A small polypropylene lithium battery diaphragm simulation production equipment

Abstract

This invention relates to the field of special materials for polypropylene lithium battery diaphragms, in particular to a small polypropylene lithium battery diaphragm simulation production device. Asmall casting machine and a universal tensile testing machine are included, and the universal tensile testing machine is fixedly arranged at one end of the small casting machine; the end, away from the universal tensile testing machine, of the small casting machine is fixedly provided with a material entering pipe; the end, close to the material entering pipe, of the inner side of the small casting machine is fixedly provided with an extruding machine; a discharging port is fixedly formed in the lower end of the extruding machine; the lower end of the discharging port is movably provided witha first conveying belt through a rotating shaft; the end, away from the material entering pipe, of the extruding machine is fixedly provided with a telescopic rod; and a tool bit is fixedly arranged at the lower end of the telescopic rod. According to the small polypropylene lithium battery diaphragm simulation production device, by arranging the small casting machine and the universal tensile testing machine, firstly simulation production is performed on materials needed for producing a diaphragm, then the diaphragm after being produced is detected, and batch production can be performed if noproblems exist, so that resources needed for production can be saved.

Description

technical field [0001] The invention belongs to the field of special materials for diaphragms of polypropylene lithium batteries, in particular to a simulated production equipment for diaphragms of small polypropylene lithium batteries. Background technique [0002] In the structure of lithium batteries, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure, internal resistance, etc. of the battery, which directly affects the capacity, cycle and safety performance of the battery. A diaphragm with excellent performance is of great importance to improve the performance of the battery. The comprehensive performance plays an important role. Most of the existing diaphragm materials are polypropylene materials. During the research and development process of polypropylene lithium battery diaphragm special materials, it is necessary to conduct production tests on special materials to judge whether the special materials m...
