Channel: ME and the Battery
Date: 27/06/2021

Lithium ion batteries are regularly in the news because of individual batteries catching fire. But most people don't know, what mechanisms are in place to keep batteries safe.

In this video, you will learn what the Positive Temperature Coefficient (PTC) element is, how it works and why it is important to prevent battery fires and explosions. Additionally, you will also learn when it does not work.

Throughout the video, I am referring to the following papers and resources:
