EP 28 - 18650 Battery Teardown & Comparison
Channel: Dielectric Videos
Date: 30/04/2017

Today I take apart two 18650 lithium-ion cells to show you what's inside. Both cells have been discharged to 0V to prevent fire. One cell is a genuine LG HG2 18650 cell, and the other is a no-name cell with notably higher internal resistance.

Do not try anything you see in this video at home unless you are willing to accept the risks associated with disassembly of lithium batteries. The chemicals found inside these cells can be hazardous, and improperly discharged cells can present a high fire risk if punctured or dismantled."

Thanks for watching!
