How much do you know about the battery electrode binder
Apr 07 , 2021
Electrode binder is one of the important auxiliary functional materials in lithium-ion batteries. Although it has no capacity and occupies a small proportion in the battery, it is the main source of the mechanical properties of the entire electrode. The electrochemical performance of the battery has an important influence. In addition to the bonding properties of ordinary binders, the electrode bi...

What’s the function of lithium battery formation?
May 08 , 2021
A lithium-ion Battery formation is activated by a single charge just after it is produced, similar to the way a floppy disk is "formatted". The battery can only start charging and discharging normally after the transformation is completed. The principle is simply that the first charge of the battery activates the active material inside the battery and creates a dense film on the surface of the ano...

Why did the PACK plant need buy a battery sorter?
May 14 , 2021
When the lithium battery cell leaves the factory, the cell factory will carry out capacity test on each cell, so as to divide the cell into three grades: A,B and C. Then on what basis are they divided？ Class A: capacity, size, internal resistance, voltage and other parameters can meet the standard and excellent performance of the cell is generally defined as class A. Class B: the capacity, size, v...
