Li-MnO₂ Primary Battery | 3V Coin & Cylindrical Cell Factory
Introduction
As a leading manufacturer specializing in lithium primary battery technology, we understand the critical role that Li-MnO₂ (Lithium-Manganese Dioxide) batteries play in powering modern electronic devices. This comprehensive guide explores our 3V coin and cylindrical cell production capabilities, technical specifications, and application solutions designed for B2B partners seeking reliable power sources for their products.
Core Technology Overview
Li-MnO₂ primary batteries represent the industry standard for 3V non-rechargeable power solutions. Our manufacturing process utilizes high-purity metallic lithium as the anode and specially treated manganese dioxide as the cathode material. The electrolyte system consists of lithium perchlorate (LiClO₄) dissolved in a mixed organic solvent of propylene carbonate (PC) and 1,2-dimethoxyethane (DME), ensuring optimal conductivity and stability across diverse operating conditions.
Key Technical Advantages
High Energy Density: Our cells deliver energy density up to 330Wh/kg, providing extended operational life for demanding applications while maintaining compact form factors.
Wide Temperature Range: Standard operating temperatures span from -20°C to +60°C, with customized solutions available for extreme environment requirements.
Low Self-Discharge Rate: Advanced sealing technology ensures less than 1% annual self-discharge, enabling 10-year shelf life under proper storage conditions.
Stable Voltage Output: Consistent 3.0V nominal voltage throughout discharge cycles ensures reliable performance for sensitive electronic circuits.
