Here, this review presents recent progress in Li-ion and Li-S battery separators, with a focus on polymer, ceramic, and nanocarbon separators with the goal to provide materials selection principles.
Review of Progress in the Application of Polytetrafluoroethylene-Based Battery Separators Batteries have broad application prospects in the aerospace, military, automotive, and medical fields. The performance of the battery separator, a key component of rechargeable batteries, is inextricably linked to the quality of the batteries.
To summarize, proper parameters need to be designed for separators to significantly promote electrochemical performance under the premise that the batteries are safe and reliable. And on this basis, new materials and new manufacturing technologies need to be developed to speed up the evolution of next-generation lithium-based batteries. 4.
However, such thick separators come at the expense of less free space for accommodating active materials inside the battery, thus impeding further development of next-generation lithium-based batteries with high energy density.
Therefore, the two safety guarantee properties of the composite separator greatly enhance the safety and service life of the battery, which allows the application of lithium batteries to be further improved in the application scenario and application scale.
Thin separators with robust mechanical strength are undoubtedly prime choice to make lithium-based batteries more reliable and safer.
