Patent number: 10777852Abstract: 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.Type: GrantFiled: March 30, 2018Date of Patent: September 15, 2020Assignees: 24M Technologies, Inc., Kyocera CorporationInventors: William Henry Woodford, Naoki Ota, Takaaki Fukushima, Jeffry Disko, Junzheng Chen
