  • Patent number: 11848428
    Abstract: A lithium ion battery is provided that includes: a positive electrode; a negative electrode; a separator comprising a material having a melt temperature of greater than 150° C.; and an electrolyte including an organic solvent and a lithium salt. A method for sterilizing a lithium ion battery is also provided that includes: providing a lithium ion battery (particularly one as described herein); either charging or discharging the battery to a state of charge (SOC) of 20% to 100%; and steam sterilizing the battery to form a sterilized lithium ion battery.
    Type: Grant
    Filed: January 6, 2023
    Date of Patent: December 19, 2023
    Assignee: Medtronic, Inc.
    Inventors: Laura E. McCalla, Gaurav Jain
  • Patent number: 11762031
    Abstract: An electrochemical cell charging apparatus includes a charger to charge one or more electrochemical cells and a computing apparatus. The computing apparatus includes one or more processors and is operatively coupled to the charger. The computing apparatus is configured to charge an electrochemical cell using the charger, determine one or more indicators of the state of health of the electrochemical cell, and determine the state of health of the electrochemical cell based on the determined one or more indicators.

  • Publication number: 20220209311
    Abstract: At least one electrochemical cell is charged to a predetermined voltage of the electrochemical cell using an external power source. A charging current of the at least one electrochemical cell is monitored. An increase in the charging current is detected at the predetermined voltage of the at least one electrochemical cell. It is determined that the at least one electrochemical cell is in danger of experiencing a performance decrease based on the detected increase in the charging current.
