Smart electronics and wearable devices need better batteries that are safer, more flexible, and can hold more energy, but current Li-based rechargeable batteries (LBRBs) face limitations due to their liquid electrolytes.
Solid polymer electrolytes (SPEs) are proposed as a solution, but they currently have low lithium conductivity and transference, making them still early in development for room temperature applications.
The paper discusses how lithium conduction works in SPEs, strategies to enhance their performance, and some promising applications that highlight the benefits of using SPEs in advanced battery technologies.
