Popular Science explores the most common battery types used today by automakers: NMC, NCA and LFP.

Underneath the hood of an electric vehicle is the car’s battery pack. That lithium-ion battery is where the car stores all its energy. While they might all look the same, there are some big differences between them.

We worked with Pop Sci to explain how building batteries made from more abundant materials like iron, allows batteries to be more cost effective, more sustainable and more durable than batteries that rely on critical materials like nickel and cobalt.
