Low-temperature lithium-ion battery refers to a lithium-ion battery that can work normally in a very low temperature environment. Low-temperature lithium-ion batteries include low-temperature 18650 lithium-ion batteries, low-temperature soft-pack polymer lithium-ion batteries, and low-temperature lithium iron phosphate lithium-ion batteries. Low-temperature lithium-ion batteries are widely used because they have the advantages of light weight, high specific energy and long life. Low-temperature lithium-ion batteries are made of special materials and processes and are suitable for use in sub-zero cold environments.
Electronic devices have become an indispensable part of people's lives, but these rely on battery-powered electronic products may have some headaches. Many explosions of lithium-ion batteries have made people realize that small lithium-ion batteries may also cause significant harm. The explosion of these lithium-ion batteries is often due to the purchase of fake and shoddy products, because the quality of the battery itself is not enough. However, some inadvertent details in the process of using lithium-ion batteries will also make your battery dangerous.
Twenty years ago, the fuel gauge IC did not appear. The earliest design was that the single chip microcomputer detected the battery voltage through the AD port to determine the remaining battery capacity. This method of voltage detection discharges the battery small current, and the battery power error is still accurate because If the voltage gradually decreases, just set a few fixed voltage points to judge, such as 100%, 75%, 50%, 25%, 10% voltage corresponding to several capacities...
After years of development, the lithium battery industry has formed a complete industrial chain with a high degree of specialization. Do you know how the lithium battery is made?
BYD: The blade battery can still discharge 90% at minus 10°C, with a mileage of 1.2 million kilometers
The battey as one of the most important parts of electric vehicles, batteries are also valued by major car companies. At present, there are mainly two types of batteries used by car companies to install vehicles: ternary lithium batteries and lithium iron phosphate batteries. However, BYD's blade battery (a new generation of lithium iron phosphate battery) was born, and car companies also have a more competitive battery option.
Both the camera drone battery and the mobile phone battery are lithium-ion batteries. The drone battery is the source of power for the device and has higher requirements for its safety performance. However, there is a difference between the two. The drone battery has a significant feature compared to the mobile phone battery --- high rate discharge. The drone battery needs a large current to discharge to meet the requirements of the drone in different environments. For example, in aerial photography, if a strong wind is encountered, the battery must be discharged with a large current to ensure the stability of the drone's position. Because of different requirements, the life of the camera drone battery is relatively short.
Polymer lithium ion battery is a kind of lithium ion battery, but compared with liquid lithium ion battery (Li-ion), it has high energy density, more compact, ultra-thin, light weight, high safety and low cost Many obvious advantages are a new type of battery. Below we detail the advantages and disadvantages of polymer lithium-ion batteries:
Generally speaking, the most common power batteries are lithium iron phosphate batteries, lithium manganate batteries, lithium cobalt oxide batteries, and ternary lithium batteries.
Why does the lithium ion battery capacity loss? Can the power loss of the lithium ion battery be repaired?
Lithium-ion batteries are the driving force of electronic products. If the battery consumption of electronic products is too large, the battery life of electronic products will be greatly reduced. Many users complain that the battery life of their electronic products is too short. If they are used for a long time, the battery life of the lithium-ion batteries of electronic products will be relatively weakened. The common problem of lithium-ion batteries in daily use is power loss. The more exhausted, the greater the battery loss.
The impact of high temperature on lithium-ion batteries, is high temperature the cause of bulging lithium-ion batteries?
Among all environmental factors, temperature has the greatest influence on the battery's charge and discharge performance. The electrochemical reaction at the electrode / electrolyte interface is related to the ambient temperature. The temperature rise means that the output power of the lithium ion battery will rise. The temperature also affects the transfer speed of the electrolyte. The temperature rises faster, the transfer temperature decreases, and the transfer slows down. The battery charge and discharge performance will also be affected. However, if the temperature is too high above 45 ° C, the chemical balance in the battery will be destroyed, causing side reactions.
