We ranked 3 types of EV batteries to find the most efficient and sustainable one

Amidst the booming influx of electric vehicles worldwide, automakers and tech companies have been focusing on optimizing the most vital and expensive part of EVs: the batteries. They aren’t all alike, and manufacturers use a range of different kinds of batteries. So we’ve decided to select and rank the three most prominent (or promising) battery types: lithium, solid-state, and sodium-ion batteries. We’ll compare the batteries using four criteria: safety, energy density and charging time, sustainability, and price. But before we begin, let’s brush up the basics we need to know. How do the battery types differ? Lithium-ion and solid-state batteries…
