The significance of fillers in composite polymer electrolytes for optimizing lithium battery

Solid polymer electrolytes constructed from polymers have high safety, outstanding thermal stability, and minimal flammability as their merits. Many researchers have been working on creating high-performance Li-based batteries composed of solid polymers. Composite polymer electrolyte (CPEs) electrochemical characteristics, which might include conductivity of ions, ion transfer numbers, and electrochemical durability, play an essential role when assessing the performance of energy conservation and conversion systems. Inorganic additions may enhance ionic conductivity by producing an ion transport percolation network. Additionally, the most effective filler composition can improve CPE electrochemical process stability, diminishing adverse responses and deterioration throughout gadget operations. In this article, we talk about active filler-based composites of polymers that make excellent solid electrolytes for the large-scale production of solid-state battery packs. We review the analysis and performance of active filler-based composite polymer electrolytes and look into the design of high-performance composite electrolytes.
