Day 2 of my EV series — the battery pack is basically thousands of tiny batteries, not one big one
Following up on yesterday's post about EV efficiency. Today's building block: the battery itself.
Most people (including me, before I looked into this properly) picture an EV battery as one massive block. It's actually thousands of individual cells — similar in basic concept to the AA batteries in a TV remote, just engineered very differently — all wired together into a pack.
Why this matters: almost every major story in the EV industry (cost, supply chain risk, which companies win) comes back to this pack — what's inside the cells, who makes them, and how efficiently.
Tomorrow's post goes into what's actually inside those cells (lithium, cobalt, nickel) and why a couple of countries dominate that supply chain. Following up here as the series continues.
