Advanced Battery Injection Technology
Our injection system introduces a groundbreaking approach to battery filling, emphasizing precision, cleanliness, and efficiency to elevate manufacturing standards:
Injection Method:
Employing a no-pressure-differential technique, the system injects electrolyte into batteries without creating internal or external pressure discrepancies. This method safeguards against battery casing deformation during the injection process, particularly under positive and negative pressure conditions.Optimized Soaking Time:
By streamlining the injection procedure, our system significantly reduces the soaking time required for batteries, thereby enhancing overall equipment efficiency and throughput.Injection Pressure Control:
During electrolyte injection, a precisely regulated positive pressure of 0.6 MPa nitrogen is maintained both inside and outside the battery. This balanced pressure application ensures uniform filling and minimizes potential stress on the battery structure.Enhanced Cleaning Measures:
Prior to injection, an integrated injection cup and nozzle cleaning system is activated. This proactive measure improves injection accuracy while preventing any cross-contamination from the nozzle to the battery, ensuring product purity.Residual Liquid Management:
Post-injection, a residual liquid connection system is implemented to collect excess electrolyte, effectively preventing shell contamination and maintaining a clean production environment.Innovative Injection Nozzle Design:
Tapered injection nozzles are utilized to navigate the contours of the battery injection port seamlessly, avoiding angular connections that could trap electrolyte and hinder effective cleaning. This design promotes complete cleaning and minimizes process inefficiencies.Flexible Production Capacity:
The equipment’s production capacity is dynamically scalable, unbound by fixed process times. As production demands grow or change, additional injection units can be incorporated into the system to effortlessly match production targets, ensuring that your manufacturing capabilities remain agile and adaptable.
