Functional lithium battery diaphragm slurry, functional lithium battery diaphragm and lithium battery

The functional lithium battery diaphragm slurry is prepared from the following raw materials in parts by mass: 5-10 parts of polystyrene butadiene emulsion, 5-7 parts of PVDF powder, 1-3 parts of a dispersing agent, 50-100 parts of a thickening agent, 1-10 parts of a binding agent and 50-100 parts of deionized water. By adding the polystyrene butadiene emulsion, the binding power between the lithium battery diaphragm and the battery negative electrode is effectively improved, and the cycle life of the lithium battery is prolonged. 本发明公开了一种功能性锂电池隔膜浆料，其原料按照质量质量份数包括：聚苯乙烯丁二烯乳液5-10质量份、PVDF粉体5-7质量份、分散剂1-3质量份、增稠剂50-100质量份、粘结剂1-10质量份和去离子水50-100质量份。通过聚苯乙烯丁二烯乳液的加入，有效提高锂电池隔膜与电池负极之间的粘结力，提高锂电池的循环寿命。
