Sodium Nickel-Manganese Oxide breaks the traditional sodium battery voltage range limit of 2-4V and can be charged up to 4.2V, greatly improving the energy density.
The principle of c is to use the energy generated by the high-frequency mechanical vibration of ultrasonic waves to weld non-ferrous metal materials of the same or different types.
The AOT-YCSM-20XZ automatic double-sided spot welder is suitable for spot welding of individual battery cells in series and parallel connection before assembly in PACK factories. The electrical control part of the spot welder adopts a modular design, featuring high integration, good versatility, and easy maintenance
