年产5000万平米聚烯烃锂电池隔膜生产工艺设计

北京理工大学珠海学院2020届本科生毕业设计Production process design of polyolefin lithium batterymembrane with an annual output of 50 million square metersAbstractThe battery separator is one of the key components in the lithiumbattery.The performance of the separator determines the structure andinternal resistance of the battery,which affects the characteristics of thebattery's capacity performance.This design uses 50 million square meters of polyolefin lithiumbattery separator annually for process design.First,it analyzes the currentproduction status of lithium battery separators.Secondly,through acomparative analysis of the currently widely used polyethylene lithiumbattery separator process route and production method,the productionprocess of wet-process polyethylene lithium battery separator is selected,and the production process,production principle,raw material formula ofthe method for producing polyethylene separator And the processconditions are described.According to the designed process route,aprocess with control points is drawn;at the same time,the balance andequipment process are calculated.Through the integration of the abovecalculation results,a reasonable factory workshop is designed,including
