双马来酰亚胺(bismaleimides,BMI)及其寡聚物作为添加剂可提高锂离子电池的电化学性能和安全性.本文介绍了BMI的主要合成方法(二甲基甲酰胺法和丙酮法)以及一些新型的BMI单体,阐述了BMI发生聚合反应的两种机理(自由基聚合机理和迈克尔加成聚合机理),简述了近年来BMI及其寡聚物在锂离子电池中的一些应用.
Bismaleimide (BMI) and its oligomer can be used as additives for improving the performance and safety of lithium-ion batteries. This review outlines the methods of BMI synthesis and some novel structure of BMI. Two different mechanisms, free radical polymerization and Michael addition polymerization, are proposed in terms of BMI polymerization. The recent progress of BMI additives applied in lithium-ion batteries is demonstrated.
