  • Patent number: 10921383
    Abstract: A battery diagnostic system stores capacity degradation models for batteries of a specific type mapped to sets of battery cycle models formed by voltages and/or currents measured at different capacities. Each capacity degradation model is mapped to a set of battery cycle models associated with different battery capacities. The system, upon accepting measurements indicative of a battery cycle and a current capacity of the test battery, compares the battery cycle of the test battery with the battery cycle models of different capacity degradation models associated with a value of the battery capacity closest to the current capacity of the test battery to select a battery cycle model closest to the battery cycle of the test battery and the degradation capacity model mapped to the selected battery cycle model. The system estimates future degradation of the capacity of the test battery based on the retrieved capacity degradation model.

  • Patent number: 10854868
    Abstract: Improvements in the structural components and physical characteristics of lithium battery articles are provided. Standard lithium ion batteries, for example, are prone to certain phenomena related to short circuiting and have experienced high temperature occurrences and ultimate firing as a result. Structural concerns with battery components have been found to contribute to such problems. Improvements provided herein include the utilization of thin metallized current collectors (aluminum and/or copper, as examples), high shrinkage rate materials, materials that become nonconductive upon exposure to high temperatures, and combinations thereof. Such improvements accord the ability to withstand certain imperfections (dendrites, unexpected electrical surges, etc.) within the target lithium battery through provision of ostensibly an internal fuse within the subject lithium batteries themselves that prevents undesirable high temperature results from short circuits.
