EV batteries are central to every electric vehicle. They determine range, charging performance, efficiency, durability, weight, and a significant share of the vehicle's cost.

This article series explains how EV batteries work, how they are designed, how they age, and which technologies are shaping the next generation of electric vehicles.

Some chapters are written as core explainers, while others are deeper technical dives. If you mainly want to understand what matters for EV ownership, start with the core chapters and return to the advanced topics later.
