Battery boom or comment doom?
Japan develops a method to recover up to 90% of lithium from used EV batteries
Amazing battery recycling breakthrough — but the comments are in full roast mode
TLDR: Japan says it can recover up to 90% of lithium from old electric car batteries, which could cut waste and reduce reliance on imports. But commenters were far more interested in roasting the article, questioning the hype, and arguing whether the breakthrough is actually new.
Japan may have found a way to recover up to 90% of the lithium from old electric car batteries, which is a big deal because lithium is one of the main ingredients that makes those batteries work. The pitch is simple: less waste, less mining, less dependence on imports, and even lower planet-heating pollution. On paper, it sounds like an Earth Day mic drop. But in the comment section? Absolute chaos.
Instead of celebrating, readers instantly turned into editors, fact-checkers, and professional side-eye specialists. One of the loudest reactions was basically, is this breakthrough real, or is this article just badly written? Several commenters dragged the write-up itself, with one flatly declaring, "What a poorly written article," while another demanded the original NHK World report instead. Ouch. Then came the semantic pile-on: people questioned whether saying "Japan developed this tech" made it sound like the entire country put on lab coats and got to work.
And of course, no internet thread is complete without a fight over the numbers. One commenter pushed back hard on the headline-worthy 90% recovery claim, arguing that this may not be as revolutionary as advertised because similar systems already hit that range. Another tossed in a blunt hot take: "why bother? japan hate EV". So while the science could genuinely matter for the future of cleaner cars and supply chains, the community mood was less "wow" and more "citation needed, and also fix the headline".
Key Points
- •The article says a recycling facility in Japan developed a method that recovers about 90% of lithium from used EV batteries.
- •It states that conventional methods often recover less than 50% of lithium from used batteries.
- •The reported process replaces standard sodium hydroxide with recovered lithium hydroxide during recycling.
- •The article says the method could reduce carbon emissions by roughly 40% compared with conventional recycling techniques.
- •It notes that only about 14% of used lithium-ion batteries in Japan currently enter official recycling systems, while expansion is planned through 2027 and 2035 targets.
