设计了一种具有超薄离子交换层的复合膜，作为锰基正极材料锂离子电池的隔膜。复合膜具有源自离子交换过程的Mn2+捕获功能，特别是在高温下，并被证明有助于有效缓解锂离子电池的容量衰减。复合膜的热稳定性增强，润湿性改善，锂离子转移数增加，进一步表明复合膜在锂离子电池中的应用前景广阔。
A composite membrane with an ultra-thin ion exchangeable layer is specially designed as a separator in lithium ion batteries with manganese-based cathode materials. The composite membrane features a Mn2+ capture function which originates from the ion exchanging process, especially at high temperature, and is proven to help to alleviate the capacity decay of lithium ion batteries effectively. The enhanced thermal stability, improved wettability and higher lithium ion transference number of the composite membrane further suggest its promising application in lithium ion batteries.
