Abstract

Solid state electrochemical energy storage devices such as all solid state batteries and supercapacitors have attracted huge attention to replace the traditional aprotic liquid electrolyte based electrochemical energy storage systems. Since aprotic liquid based devices suffer from operational safety issues, inferior electrochemical cycling/energy densities and long term system stability. Recent improvements in all solid state devices have brought these energy storage systems very close to widespread commercialization. However, numerous challenges including effective contact formation at electrode/electrolyte interface, poor ionic conductivity of solid electrolytes (10–5–10–3 S cm−1) compared to those of commercially used liquid electrolytes (10−2 S cm−1 commonly organic liquids) and lack in understanding of interfacial processes during charge-discharge of electrochemical devices, limit their wider application commercially. In this article author will endeavor to review conventional liquid based electrolytes including aqueous, organic and room temperature ionic liquids as well as recent developments in solid state electrolytes consisting of organic polymer based and inorganic solid state electrolytes will be discussed in detail. Author will also attempt to elucidate the fundamentals behind the ion-conduction mechanism of solid state electrolytes and the effect of electrode/electrolyte contact at the interface on the performance of electrochemical device will also be elaborated. Future research direction due to the rise of these challenges will also be deliberated in order to further improve the performance of these electrical energy storage system to make these solid state devices as commercial reality.
