone to melting or rupture under extreme conditions, leading to short circuits and posing safety hazards.
Method used
The design employs a composite structure consisting of a frame, reinforcing ribs, an inner fiberglass board, a base plate, an outer fiberglass board, and a puncture-resistant panel. Combined with the design of protrusions, this enhances the rigidity and puncture resistance of the partition. High-polymer materials are selected to ensure chemical stability and wear resistance.
Benefits of technology
This achieves high strength, high rigidity, and high puncture resistance in the separator, improving battery safety and lifespan.

Abstract
Transverse ribs and vertical ribs are arranged in a plate frame, latticed reinforcing ribs are formed by the transverse ribs and the vertical ribs, an inner-layer glass fiber plate is arranged on each of two sides of each reinforcing rib, a base plate is arranged on the outer side of each inner-layer glass fiber plate, an outer-layer glass fiber plate is arranged on the outer side of each base plate, a stab-proof panel is arranged on the outer side of each outer-layer glass fiber plate, and the stab-proof panel is arranged on the outer side of each outer-layer glass fiber plate. Four edges of the inner-layer glass fiber plate, the base plate, the outer-layer glass fiber plate and the puncture-proof panel are fixedly connected with the plate frame; protruding blocks are arranged on the inner side of the inner-layer glass fiber plate in an array mode. By means of the composite structure design, high strength, high rigidity and high puncture resistance of the partition plate are achieved. Meanwhile, the overall rigidity and puncture resistance of the partition plate are further enhanced through the design of the protruding blocks, and in addition, the chemical stability and wear resistance of the partition plate are guaranteed through material selection of the base plate and the puncture-proof face plate.
