Abstract
The present technology relates to a polymer comprising at least one ester repeating unit and one ether repeating unit for use in an electrochemical cell, particularly in electrochemical accumulators such as lithium batteries, sodium batteries, potassium batteries and lithium-ion batteries. More specifically, the use of this polymer as a solid polymer electrolyte (SPE), as a matrix for forming gel electrolytes, or as a binder in an electrode material are also contemplated.
