A multilayer ceramic capacitor includes a multilayer body including dielectric layers. A difference between an RGB value which reproduces a color tone of ends in a width direction y of a first and second main-surface-side outer layer portions of the multilayer body and an RGB value which reproduces a color tone of ends in the width direction of a first and second side-surface-side outer layer portions is not smaller than about 45 and not larger than about 100, a monotectoid phase is provided in the first and second side-surface-side outer layer portions in a WT cross-section, includes at least one of Ca and Si, and a region where the monotectoid phase is provided is not larger than about 3% of a total area of the first and second side-surface-side outer layer portions in the WT cross-section of the multilayer body.

Multilayer ceramic capacitor including monotectoid phase

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.

Multilayer ceramic electronic component including a plurality of bodies and metal terminals connected to outer electrodes

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.

Manufacturing method for secondary battery

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.

Manufacturing method of secondary battery

A method for manufacturing a secondary battery by performing two or more kinds of intermittent coating in combination using two or more die heads so as to apply an electrode material layer-forming raw material to a metal sheet material to obtain an electrode precursor; and cutting the electrode precursor to form a plurality of electrodes.

Method and apparatus for manufacturing secondary battery

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.
