Secondary Batteries - Lithium Rechargeable Systems | Electrolytes: Single Lithium Ion Conducting Polymers

High Li ⁺ transference number, high total ionic conductivity, and fast kinetics of ion transport across the cathode-electrolyte and anode-electrolyte interfaces are equally important for successful operation of lithium and lithium-ion batteries, comprising solid polymer electrolytes. The overview presents recent achievements in the development of single-cation-conducting solid polymer electrolytes, which include polyanionic membranes, amorphous composite organic/inorganic systems, and ordered decoupled electrolytes. The use of such polymer electrolytes confers substantial improvement in the utilization of cathode-active material and improved peak power at high discharge rate and pulsed current applications.
