Review on the recent progress in the nanocomposite polymer electrolytes on the performance of lithium-ion batteries

Abstract

In the recent decade, lithium-ion batteries have flourished in the mobile market to a greater extent. Despite its versatile commercial applications in various fields, it faces critical issues that restrict by safety concerns including leakage, combusting, or even explosions because of the low boiling point of liquid organic electrolytes. In order to mitigate these difficulties, solid electrolytes can be a potential choice. Polymer-based solid Li-ion batteries have been attracting researchers for accomplishing high performance. However, poor mechanical strength and low transport of Li+ ions inside the cell remain prominent challenges for its commercialization. To solve these issues and enhance the overall performance, polymer-based nanocomposite electrolytes developed by incorporating the nanofillers into the polymer matrix have been investigated to a greater extent. This review briefly elaborates on the recent progress of polymer nanocomposite electrolytes for lithium-ion batteries, factors affecting its performance, and various models used in the interpretation of its performance.
