Patent ID: 11959664

Abstract:
The invention proposes a method and a device (110) for thermal-electrochemical energy storage and energy provision. The device (110) comprises: at least one thermal energy store (118), wherein the thermal energy store (118) comprises at least one heat transport medium (121) and at least one storage medium (119) selected from the group consisting of: an electromagnetic storage medium, a thermal storage medium; at least one heating device (134), wherein the heating device (134) is designed to receive the heat transport medium (121) from the thermal energy store (118), to heat this medium and return it to the thermal energy store (118); at least one electrochemical cell (146), wherein the electrochemical cell (146) comprises at least one gas chamber (148), wherein the electrochemical cell (146) further comprises at least one first electrode (150) and at least one second electrode (152): wherein the second electrode (152) is designed as a 3-phase electrode (154), wherein the 3-phase electrode (154) has at least one first phase boundary (156) to the gas chamber (148) and at least one second phase boundary (158) to the electrochemical storage medium (119); wherein the electrochemical cell (146) is designed to electrochemically react the electrochemical storage medium (119); and at least one container (160), wherein the container (160) is designed to receive a supply on the heat transport medium (119), wherein the container (160) is further designed to receive the thermal storage medium (119) from the thermal energy store (118).
