Wild claims? “‘We did this thing in the lab.’ It could be a breakthrough provided they can scale production.” The only thing that would make this a wild claim is if they didn’t actually do what they said or if it didn’t work like they said. They didn’t even claim this could be commercialized.
Also, Professor Zhao works at Western University, in Ontario, Canada. Here’s an article about this same research on their website. The only reference to CATL in the article you linked mentions that they are commercially producing sodium ion batteries using a different process.
Public buses in areas of China trialed these batteries and they didn’t live up to their claims which is they can be bought on Alibaba second hand. I don’t have the “energy” to find the articles in English as it’s out the scope of my original comment anyhow. It’s not just claims around CATL batteries, it’s an industry-wide problem.
