China Li-MnO₂ Coin Cell Factory | Full Series Supply
Professional Primary Lithium Battery Manufacturing Solutions for Global B2B Partners
As the global demand for reliable primary lithium batteries continues to surge, China has emerged as the leading manufacturing hub for Li-MnO₂ coin cell batteries. For B2B buyers seeking dependable power solutions, partnering with a established Chinese factory offers significant advantages in quality, capacity, and cost efficiency. This article provides a comprehensive overview of what professional buyers should expect from a full-series Li-MnO₂ coin cell supplier.
Understanding Li-MnO₂ Coin Cell Technology
Lithium Manganese Dioxide (Li-MnO₂) coin cells represent one of the most mature and widely adopted primary lithium battery technologies. Operating at a nominal voltage of 3.0V, these batteries deliver exceptional energy density, stable discharge characteristics, and extended shelf life exceeding 10 years. The electrochemical reaction between lithium metal anode and manganese dioxide cathode ensures consistent performance across diverse temperature ranges from -20°C to +70°C.
Key technical specifications that B2B buyers should evaluate include:
- Capacity Range: From 30mAh (CR1025) to 620mAh (CR2477) across standard coin cell sizes
- Self-Discharge Rate: Less than 1% per year under proper storage conditions
- Operating Temperature: -20°C to +70°C for standard grades; extended ranges available for specialized applications
- Compliance Standards: IEC 60086-4, UL 1642, UN 38.3, RoHS, and REACH certifications
