Long life 3.0V lithium battery

Ensuring the optimal performance and longevity of Lithium Batteries is crucial, and their exposure to high and low temperatures significantly influences their lifespan. High temperatures pose the risk of explosion, while low temperatures can lead to lithium condensation, reducing electrolyte internal resistance and hindering quick charge and discharge processes.

To safeguard against potential hazards, lithium batteries in practical applications require specialized circuits for protection. These circuits play a vital role in preventing accidents resulting from voltage and current overload. Typically, a protection circuit encompasses a charging management IC, designed to interrupt the circuit in cases of overcharge and overdischarge. To enhance battery protection and extend its service life, the circuit is programmed to disconnect at around 3V, although this threshold may vary based on the strategies implemented by different brands and chips. Additionally, the protection circuit incorporates a fuse to manage current and prevent potential damage.

In summary, the implementation of protection circuits is essential for the safe and efficient use of lithium batteries, guarding against temperature-related issues, overcharging, and overdischarging. These measures contribute to the overall safety and longevity of Lithium Battery applications.
