Abstract:Polyhedral oligomeric silsesquioxane (POSS) is a silicone compound with unique structure. POSS-based polymer (POSS-polymer) attracts much attention due to its unique electrochemical and mechanical properties. Polymer electrolyte materials with high ionic conductivity, suitable mechanical properties, and stable chemical and electrochemical properties play an important role in developing batteries with high qualities. POSS-polymer can improve the thermal stability and mechanical properties, further enhance the ionic conductivity of polymer electrolyte, and accordingly it is considered as one of the most promising candidates for the future electrolyte materials of lithium ion batteries. Additionally, with a little addition of POSS in the polymer electrolytes, better battery charge/discharge performance can be achieved. This review was intended to cover the more recent advances in structure-property relationships of POSS-polymers. An application prospect of POSS-polymers in lithium ion batteries was also proposed.
Key words: POSS-polymers; lithium-ion batteries; polyelectrolyte
