Lithium ion battery operating temperature

Generally, polymer batteries with a working temperature lower than -20 ° C are called low temperature polymer batteries , and low temperature polymer batteries are classified into ordinary low temperature polymer batteries (minimum operating temperature is -40 ° C), ultra low temperature polymer batteries (minimum operating temperature is -55 ° C).

However, low-temperature polymer batteries generally operate at lower voltage platforms. For example, a single lithium-ion battery at room temperature has an operating voltage range of 3-4.2V and a working platform range of about 3.6V (that is, at this voltage). The section works for the longest time), but at low temperatures, even with low-temperature polymer batteries, the working voltage range is mainly between 3.5-2.5V. If the operating current is relatively large, the voltage in this working range will be lower. So if you need to use a low-temperature polymer battery, you should not only look at the operating temperature range, but also consider whether the working voltage platform can be used on your equipment. It is best to test it. Or contact the technical staff of Dongguan Yunfan Electronic Technology Co., Ltd. to help you evaluate it, and then recommend the battery model that can be used.

Generally speaking, the lower the low temperature capability of the low temperature polymer battery, the worse is the high temperature performance. These two requirements are contradictory. At present, Yunfan Electronic Technology Co., Ltd. has developed a wide temperature type low temperature battery. It works at minus 40 ° C to 70 ° C, mainly for products with special requirements such as in-vehicle electronic equipment.
