AquaMetals CEO Steve Cotton discusses the projected market expansion for lithium battery recycling.
Prediction Open · timeframe Mar 2044
Cotton: Recycled lithium content will reach 80% to 90% in decades
“More and more recycling infrastructure gets built. We get closer and closer and migrate from that less than one percent to 80 to 90%, just like what lead has shown us. And it's really only a couple decades of recycling, so it'll happen fairly quickly.”
Opinion
Cotton: Traditional battery smelters are dangerous, unsafe hellscapes
“You know, having the desire to understand, well, what happens to these batteries, I went to smelters, and they're a hellscape. It's very dangerous. You've got lead dust all over the floor. You've got a bunch of people wearing hot suits literally chucking batte…”
Insight
Cotton: Processes generating more waste than recovered material aren't true recycling
“When you produce many multiples more waste and pollution than the valuable materials that are recovered, is it really even recycling is the way we look at it.”
Assertion Contradicted
Cotton: Under 1% of materials in new lithium batteries are recycled
“And if you contrast that today to a new lithium battery that you get regardless of the application, whether it's an EV or a piece of consumer electronics, et cetera that has under one percent of the recycled lithium, nickel, or cobalt in that new battery. It a…”
Assertion Partly supported
Cotton: Pyrometallurgy burns or loses lithium into unrecoverable slag
“That really is high temperature, fossil fuels based and it doesn't recover all the materials. For example, in lithium recycling you burn the lithium or you lose what lithium you don't burn into what's called slag, which is a solid waste stream that you can't r…”
Assertion Not checkable as stated
Cotton: Hydrometallurgy requires massive chemical inputs and costly waste management
“And it's not really great when it comes to the environment or worker safety. You've got train loads of chemicals coming in. So the economics of, ah, managing that, storing those in massive tank farms, and then spending tens of millions of dollars to run a tras…”
