is very fast. Positive aluminum foil from the previous few years of 16um down to 14um, and then to 12um, now many battery manufacturers have been mass production using 10um aluminum foil, and even used to 8um. And the cathode with copper foil, due to its good flexibility of copper foil, its thickness from the previous 12um to 10um, then to 8um, to the present there is a large number of battery manufacturer

Do you often encounter the following situations when you have a love book? Meeting presentation ppt When the notebook is still 30%, but suddenly encounter no electricity embarrassment? The key moment in the game suddenly encounter battery power? Notebook just bought back less than a year time battery but frequent strike false power? Important issues such as business and office notebook but the time is getti

Generally divided into: 1, 2, 3, 5, 7, of which 5 and 7 are particularly commonly used, the so-called AA battery is 5, and AAA battery is 7! Both AA and AAA indicate the battery model. For example: AA is what we call battery 5. The general size is 14mm in diameter and the height is 49mm; AAA is what we call

Q: Does the cell phone charge have any effect on the battery? A: The answer is yes, while fast charging can improve the efficiency of cell phone charging, but also has an impact on battery life. As for why, we will introduce the following details here, with the answer attached here first. Q: Is the cell phone charged well or slow? A: If you look at it from the experience point

Laptops are now particularly popular, both outdoors and indoors, especially outdoors, where laptops are powered by batteries. For a long time, we will find that the battery's endurance is not as long as the beginning, before it can be used for 3 hours, now only 2.5 hours of endurance. What's going on? Shorter endurance, not a problem with the battery itself. For batteries that use less than 1 years, the duration of the

The ion battery protection circuit includes overcharge protection, overcurrent/short-circuit protection and over discharge protection, requiring overcharge protection, high precision, low power consumption, high voltage and 0 volt charging characteristics. The principle, new function and characteristic requirements of these three kinds of protection circuits are introduced in detail in this paper. Lithium battery
