    Abstract: A cooling assembly according to various aspects of the present disclosure includes a housing, an electronic component, a dielectric coolant, and a cover. The housing includes an interior compartment having a basin region in which the electronic component and the coolant are disposed. The coolant undergoes phase change between a liquid state and a gas state. The coolant is in direct contact with the electronic component in the liquid state. The cover component extends transversely through the interior compartment and is coupled to the body. The cover component is disposed in a direction with respect to the basin region. The cover component at least partially defines a port in fluid communication with the basin region. The cover component is configured to permit flow therethrough of the dielectric coolant in the gas state in at least the direction.

    Abstract: Methods for press hardening galvanized, pre-treated, optionally non-annealed steel alloys are provided. The press-hardened steel alloy may have an ultimate tensile strength (UTS) of at least about 1,000 MPa and is substantially free of liquid metal embrittlement (LME). The press-hardened steel alloy may be further quenched to below room temperature. The press-hardened steel may have a multi-phase microstructure of ferrite at greater than or equal to about 1% to less than or equal to about 60% by volume and a combined volume percentage of martensite, retained austenite, and other transformation products at greater than or equal to about 40% to less than or equal to about 99%.

    Abstract: The present disclosure relates to electroactive materials for use in electrodes of lithium-ion electrochemical cells and methods of making the same, for example, methods for lithiating electroactive materials. A method of lithiating an electroactive material may include dispersing an electroactive material precursor within a room-temperature electrolyte that includes a lithium-based salt and contacting the electrolyte mixture and a lithium source so as to cause the lithium source to ionize and form lithium ions. The lithium ions may react with the electroactive material precursor to form a fully lithiated electroactive material (e.g., greater than 70% of total lithiation). The method further includes, in certain aspects, electrochemically discharging the fully lithiated electroactive material to form a lithiated electroactive material having an optimized lithiation state (e.g., less than or equal to about 40% of a first lithiation state of the fully lithiated electroactive material).
