Is the internal resistance of polymer lithium batteries better or smaller? internal resistance is sensitive to temperature, and the internal resistance value can be greatly changed at different temperatures. One of the main reasons for the reduction of the characteristics of lithium ion at low temperatures is that the battery has a large internal resistance at ultra-low temperatures. The smaller the internal resistance, the better, and a small internal resistance is a necessary standard.
Lithium polymer battery high internal resistance cannot be discharged at a large current. The lower the theoretical internal resistance, the better. The internal resistance and capacity are directly related. For general lithium polymer batteries, assuming that the internal resistance of 1 ampere is about 30 to 80 hauo, while a good power lithium battery can reach below 15 hauo. When the internal resistance increases, the heat loss of the itself increases. When the temperature increases during use, the battery performance will be worsened. After being used in series with other batteries, there is a problem of mismatch, resulting in a decline in the overall battery pack capacity and performance.
1. The internal resistance is large. When discharged, the lithium battery will heat up higher.
2. Small internal resistance and less power consumption.
With the maturity of lithium battery research and development technology and the increase in mobile work requirements of portable medical instruments, lithium batteries have gradually occupied a leading position in the medical instrument industry with their absolute advantages of high voltage, high energy and long life.
