Which types of low-temperature-resistant batteries?

Which types of low-temperature batteries compare in performance with low-temperature batteries? I believe that those who don’t do batteries don’t know much, let alone what kind of low-temperature batteries are. Let's take a look at the types of low-temperature batteries and how they work. At present, common low-temperature batteries include low-temperature 18650 lithium batteries, low-temperature polymer lithium batteries, low-temperature lithium iron phosphate batteries, low-temperature nickel-hydrogen batteries and low-temperature batteries. Low temperature 18650 lithium battery 1. Low temperature 18650 lithium battery Since 18650, the size of lithium battery has been fixed, and its capacity has attracted the attention of many practitioners. In recent years, the technology has improved, and lithium battery manufacturers will also add new ones. Ability, especially like Samsung, Panasonic, LG, Sony, Toshiba can do more than 3600mah, but the stability and consistency of the low temperature performance of the lithium battery in 18650 is in the range of 2600mah~3000mah. It is worth noting that many buyers mistakenly believe that high capacity will lead to a large actual discharge current, and this is just the opposite: the low-temperature performance of 18650 lithium batteries is generally divided into capacity type and multi-type. The type of capacity mainly reflects the large capacity, but the discharge current is generally lower than 1C, and the current is small. The multiplier type can discharge large current, but the capacity is low and the use time is not long. How to distinguish the impact of the actual capacity of the 18650 lithium battery on the low-temperature performance? Unscrupulous manufacturers label ability but can't believe it, if you want to know the actual ability, you must pass the professional test charging and discharging test equipment test, so the average person does not know the specific The size is easy to be deceived by the seller. If the buyer really feels capable, he can ask the supplier for a problem test report or choose a third-party professional testing agency. The low-temperature performance-price ratio of 18650 lithium batteries is directly proportional to the capacity. The larger the capacity, the higher the energy ratio, and the more raw materials used, the more expensive the price. 2. The general range of low temperature lithium battery in the low temperature lithium polymer battery market is as follows: Charging temperature: 0℃~+45℃ Discharging temperature: -40℃~+60℃-40℃0.2c Discharge capacity ≥80%-30℃0.2 c Discharge capacity ≥90%-40℃ 0.5c Discharge capacity ≥70% Outstanding low-temperature cycle performance, can realize 0.2c charge-discharge cycle, 300-week capacity retention rate is over 85%, low-temperature high-power battery charging temperature: 0℃~ +45°C discharge temperature: -40°C~+60°C-40°C 3C discharge capacity ≥75%-40°C 1C discharge capacity ≥85% 3. Low temperature lithium iron phosphate battery At present, the low temperature performance of lithium iron phosphate battery is better than that of polymer Poor lithium battery. Specifically, we can know from its charge-discharge performance curve: low temperature is the charge-discharge curve of lithium iron phosphate batteries. 4. Due to the material characteristics of low-temperature nickel-hydrogen batteries, current low-temperature nickel-hydrogen batteries are generally mature at -20℃~50 ℃, can realize 1-5c multiple discharges, and can also charge at -30℃. 5. Low-temperature battery refers to the traditional lead-acid battery. Due to material characteristics and environmental pollution, the lead-acid battery on the market is slowly being replaced by lithium batteries or nickel-hydrogen batteries. Therefore, the lack of lead-acid batteries in the low-temperature field is mainly due to the future market demand, which determines the sustainable development potential of this field.
