摘要： A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.

摘要： Provided is a method for producing a welded article. The method welds a plurality of members by laser welding or electron beam welding to form a welded portion and produce a welded article having an internal space. The method includes forming the welded portion surrounding the internal space, and at least one of forming an end point portion of the welded portion outside of the welded portion surrounding the internal space, forming the welded portion by moving a laser or an electron beam from the inside to the outside of the outer edge of the plurality of members, forming another welded portion overlapping with the end point portion of the welded portion previously formed, or forming the end point portion of the welded portion in a region surrounded by the welded portion partitioning the internal space.

摘要： A current interrupt mechanism includes a partition wall defining a second space that is independent from a first space, and the partition wall includes a current path portion serving as a current path of a sealed battery. The current interrupt mechanism interrupts the current path in response to an internal pressure of the second space that is higher than a predetermined pressure. One conductive path passes through the current path of the current interrupt mechanism, and is in contact with the second electrolyte solution enclosed in the second space. Another conductive path includes a potential application line that is wired to the second electrolyte solution enclosed in the second space.

摘要： A positive electrode material of the present disclosure includes a positive electrode active material, a first solid electrolyte including a sulfide solid electrolyte, and a second solid electrolyte including a halide solid electrolyte. A proportion x of a volume of the second solid electrolyte to a sum of a volume of the first solid electrolyte and the volume of the second solid electrolyte satisfies 20≤x≤95 in percentage. The proportion x satisfies, for example, 35.2≤x≤76.5 in percentage.
