The internal structure of the 18650 lithium battery cell
Lithium battery positive electrode
The exterior of the 18650 lithium battery is wrapped in a metal casing, and the battery cells inside can be seen if the casing is destroyed
Negative electrode of lithium battery cell
There are blue plastic insulating gaskets on the negative pole and positive pole of the battery cell
When we disassembled it, we found that the cylindrical 18650 battery cell is wrapped in a full metal casing, which can protect the internal materials very well and prevent liquid leakage.
Inside the cell, the film soaks the electrolyte
The inside of the 18650 lithium battery cell is a roll of film, and the two ends of the battery cell are respectively designed with positive and negative electrodes. The internal film is a specially formed polymer film. The film is designed with a microporous structure, which allows lithium ions to freely shuttle through it.
