  • Method for categorizing a battery, battery, battery recycling system, and motor vehicle
    Patent number: 11955610
    Abstract: A method to categorize a battery with respect to its further handling suitability, wherein safety-relevant and lifetime-relevant operating variables are registered for at least one battery cell of the battery in operation of the battery. By a two-operation evaluation of at least one of the operating variables and/or of a computed variable derived therefrom, a categorization variable is determined. A safety variable is derived and compared to an assigned threshold value, and in response to the threshold value or one of the possibly multiple threshold values having fallen below, a failure prognosis is prepared by the lifetime-relevant operating variables. The categorization variable is determined based on the failure prognosis.

  • Lithium-ion cell for an energy storage unit of a motor vehicle, and method for production thereof
    Patent number: 11901520
    Abstract: The invention relates to a lithium-ion cell (1) for an energy storage unit of a motor vehicle, having at least one anode (3), at least one cathode (4), an electrolyte and a separator (7) arranged between the cathode (4) and anode (3) in the electrolyte, and having a reference electrode (8) for determining a voltage potential of the lithium-ion cell (1). The reference electrode (8) is produced from lithium titanate.
