IntroductionLaser engravers have become essential tools in various industries, from arts and crafts to industrial manufacturing. Traditionally, these devices rely on direct power sources or large, heavy batteries, limiting their portability and versatility. However, with the advent of18650 lit...

IntroductionChoosing the right lithium battery for an end product is a critical decision that directly impacts performance, durability, safety, and user satisfaction. With various lithium battery types on the market, each designed with unique characteristics, understanding the factors that influence...

1、 Basic concepts and structures of ternary lithium batteriesTernary lithium battery is a high-performance lithium-ion battery with advantages such as high energy density, long cycle life, and good safety performance. It is widely used in fields such as electric vehicles and energy storage systems....

The magnitude of the parallel short-circuit current of lithium iron phosphate batteries depends on the rated current and quantity of the batteries.The calculation formula is: parallel short-circuit current=maximum battery current x number of batteries.For example, if the maximum battery current of a...

Fully charging a lithium iron phosphate battery to 100% is better than charging it to 90%, and it is advisable to fully charge the battery at least once a week. There are some differences between it and ternary lithium batteries. For ternary lithium batteries, it is sufficient to charge them to 90%...

In the charge-discharge testing or actual use of lithium-ion batteries, the voltage parameters mainly include plateau voltage, median voltage, average voltage, cut-off voltage, etc. The typical discharge curve is shown in Figure 1.The plateau voltage refers to the voltage value corresponding to the...

Many people think that as long as the unused lithium battery packs are stored away, they can still be used normally in the future. However, this is not the case. Even if lithium batteries are not in use, they will discharge at a rate of 0.2% to 0.3% per day. Moreover, after being stored for a period...

Storing Lithium-ion Batteries at the Appropriate TemperatureThe typical storage temperature range for lithium-ion batteries in a household or storage unit is usually suitable for the safe storage of lithium batteries. The safe storage temperature range is quite wide, as shown in the following table....

I. What is the Production Serial Number of Lithium Batteries?The production serial number of lithium batteries refers to the unique code assigned to distinguish similar products during the production process. Through the production serial number of lithium batteries, information such as different pr...
