EV batteries aren't disposed of, they're reused as stationary storage, then recycled, with over 97% of the raw materials recoverable to put into new batteries as of 2021. Redwood Materials recycles over 60 tons of them per day, and has another facility opening in 2023 that can handle an additional 125,000 tons per year. The materials are too valuable to throw out, so a market for reusing and recycling them has existed as long as li-ion electric cars have existed.
