The present disclosure provides a battery module. The battery module comprises: a plurality of mono-batteries arranged along an arrangement direction; and a frame receiving and fixing the plurality of mono-batteries. The battery module further comprises a plurality of isolating plates, each isolating plate is interposed between two adjacent mono-batteries, each isolating plate is provided with a through hole penetrating along the arrangement direction. Each isolating plate is configured to be capable of self-foaming to make a volume of each isolating plate expanded when each isolating plate is heated and a temperature of each isolating plate is more than 200 C. When one mono-battery suffers thermal runaway, the through hole of each isolating plate can form air thermal resistance, thereby preventing heat generated by the runaway mono-battery from massively and quickly transferring to the large surfaces of the adjacent mono-batteries, so as to achieve the purpose of thermal isolation.

An energy storage apparatus including: an outer case having an opening portion; a plurality of energy storage devices arranged in a first direction in the outer case; and a positioning projection disposed on opposedly facing inner side surfaces of the outer case, extending in a second direction substantially orthogonal to the first direction toward a lower side of the outer case opposite from the opening, and being capable of positioning the adjacently disposed energy storage devices at the lower side of the outer case.

A bipolar battery plate is utilized for production of a bipolar battery. The bipolar battery plate includes a frame, a substrate, first and second lead layers, and positive and negative active materials. The substrate includes insulative plastic with conductive particles homogeneously dispersed throughout the insulative plastic and exposed along surface of the substrate, the substrate positioned within the frame. The first lead layer is positioned on one side of the substrate, while the second lead layer is positioned on another side of the substrate. The first and second lead layer are electrically connected to each through the conductive particles. The positive active material is positioned on a surface of the first lead layer, and the negative active material positioned on a surface of the second lead layer.

An electrochemical assembly is comprised of dry electrochemical powder layers (e.g., anode layer, separator layer, cathode layer, and/or current collector layer) that are substantially free of solvent and/or binder. The electrochemical assembly is produced by directly disposing (e.g., printing/spraying) dry powder layers into a non-conductive frame.

A solid state battery cell has a frame formed by a non-electrically conductive material. The frame has a frame thickness (Tf). A cell core surrounded by and entirely within the frame has a cell-core thickness (Tc). The cell core includes at least one anode, at least one cathode and at least one electrolyte between the at least one anode and the at least one cathode. At least one cell-core swell-accommodating recess is surrounded by and entirely within the frame. The at least one cell-core swell-accommodating recess defines an internal cell volume into which the cell core is expandable and from which the cell core is contractible. The cell-core thickness (Tc) is less than or equal to the frame thickness (Tf) during cell-charge and/or cell-discharge cycling.

Disclosed are a battery module and a battery pack including the same. The battery module includes a frame; and a plurality of battery cells disposed at the frame, and the plurality of battery cells are arranged in a single layer with respect to the frame.

A battery pack, an integrated device for sensing individual battery voltage in a battery pack and a method of forming an integrated voltage-sensing circuit for use in a battery-powered automobile propulsion system. The integrated voltage-sensing circuit includes a busbar, a terminal pin and a voltage-sensing fuse electrically disposed between the busbar and the terminal pin. The construction of the voltage-sensing circuit is such that it forms an integral structure upon being coupled to the modular housing or related structure that may subsequently be secured to a frame that is used to provide support to each battery cell within the battery pack. In one form, the modular housing and voltage-sensing circuit may be secured to the frame during a frame molding process such that upon completion of the molding, the housing and at least a portion of the voltage-sensing circuit are encapsulated within the frame. In another form, the busbar or related voltage trace that signally couples each of the battery cells in a pack may be integrated into the frame, such as by overmolding.

Each of plurality of unit cells includes a current collecting plate including a first main surface and a second main surface that are arranged in a stacking direction of the plurality of unit cells. The unit battery includes a separator impregnated with an electrolytic solution, the unit battery being disposed on the first main surface, a seal member provided on the first main surface, the seal member surrounding a periphery of the unit battery, and the seal member being in tight contact with the current collecting plates adjacent to the seal member in the stacking direction by a pressing force from the fastening tool.
