Why does winter affect the use of lithium batteries?

Fortunately, most of the electric mobility devices received by electric mobility are 18650 lithium batteries. 18 implies a tortuous diameter of 18mm, 65 implies a length of 65mm, and 0 implies a cylindrical battery lithium battery temperature. Lithium battery temperature: speed science popularization|Why does the lithium battery not last well in winter?

All the lithium ions inside the lithium battery are retained in the positive electrode, while the negative electrode is made of graphite (carbon) to form the lithium battery temperature. The electrolyte and diaphragm are contained between the positive and negative poles. The discharge process of the lithium battery is the movement process of lithium ions from the negative electrode to the positive electrode, and the discharge of the lithium battery is used to supply the electric energy required for the operation of the electric vehicle.

Lithium battery temperature: speed science popularization|Why does the lithium battery not last well in winter? When the temperature drops, the charging and discharging process will slow down the temperature of the lithium battery. Therefore, the discharge current becomes smaller, and the battery capacity becomes smaller. The marked working temperature of lithium battery is 0-40℃.

But in fact, when the temperature is lower than 25℃, there will be a certain level of performance degradation: the battery capacity decreases, the discharge speed becomes slower, and the battery output power decreases. Lithium batteries can reach a greater capacity value at 25°C, which is the test temperature of lithium batteries in various endurance tests. In fact, due to the different materials and processes of lithium batteries, the data is slightly different.

Finally, if you live in cold winter, you can choose our batteries with pre-heating. Lithtech batteries can provide pre-heating fuction with you so that it can make sure that the battery is charged and discharged normally in a cold environment. Just contact us(info@lith-tec.com)!
