Abstract :
Lithium batteries as one of the most advanced rechargeable batteries are used in various applications today. Electrolytes are one of the main components of lithium batteries and are divided into different types such as liquid electrolyte, solid electrolyte, and polymer electrolyte. Polymer electrolytes, as one of the main components of these batteries, are a suitable alternative to solve the safety problems of liquid electrolytes. As a result, using polymer electrolytes increases battery life. However, these electrolytes have disadvantages such as lithium-ion transfer number low ionic conductivity, and poor compatibility with electrodes. One of the solutions to solve the mentioned challenges is to use polymer electrolytes with the ability to transfer single ions. Polymer electrolytes with the ability to transfer single ions consist of a polymer backbone with side branches containing anionic functional groups that facilitate the free movement of lithium ions. Single-ion conductive electrolytes can be divided into different types such as materials based on sulfonyl imide, carboxylate, sulfonate, boron, and polyurethane materials. The use of these electrolytes is considered an effective and desirable way to increase the lifespan of batteries. Due to the importance of this issue, this research will review polymer electrolytes with the ability to transfer single ions used in the next generations of lithium batteries.
