A battery manufacturing method includes assembling a plurality of flat batteries; and binding a battery stack including the plurality of assembled batteries arranged in one direction by a binding member and blowing cooling fluid on the battery stack through a fluid supplying part to cool the battery stack. The method includes causing cooling fluid discharged from a fluid supplying part through a first discharging part and cooling fluid discharged from the fluid supplying part through a second discharging part to collide and merge together, and then flow outward in the second direction through the apertures.

A battery pack protects the internal battery pack components from the heat, e.g., heat generated during a sterilization process of an autoclave. The battery pack prevents the heat of the autoclave from damaging the battery cells and other electronic components within a battery pack housing. The battery pack may include a multi-layer thermal protection portion lining an inside surface of the walls of the battery pack housing with a combination of materials designed to limit the amount of heat to which the internal components of the battery will be exposed for the duration of a traditional autoclave sterilization cycle. Additionally, the battery pack may include a thermal protection casing around connection elements, such as wires and contacts, between a battery pack contact and the battery cells, to limit the heat rise from the heat of the autoclave in or on the connection elements of the battery pack.

A marine battery pack including an enclosure defining a cavity, a plurality of cell modules within the cavity, each comprising a plurality of battery cells, and at least one sensor configured to sense at least one of a temperature, a pressure, a presence of water, and a gas content within the cavity. A controller is configured to detect an event warranting decommission of the battery pack based on the temperature, the pressure, the presence of water, and/or the gas content within the cavity, and then to automatically operate a pump to intake water from outside of the enclosure and pump water through the cavity from an inlet port in the enclosure to an outlet port in the enclosure so as to cool the plurality of battery cells.

The present disclosure relates to a positive electrode for a solid electrolyte battery which includes: a positive electrode current collector; a first positive electrode active material layer formed on at least one surface of the positive electrode current collector and including a first positive electrode active material, a first solid electrolyte and a first electrolyte salt; and a second positive electrode active material layer formed on the first positive electrode active material layer and including a second positive electrode active material, a second solid electrolyte, a second electrolyte salt and a plasticizer, wherein the plasticizer has a melting point of 30-130° C. The present disclosure also relates to a solid electrolyte battery including the positive electrode.

The disclosed technology includes devices, systems, and methods for a battery-integrated heat pump system. The disclosed technology can include a heat pump system having a battery, a compressor, and a variable speed drive in electrical communication with the battery and the compressor.

A battery manufacturing apparatus includes a binding member for bounding a battery stack and a fluid supplying part for blowing cooling fluid onto the bound battery stack. The binding member includes a first both-side part for bounding batteries from both sides by applying a load thereon in a first direction in which the batteries are arranged, and a second both-side part to be placed on both sides of the batteries to face both side surfaces of the batteries in a second direction different from the first direction. The binding member is formed with apertures through which the cooling fluid flows outward in the second direction. The fluid supplying part includes a first discharging part and a second discharging part for discharging the cooling fluid from both sides in a third direction different from both the first direction and the second direction toward the battery stack bound by the binding member.
