摘要： The present invention generally relates to energy storage devices, and to metal sulfide energy storage devices in particular. Some aspects of the invention relate to energy storage devices comprising at least one flowable electrode, wherein the flowable electrode comprises an electroactive metal sulfide material suspended and/or dissolved in a carrier fluid. In some embodiments, the flowable electrode further comprises a plurality of electronically conductive particles suspended and/or dissolved in the carrier fluid, wherein the electronically conductive particles form a percolating conductive network. An energy storage device comprising a flowable electrode comprising a metal sulfide electroactive material and a percolating conductive network may advantageously exhibit, upon reversible cycling, higher energy densities and specific capacities than conventional energy storage devices.

摘要： A battery system includes a main electrochemical cell that includes a cathode and an anode, a cathode tab electrically coupled to the cathode, and an anode tab electrically coupled to the anode. A second electrochemical cell is electrically coupled to the cathode tab and the anode tab. An interrupt device, such as a bi-stable metal disc, is operably coupled to the second electrochemical cell and at least one of the cathode tab or the anode tab. Upon overcharging of the main electrochemical cell, the voltage between the cathode tab and the anode tab causes the second electrochemical cell to generate gases that triggers the interrupt device, which in turn disconnects at least one of the cathode tab or the anode tab, thereby protecting the main electrochemical cell from further damages.
