A battery module is provided. According to an embodiment of the present disclosure, the battery module may include: a cartridge assembly including a plurality of cartridges, each receiving a battery cell; a casing surrounding the cartridge assembly; and a support member configured to enclose the casing for supporting the casing.

A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive and non-automotive applications. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween. A plurality of rods extend through the each heatsink assemblies to secure the heatsink assemblies and the cell with one another to form the battery module.

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.

A method produces a laminate-type battery which can suppress short-circuiting even when a positioning guide is used. The method for producing a laminate-type battery having a first current collector layer, a first active material layer, a solid electrolyte layer or a separator layer, a second active material layer, and a second current collector layer laminated in this order, the method includes arranging a first layer along a first contact surface of a positioning guide, rotating the positioning guide, and thereafter arranging a second layer on the arranged first layer along a second contact surface of the positioning guide. The first layer and the second layer are different from each other and include an arbitrary layer selected from the first current collector layer, the first active material layer, the solid electrolyte layer or the separator layer, the second active material layer, and the second current collector layer.

A battery module includes: a battery stack including cells that are tabular and laminated on one another; and a first module reinforcement plate that is metallic and disposed in at least a position, included in positions that cover a plurality of outer surfaces excluding a pair of first outer surfaces at both outer sides along a lamination direction of the battery stack, that substantially covers an entirety of a second outer surface having a maximum area.

Elements of an electrochemical cell using an end to end process. The method includes depositing a planarization layer, which manufactures embedded conductors of said cell, allowing a deposited termination of optimized electrical performance and energy density. The present invention covers the technique of embedding the conductors and active layers in a planarized matrix of PML or other material, cutting them into discrete batteries, etching the planarization material to expose the current collectors and terminating them in a post vacuum deposition step.
