摘要： The present technology relates to a sulfur-containing polymer or organic compound for use in a positive electrode material, especially in lithium batteries. More specifically, the use of this sulfur-containing polymer or compound as an active electrode material makes it possible to combine sulfur and an active organic cathode material. The present technology also relates to the use of the sulfur-containing polymer or organic compound as defined herein as a solid polymer electrolyte (SPE) or as an additive for electrolyte, especially in lithium batteries.

摘要： 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.
