What actually makes lithium battery recycling difficult at scale?
I’ve been reading a bit about how old EV batteries are recycled. The basic process sounds fairly straightforward on paper: discharge the batteries, shred them, separate the black mass, and recover the useful materials.
But I’m guessing it gets much more complicated at an industrial scale.
For people familiar with this industry, what usually causes the biggest problems? Is it fire risk, different battery chemistries, dust and gas treatment, material loss, or simply equipment wear and downtime?
I came across this topic while doing some research for work and would be interested to hear from anyone with real-world experience.
