Telecom Li-ion Batteries

1. The rate characteristics of battery capacity

As the discharge current increases, the discharge capacity of the battery will decrease. When the discharge rate is less than 0.33C10, the discharge capacity of the lithium-ion battery is minimally affected by the discharge rate, and the difference in discharge capacity is not significant. It can be basically concluded that the capacity of the battery can be fully discharged. Figure 2 shows the relationship curve between rate and constant current discharge voltage and capacity at 20 degree .

2. Temperature characteristics of battery capacity

When the ambient temperature is above {{0}} degree , the decay rate of battery capacity is slower, while when the ambient temperature is below 0 degree , the decay rate of battery capacity is faster. As the temperature decreases, the internal resistance of the battery increases sharply.
