Abstract :
In order to achieve the higher energy density in lithium-ion and lithium-metal batteries, the use of electrolytes with desirable properties is a key factor. However, it is necessary to reduce or eliminate the disadvantages of conventional electrolytes such as irreversible decompositions and uncontrolled interfacial reactions, leading to the higher performance and safety of batteries. In this regard, the use of polymeric organosilicon compounds in electrolytes is of great industrial interests due to favorable properties such as non-toxicity, easy chemical modification, non-flammability, low glass transition temperature, high chemical and thermal stability and lower vapor pressure compared to traditional electrolytes. Accordingly, in the last decade, several efforts have been made to improve and develop the performance of polymeric electrolytes based on organosilicon compounds. This paper reviews recent developments in the field of properties and performance of polymeric electrolytes based on organosilicones for use as liquid, gel or solid state electrolytes in lithium-ion and lithium-metal batteries. Different types of polymeric electrolytes based on organosilicon compounds such as polysiloxane and polyhedral oligomeric silsesquioxanes were discussed from the point of view of the role of molecular structure in ionic conductivity, thermal stability, chemical and electrochemical stability, as well as the safety of the respective batteries.
