Lithium Borate

We prepared a solid polymer electrolyte (SPE) composed of a lithium borate salt and a polymer matrix, which can be employed for all-solid-state lithium-ion batteries. The lithium borate salt was made from lithium cations and bis (maleic acid) borate anions, and exhibits an excellent thermal stability as well as high ionic conductivity. The polymer matrix is an amorphous polymeric material having no crystalline regions, which is beneficial for the movement of lithium ions in the SPE. The polymer matrix also has good mechanical performance and thermal stability. Moreover, the SPE also has a relatively high ionic conductivity.
