A battery module, and a battery pack and a vehicle, each including the battery module. The battery module includes a frame; a plurality of battery cells arranged in the frame; a heat sink in contact with one side of the battery cell; and a cooling fin in contact with the heat sink and in contact with the other side of the battery cell.

A battery lid is formed of a metal plate integrally formed with a valve and a surrounding plate portion surrounding the valve which facilitates rupturing the valve at a predetermined pressure. The valve includes a pressure receiving plate portion having a bending groove, and bendable from the bending groove by applied pressure, and a thin plate portion thinner than the thickness of the surrounding plate portion, and connects the pressure receiving plate portion to the surrounding plate portion. The thin plate portion has a rupture groove passing through extension sections on the respective lines extending from the bending groove. As the pressure receiving plate portion is deformed by the pressure applied to the valve, the extension sections are pulled more strongly than are the other sections in the valve. Therefore, when a predetermined pressure is applied, the valve is ruptured from the extension sections of the rupture groove.

A holding apparatus (15) for current and signal conductors of a traction battery of a motor vehicle has a plate-like base body with longitudinal sides (16), transverse ends (17) and a top (18) and bottom (19) extending between the longitudinal sides (16) and transverse ends (17). Elements (20) are arranged on the top (18) and the bottom (19) for guiding and fixing current conductors (12) of the traction battery, and elements (21) are arranged on the other of the top (18) and the bottom (19) for guiding and fixing at least one signal conductor (14) of the traction battery. The base body provides EMC shielding of the signal conductor (14) from the current conductors (12). The plate-like base body has on the opposite longitudinal sides (16) and/or on the opposite transverse sides (17) sections (22) for securing and grounding the holding apparatus on a frame of the motor vehicle.

A power storage module includes an array including power storage devices each having first and second surfaces opposite to each other in a first direction, a first restraint member facing the first surface of each power storage device, and a second restraint member facing the second surface of each power storage device. Dimensions of the power storage devices in a second direction perpendicular to the first direction are larger than respective dimensions of the power storage devices. The power storage devices are arranged in a third direction perpendicular to the first and second directions. The first restraint member extends in the third direction and restrains the array in the third direction. The second restraint member extends in the third direction and restrains the array in the third direction. At least one of the first and second restraint members has a hole therein. The hole is a recess falling in the first direction or a through-hole passing through the restraint member in the first direction.

A wiring module includes a first flexible printed circuit and a second flexible printed circuit that is separate from the first flexible printed circuit. The first flexible printed circuit and the second flexible printed circuit are arranged so as to be continuous in a first direction and are shaped as a band that extends in the first direction. A connector is mounted to each of the first flexible printed circuit and the second flexible printed circuit. The fitting direction in which the connector mounted to the first flexible printed circuit is fitted to a partner connector is different from the fitting direction in which the connector mounted to the second flexible printed circuit is fitted to a partner connector.

A secondary battery that includes an electrode assembly; an exterior body defining a housing space that houses the electrode assembly; a positive electrode terminal that includes a first metal layer made of nickel and a second metal layer made of a metal other than nickel, the first metal layer of the positive electrode terminal is exposed from the exterior body, and the first metal layer has a fixing face; and an insulating material positioned so as to fix the fixing face of the first metal layer to an inner wall of the exterior body, and the insulating material abuts against a face of the positive electrode terminal other than the fixing face of the first metal layer.

An apparatus for measuring a pressure of battery cells includes a pressure sensor configured to measure the pressure of battery cells stacked in the interior of a battery module, the pressure sensor includes a plurality of pressure measuring units, a connection unit for connecting the plurality of pressure measuring units to each other, and an output unit connected to the connection unit and configured to output pressure values measured through the pressure measuring units, and the plurality of pressure measuring units are arranged on surfaces of the battery cells to measure the pressure of the battery cells.

The fabrication of single-crystalline ionically conductive materials and related articles and systems are generally described.

It is described a Zn—Fe quasi-solid redox battery (QSRB) making use of low cost and earth abundant materials as reactive species, comprising: —a first half-cell comprising a first quasi-solid electrolyte in which are dissolved Zn.sup.2+ ions or a first quasi-solid electrolyte in which are dispersed organic and/or inorganic electroactive particles containing zinc ions in different oxidation states, and a current collector and an electrode disposed within the first half-cell; —a second half-cell comprising a second quasi-solid electrolyte in which are dissolved Fe.sup.2+ and Fe.sup.3+ ions or a second quasi-solid electrolyte in which are dispersed organic and/or inorganic electroactive particles containing Fe.sup.2+ and Fe.sup.3+ ions, and a current collector and an electrode disposed within the second half-cell; and —a separator between the two half-cells.

A structural component for a vehicle may include an extrusion that is extruded into a first state and then expanded into a second state. The extrusion in the first state has a reduced size relative to a desired final size. The extrusion in the first state is placed within a die that defines the desired final size. Pressurized water is distributed within internal cells of the extrusion in the first state such that the walls defining the internal cells are expanded into engagement with the surface of the die, thereby creating surface features or sealing interfaces with tight tolerances. The relative shape of the die and the extrusion in the first state defines an open space herebetween, into which the extrusion may expand to define the final shape. Some of the internal cells may be plugged such that they are not provided with pressurized water.
