Steingart: Early Tesla used laptop battery cells to avoid explosion risks
Dan Steingart · The Big Switch: Are Batteries the New Oil? · Apr 11, 2024 · at 18:01
Professor Dan Steingart of Columbia University explains why early EV designers pivoted from custom large-format battery cells to existing consumer laptop cells.

“Six years later, after all of these batteries catching fire, the initial team at Tesla said, let's just use cells that we don't know don't explode, which are cells that are in laptops. So the immediate predecessor to the cell that Brett took apart was used in a laptop.”

Steingart: Redwood, Ascend, and Li-Cycle rely on scrap exceeding 20%
“Currently, all three of these companies are living off of gigafactory scrap, which is exceptionally high, over, over 20%, as I understand it.”
Steingart: Battery recyclers will face a lean period as scrap rates drop
“I worry about the business case here because the gigafactories have every incentive in the world to minimize this amount of scrap, and so at the same time, we don't want batteries to die, so every recycler is going to have a lean period as scrap rates go down.…”
Steingart: Direct recycling is likely the only viable path for LFP batteries
“I think if LFP recycling is going to have a shot, it's going to be on a direct recycling route, and for those that know me and get a beer with me after conferences, they're probably doing a spit take, because I'm pretty skeptical of direct recycling in a lot o…”
Steingart: 5-minute charging batteries with zero explosion risk are likely impossible
“So the question is, is how do we have a battery that it gets us a 300 mile range that can be charged in five minutes that has zero danger of exploding, right? And that's probably Impossible, completely, but understanding how and why they explode is something r…”
Steingart: Grading spent EV battery cells for second-life applications is not bankable
“It's typically pretty, pretty difficult to justify the cost of grading these cells and estimating their second life. We do a fair bit of that in my lab, and I have to say to date, I think that, that it's probably not a bankable effort yet. I'm not sure that ev…”
Steingart: Battery recycling is a tolling operation without supply ownership
“I think the brutal truth is, is that it's a cost center, and that inputs, recycled inputs, are ultimately a tolling operation unless Redwood can pull off owning the supply. Because if Redwood can pull off owning the supply, then it owns the mine of the future,…”
