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.

Sulfur-containing compounds and polymers and the use thereof in electrochemical cells

Olivine-type compounds, their preparation and use in cathode materials for sodium-ion batteries. The olivine-type compounds may be obtained by a direct synthesis embodying a hydrothermal method. The method may include preparing an aqueous mixture including a M-containing compound, a M'-containing compound and a M″-containing compound to obtain a M-M′-M″ mixture; adding a P-containing compound to the mixture M-M′-M″ mixture to obtain a M-M′-M″-P mixture; adding a Na-containing compound to the M-M′-M″-P mixture to obtain a Na-M-M′-M″-P mixture; and introducing the Na-M-M′-M″-P mixture into an autoclave to perform crystal growth and obtain the compound of general formula NaMM′M″PO.
