  • Patent number: 11527364
    Abstract: A multilayer ceramic electronic component includes multilayer ceramic electronic component bodies which each include a multilayer body and first and second outer electrodes provided on both end surfaces of the multilayer body. The multilayer ceramic electronic component also includes a first metal terminal connected to the first outer electrodes and a second metal terminal connected to the second outer electrodes. Each multilayer ceramic electronic component body includes a dimension in a lamination direction that is less than a dimension in a width direction, and is positioned so that one of the first and second side surfaces faces a mounting surface. The first and second metal terminals extend between the first and second outer electrodes of the multilayer ceramic electronic component bodies. The multilayer bodies, first and second outer electrodes, and at least portions of the first and second metal terminals are covered by a cover material.

  • Patent number: 11417868
    Abstract: A manufacturing method for a secondary battery that includes coating a metal current collector sheet material with an electrode material layer raw material such that a shape of a coating surface of the electrode material layer raw material is changed based on a shape of a non-rectangular electrode to be formed to form an electrode precursor, and cutting the electrode precursor into a non-rectangular electrode shape.

  • Patent number: 11329323
    Abstract: A manufacturing method of a secondary battery is provided to improve a manufacturing efficiency of a non-rectangular electrode. The manufacturing method is provided for a secondary battery and includes forming the non-rectangular electrode. The step of forming the electrode includes, prior to forming an electrode precursor by applying an electrode material layer raw material to a metal sheet material that becomes a current collector, controlling a wettability of a local portion of a surface of the metal sheet material to the electrode material layer raw material and forming a wettability control region in the local portion. The local portion becomes a cutaway region of the non-rectangular electrode.

  • Patent number: 10629885
    Abstract: A case includes first and second opposed main surfaces and a side surface extending between the first and second main surfaces. An electrode body is housed in the case and including a first electrode, a second electrode, and a separator disposed between the first and second electrodes. First and second terminals are located on the side wall of the case. A first lead is electrically connected with the first electrode and extends from a side surface of the electrode body. A second lead is electrically connected with the second electrode and extends from the side surface of the electrode body. First and second connection members electrically connect the first and second leads to the first and second terminals, respectively. Each of the connection members includes a first part extending along the side surface of the case and a second part extending along the second main surface of the case.
