Abstract (en)
[origin: WO2019148299A1] The present technology relates to the polymers P1: polycaprolactone-block-polytetrahydrofuran-block-polycaprolactone diacrylate and P2: polycaprolactone-block-polytetrahydrofuran-block-polycaprolactone di-2-(2-methoxyethoxy)ester for use in an electrochemical cell, in particular in electrochemical storage batteries, such as lithium batteries, sodium batteries, potassium batteries and lithium-ion batteries. More specifically, the use of these polymers as a solid polymer electrolyte (SPE), as a matrix for forming gel electrolytes or else as a binder is also envisaged.
