Why do cheap batteries explode?

217 views

I hear a lot about e-bike and e-scooter batteries being a risk if bought cheaply whereas name-brands are better. I remember A Samsung Note phone having this problem as well. What causes this and how is it fixed/brought under reasonable control

It comes down to manufacturing standards. It’s incredibly important that a lithium cell be manufactured to a high standard because there’s a tremendous amount of energy should something go wrong.

Basically, if there is a problem with the separator, then a short circuit inside is likely. If a short occurs then it’s incineration time.

Poorly made cells will take less abuse before failing catastrophically.
