How to choose a cryopolymer battery or low temperature lithium polymer battery
A polymer battery that can operate at a temperature below -20 ° C is called a cryopolymer battery or low temperature lithium polymer battery. cryopolymer batteries are divided into conventional cryopolymer batteries (with a minimum operating temperature of -40 ° C) , ultra-low temperature polymer battery (minimum operating temperature is -55 ° C) .
In general, however, low-temperature lipo battery operate on low voltage platforms, such as a single lithium-ion battery at room temperature with a voltage range of 3-4.2 V, the platform range is around 3.6 V (that is, the longest working time in this voltage range) , but at low temperatures, even with low-temperature polymer batteries, the operating voltage range is between 3.5 and 2.5 V, if the operating current is high, the voltage in this operating range will be lower, so if you want to use a cryogenic polymer battery, it's not just about the operating temperature range, at the same time to consider the working voltage platform on your device can be used, it is best to test the actual. Or contact SER's technical staff to help you with a specific assessment, and then recommend a battery model you can use.
In general, the better the low-temperature performance of low-temperature polymer batteries, the worse their high-temperature performance, these two requirements are relatively contradictory, SER has now developed a wide-temperature type of low-temperature battery, it can work from 40 ° C below zero to 70 ° C above zero. It is important to use it in vehicle electronic equipment and other special products.
