Technical Strength

A strong R&D team and advanced technical strength provide a solid guarantee for product innovation.

R&D Center

R&D Innovation

We continuously tackle core technologies such as leak-proofing, long-lasting endurance, and low-temperature discharge. Through industry-university-research collaboration, we iteratively improve formula structures and can customize carbon zinc and alkaline battery solutions for digital, remote control, and outdoor equipment, continuously solving industry pain points like capacity fade and leakage.

Intelligent Manufacturing

Intelligent Manufacturing

Fully automated integrated intelligent production line, with mechanical automation for all processes including batching, coating, sealing, and sorting. This greatly reduces human error, enables large-scale standardized production, balances large order delivery efficiency with product parameter consistency, and reduces production waste.

Quality Control

Quality Control

Incoming raw material inspection, real-time process patrol inspection, and 100% visual inspection of finished products. Each batch of batteries undergoes reliability tests such as constant current discharge, long-term storage aging, and leak-proof sealing. All quality inspection records are kept and traceable. We adopt internal control standards higher than national standards to eliminate common quality defects like battery leakage.

Core Technology Advantages

  • Self-developed formulation materials: positive manganese powder, negative zinc paste, and electrolyte are independently proportioned, Increase capacity, reduce liquid leakage, and extend storage shelf life.
  • Sealing and leak-proof technology: Integrated sealing and multiple leak-proof structures to enhance safety and stability.
  • Low self-discharge technology: Suppresses internal side reactions, low loss during room temperature storage, and ultra-long storage life.
  • Environmentally compliant formula: Mercury-free and cadmium-free, meeting IEC, EU RoHS and other domestic and international export certification standards.
  • Cost and energy control technology: High raw material utilization rate and optimized energy consumption, providing a price competitive advantage at the same capacity.
  • Multi-category adaptation development: Rapid iteration of carbon zinc, alkaline, and high-power specialty batteries to suit multiple scenarios.
