ABSTRACT

Batteries are electrochemical storage systems that are basically comprised of three components: an anode, a cathode, and an electrolyte. The performance of lithium ion batteries (LIBs) greatly depends on the electrochemical reactions taking place in the electrolyte; hence, electrolytes are the critical component for high-performance LIBs with a long lifetime. Based on their physical properties, electrolytes for LIBs are classified as solid, liquid, and gel electrolytes, each having its own advantages and limitations. Depending on the matrix system, solid electrolytes are classified as ceramic electrolytes and polymer electrolytes (PEs). Compared to ceramic solid electrolytes, PEs has higher ionic conductivity, is easy to process, and is flexible. Carbon nanotubes is an allotrope of carbon with unique structural features and has a large aspect ratio, high strength, and modulus, making it an excellent reinforcing agent for a polymer matrix. In PEs, the polymer materials act as a host matrix that is activated by conventional liquid electrolyte.
