How can polymer batteries adapt to different temperature environments?18650 battery 3.7v 6000mah

　　Assuming that the working voltage of the polymer battery remains stable and the charge discharge flow rate decreases. The output power output of polymer batteries will also decrease. If the temperature rises, the opposite will happen. The power of polymer batteries will increase. Temperature also affects the transmission speed of lithium battery electrolyte, with an increase in temperature accelerating and a decrease in temperature slowing down: the charging characteristics of polymer batteries can also be affected. But the temperature is too high. It can disrupt the chemical reaction balance inside the polymer battery.

　　After the battery is assembled and injected with liquid, it will undergo a battery charging stimulation, commonly known as formation, and the required 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 required temperature for capacity testing is 35 ± 5 ℃.

　　The storage temperature of batteries is generally 25 ± 5 ℃ at room temperature, which can affect the activity of lithium iron phosphate. The higher the temperature, the higher the enzyme activity. However, if the temperature exceeds 60 ℃, it is likely to inevitably damage the protective film inside the polymer battery, leading to battery damage. If the temperature is too low, the vitality of lithium iron phosphate will be too low, causing the battery capacity to not be discharged, which means it is out of charge.

　　In the winter of northern regions, this is why a fully charged mobile phone in a room cannot make calls outdoors. But this only needs to be repaired after returning to the normal temperature state, and the impact on the battery is not very significant. When applied at 35 ℃, batteries have relatively high capacity, and as the temperature increases, the impact on capacity is relatively small. However, if the temperature exceeds 60 ℃, it is likely to harm the battery and thus affect its service life.
