Episode 051 - What’s Really Inside a Battery? | EV Manufacturing, Defects & Gigafactories | Dan Brett

EV batteries, manufacturing, defects, and gigafactory scale explained.

Battery production is scaling fast — but how much do we actually see inside the cells being produced?

In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Dan Brett (CEO of Sention Technologies) about EV battery manufacturing, lithium-ion battery defects, and how gigafactories manage quality at scale.

We cover where defects come from, why many issues only show up later, and how new diagnostic approaches like ultrasound can help detect problems earlier — across R&D, production, and second-life batteries.

The conversation also explores scrap rates in gigafactories, energy use, battery recycling, and the broader supply chain challenges shaping battery production in Europe and globally.

A grounded look at how battery manufacturing actually works today — and what changes when you can finally see inside the cell.
