alkaline button cell
The alkaline button cell is a compact, high-performance power source that combines reliability with versatility in a small form factor. These cells utilize an alkaline electrolyte, typically potassium hydroxide, along with zinc and manganese dioxide as active materials to generate electrical power. The innovative design features a sealed, flat cylindrical shape that maximizes energy density while minimizing space requirements. These cells operate at a nominal voltage of 1.5V and are engineered to deliver stable power output throughout their service life. The manufacturing process incorporates advanced pressing and sealing techniques to ensure leak-resistant performance and extended shelf life, typically ranging from 2 to 5 years. Button cells are designed with specialized internal construction that prevents common issues like electrolyte leakage and ensures consistent power delivery even in varying environmental conditions. Their applications span across numerous devices, from watches and calculators to medical devices, key fobs, and small electronic toys. The cells' engineering prioritizes safety features, including child-resistant packaging and internal pressure release mechanisms.
