Lithium ion 18650 & Li Po Battery Production Process is complicated

- Nov 01, 2017 -

The production process of lithium battery is quite complex. 


It can be roughly divided into three sections: 

pole making, battery unit (battery cell) making and battery assembling. 


Lithium battery pole piece manufacturing process comprises:

electrode slurry preparation, electrode paste coating, rolling, cutting, electrode welding processes; 


lithium battery manufacturing process including:

winding or lamination, casing and packaging, vacuum packaging and injecting electrolyte, etc.; 


the battery assembly process mainly includes:

formation and partial volume, assembly the test, etc.


all seems simple, but there are too many points need to be taken care with. otherwise, battery is apt to cause dangerouse problem during using.
