    Abstract: Aspects of the subject disclosure relate to battery cells having an electrode roll, and one or more current collectors at one or more ends of the electrode roll. Tabs extending from electrodes of the electrode roll at an end of the electrode roll may be folded into contact with the current collector at that end of the electrode roll, without overlapping the tabs.

  • Publication number: 20250219598
    Abstract: Disclosed is a method and standard module for amplifying pulsed power. The key point of the technical solution is as follows: a method for amplifying pulsed power is formed by means of the joint action of a LASER mode of a crystal medium, a carrier multiplication amplification mode of a semiconductor medium, and a plasma breakdown amplification mode of a gas medium. Electric power which is amplified is converted into optical power first, the optical power is amplified again, and the amplified optical power is converted into electric power again by a photoelectric conversion and amplification device. A gas switch is triggered based on a photoconductive switch to generate a timing-synchronized high-power electric pulse. The high-power electric pulse may be directly outputted or distributed in multiple channels to obtain multiple timing-synchronized trigger signals. In combination with pulse charge of a capacitor, multiple timing-synchronized high-power electric pulses are outputted.
