  • Publication number: 20220251708
    Abstract: Apparatus, methods, and systems use hydrogen radicals during a thermal annealing of film stacks to reduce or remove contaminants (such as phosphorus) from the film stacks. In one implementation, a method of processing a film stack of a substrate, includes conducting a thermal anneal operation on the film stack while the substrate is directly supported on a pedestal heater. The thermal anneal operation includes reducing one or more of a stress or a bow of the film stack. The method includes conducting a radical treatment operation on the film stack after the thermal anneal operation is conducted. The radical treatment operation includes exposing the film stack to hydrogen radicals, and removing contaminant particles from the film stack.

  • Publication number: 20220236333
    Abstract: Embodiments of this application provide a method and a device for detecting abnormality of a lithium battery, a battery management system, and a battery system. The method includes: obtaining a SOC value of the lithium battery in a charge process, where the SOC value is a ratio of a remaining capacity of the battery to a nominal capacity of the battery; changing a value of a charge current at a time point corresponding to an arbitrary SOC value, and obtaining a response signal within a time period of maintaining the changed charge current; and determining, based on response signals at time points corresponding to a plurality of SOC values, whether the lithium battery is abnormal. The method can implement non-destructive detection of abnormality of a lithium-ion battery, simplify operation, and achieve relatively high accuracy.
