AI Technical Summary
The existing electrolyte supply devices have inconsistent electrolyte amount and the introduction of debris during the electrolyte injection process, resulting in high failure rate and safety threats.
An electrolyte supply device for a secondary battery is designed, including an upper hopper unit, a lower hopper unit, a needle unit and a nozzle unit. By providing a first sealing member in the flow channel and determining the movement of the electrolyte by the weight of the needle unit, the holding of sealing force and minimizing debris is achieved. The nozzle unit is designed to disperse the direction of air introduction and reduce sputtering of the electrolyte.
The device can maintain sealing force during long-term use, reduce the generation of debris, ensure a constant supply of electrolyte, reduce failure rate and safety risks.
