Abstract: A thermal barrier component for an electrochemical cell (e.g., a battery) includes a mat, a functional material, and a polymer binder. The mat includes a porous matrix. The functional material is in pores of the porous matrix. The functional material includes an oxide. In certain aspects, the functional material may be a composite material. The polymer binder is in contact with the porous matrix and the functional material. At least one of the porous matrix, the functional material, and the polymer binder is configured to serve as an intumescent carbon source. The oxide is configured to catalyze thermal degradation of the intumescent carbon source to form intumescent carbon at a first temperature. The first temperature is greater than or equal to about 300° C. The thermal barrier component is configured to mitigate thermal runaway in an electrochemical cell. The thermal barrier component may include one or more layers.

Abstract: Aspects of the disclosure include air flow systems configured to regulate air flow when laser welding to improve laser weld quality. An exemplary air flow system can include a primary inlet coupled to an air source and one or more secondary inlets coupled to the primary inlet. At least one of the one or more secondary inlets can include an internal valve. Each internal valve is actuatable between a fully open state, a fully closed state, and an intermediate state. The air flow system can further include an outlet coupled to each of the one or more secondary inlets downstream of the internal valve and a controller configured to adjust a position of each internal valve. The controller is configured to adjust the position of each internal valve based on an air flow mapping to increase an average air flow velocity along a laser beam of a welding laser.
