Batteries play a vital role in our lives. They are used to store electricity and power various electrical appliances. Especially lithium-ion batteries, they are used in a wide range and are often used in some small portable appliances, such as mobile phones. The battery is a consumable material, and it is often charged and discharged. No matter the battery is the best, it has a certain lifespan, and the price of lithium-ion batteries is higher than other batteries, so try to choose good quality lithium-ion batteries when buying, and the service life can be longer , Then how do we detect the quality of lithium-ion batteries?

Due to the wide application of lithium batteries in portable electronic products, coupled with the continuous expansion of the demand for lithium batteries in the electronic product market, many large and small lithium battery manufacturers have been born, and which brand of lithium batteries is good has become an electronic product buyers often have to consider issues, because the quality of lithium battery brands will directly affect the competitiveness and survival cycle of their end products in the market and the space for profit.

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?

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.

The INRUSH PEAK discharge current and continuous discharge current mainly depend on the battery cell. The overcurrent protection of the protection board only sets a safe discharge current parameter for the battery. If the battery works within this safety parameter, no safety will occur. (but if the discharge current exceeds the load current of the cell allowed, it may also shorten the battery cycle life)

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:
