摘要： A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having a via hole providing an electrically conductive pathway extending through the container. A metal lid closes the open-end of the container. An electrode assembly housed inside the casing comprises an anode current collector deposited on an inner surface of the ceramic container in contact with the electrically conductive pathway in the via hole. An anode active material contacts the current collector and a cathode active material contacts the metal lid. A separator is disposed between the anode and cathode active materials. That way, the electrically conductive pathway serves as a negative terminal, and the lid, electrically isolated from the conductive pathway by the ceramic container, serves as a positive terminal. The negative and positive terminals are configured for electrical connection to a load.

摘要： Embodiments of the invention provide a battery pack including a pack body and a plurality of terminals. The pack body has first and second main surfaces that are opposed to each other in a first axis direction, first and second end surfaces that are opposed to each other in a second axis direction orthogonal to the first axis direction, and first and second side surfaces that are opposed to each other in a third axis direction orthogonal to the first axis direction and the second axis direction. The plurality of terminals includes a positive terminal, a negative terminal, a temperature detection terminal, and a control terminal that are arranged on the first end surface along the third axis direction. The negative terminal is arranged between the temperature detection terminal and the control terminal and closer to the control terminal than the temperature detection terminal.

摘要： A prismatic lithium ion battery cell includes a packaging having a cover. The cover includes: a first spiral disk feature disposed below a first terminal pad; a second spiral disk feature disposed below a second terminal pad; a first reversal disk disposed below the first spiral disk feature; and a second reversal disk disposed below the second spiral disk feature. The first and second reversal disks are configured to deflect upwards to displace the first and second spiral disk features to contact the first and second terminal pads, respectively, in response to a pressure within the packaging being greater than a predefined pressure threshold and form an external short-circuit between the first and second terminal pads via the first and second spiral disk features. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow between the first and second terminal pads.
