摘要： A composite electrode foil roll for manufacturing an electrolytic capacitor, including: bands of electrode foils; strips of an isolating material positioned along a width of the composite electrode foil roll at a plurality of locations. The plurality of locations are at equal distances and correspond to a length of an inner cavity of a case of the electrolytic capacitor. The bands of electrode foils and strips of an isolating material are alternating. A method of manufacturing the composite electrode foil roll including alternating bands of electrode foils and strips of an isolating material. The strips are positioned along a width of the composite electrode foil roll at repeated locations. The repeated locations are at equal distances corresponding to a length of an inner cavity of a case of the electrolytic capacitor.

摘要： Electrolytic capacitors may use a canister and a lid to confine an electrolyte and prevent the electrolyte from evaporating during use, and an improved seal between the canister and the lid may be achieved by increasing the surface area of the seal. For example, the surface area of the seal may be increased by changing the shape and/or thickness of the canister edge. For example, the surface area of the seal may be increased by changing the shape of an elastomer layer of the lid and/or adding an annular protuberance at the circumference of the lid. For example, the surface area of the seal may be changed by changing the process for forming the edge during the capacitor sealing.

摘要： A capacitor manufacturing method described herein includes a process for the isolation of edges of electrode foils in an electrolytic capacitor after slitting the electrode foils from a mother foil. For example, a coating process may be incorporated into the capacitor manufacturing so that the edges of the electrode foils may undergo isolation with a deposition of a layer of epoxy or resin. A manufacturing machine that incorporates a resin coating process may be positioned in the manufacturing line, such that the edges of the slit electrode foils undergo a deposition of a coating of an electrical isolator, such as a polymer, an epoxy, a resin, a ceramic, and/or an oxide layer. As another example, a combined foil with interleaving conducting bands and isolating strips may also be used to form the electrode foils with isolated edges.

摘要： A capacitor manufacturing method is disclosed herein that includes a process for the isolation of electrode tabs attached to the capacitors' electrodes from other elements in the capacitor. An isolation patch or layer may be deposited over the tabs by a machine or a device after the tab is attached and before the electrodes are wound into a cylindrical internal element of a capacitor. The device may coat the tabs and surrounding regions with an isolating material. Electrode tabs may be provided with an isolating material pre-deposited at least in part over the tabs.

摘要： Devices, systems, and methods for mitigating thermal runaway in electrical energy storage batteries. A pouch includes a seal and a sealed opening. Within the pouch are a porous support material (such as concrete, glass, cellulous, etc.) and a heat absorbing material (such as water, hydrogel, an organic liquid, etc.) For example, water may be a heat absorbing material and a glass framework may be used as a support material. For example, a pouch may be placed on either side of a lithium battery in a battery pack, and when the lithium battery enters thermal runaway, the heat absorbing material my change phase from a liquid to a vapor, and the vapor pressure causes the sealed opening to open, and the vapor to escape the pouch. This allows the heat to be released from the battery pack and protects the neighboring batteries from an increase in temperature.
