sodium-ion batteries

The use of solid polymer electrolytes is a novel and promising approach for enhancing the safety of lithium-ion and sodium-ion batteries. A number of publications on manufacturing electrolytes with lithium-ion and sodium-ion conductivity based on Nafion-like polymers have appeared in recent decade. The present mini-review analyses various methods of the synthesis of such electrolytes and their properties, as well as the information on laboratory lithium-ion and sodium-ion batteries using such electrolytes.

The critical analysis of literature of last 15 years, concerning solid polymer electrolytes with Na⁺-ion-conductivity is presented. True polymer electrolytes as well as gel-polymer electrolytes based on polyethylene oxide, polyacrylonitrile, polyvinyl alcohol, polyvinyl chloride, polyvinyl pyrrolidone, PVdF–HFP, PMMA, Nafion are reviewed. Special attention is paid for temperature dependence of conductivity.
