Assuming that the voltage of the polymer battery remains constant and the discharge current decreases. The power output of polymer batteries will also decrease. If the temperature rises, the opposite is true. The output power of polymer batteries will increase. Temperature also affects the transmission speed of electrolyte, with an increase in temperature accelerating and a decrease in temperature slowing down: the charging and discharging performance of polymer batteries will also be affected. But the temperature is too high. It will disrupt the chemical balance inside the polymer battery.
After the battery is assembled and injected with liquid, it will be charged and activated once, which is called formation. The specified temperature for formation is 45 ± 5 ℃.
After being formed and allowed to stand for a period of time, a capacity test will be conducted to charge the battery. The specified temperature for capacity testing is 35 ± 5 ℃.
The storage temperature of batteries is generally 25 ± 5 ℃, which affects the activity of lithium ions. The higher the temperature, the higher the activity. However, if the temperature exceeds 60 ℃, it may cause irreversible damage to the isolation film inside the polymer battery, leading to battery scrapping. If the temperature is too low, the lithium ion activity will be too low, resulting in the battery capacity not being discharged, which means it is out of charge.
In winter in the north, this is the reason why a fully charged indoor phone cannot make calls outdoors. But as long as it returns to room temperature, it will recover, and the impact on the battery is not very significant. When a battery is used at 35 ℃, its capacity is relatively high. If the temperature rises again, the impact on capacity is relatively small. However, if the temperature exceeds 60 ℃, it may damage the battery and thus affect its lifespan.
If the temperature is too low, it will result in a lower capacity, which means that some of the electricity is not discharged. Overall, the capacity difference of batteries during normal use is not significant. Taking lithium iron phosphate cells as an example, the capacity at 20 ℃ is only about 0.95% lower than that at 45 ℃, which is less than 1%.
