The article is very, very light with details. The university or research center is not named. No scientist is named. No link. Nothing that tells "look, we're telling you real, solid, serious stuff."
It really should not be surprising that we can get very high recovery percentages from batteries -- we do not mine elemental lithium, so the processes we use for extraction are already designed to extract lithium from fairly low-purity sources. In contrast, lithium batteries are an incredibly high-purity source of lithium. The main question is when it will become cost-effective to create recycling pipelines.
Lead acid batteries had a similar trajectory and modern lead acid batteries are effectively 100% recycled.

The article seems to be very unspecific about what it is this company does that is so different. It also steps over the fact that there are already quite a few companies active in the US, EU, and China that are recycling batteries. Nor is the cited percentage that remarkable. That's ballpark what competitors are achieving as well. Probably a bit more. 10% lithium is a lot of lithium to not recover. Most natural deposits of lithium have very low concentrations of it.
The main thing actually holding back the recycling industry is the lack of batteries that need recycling, not the lack of technology needed to recycle them. Most of the batteries produced in the last ten years are still being used. And quite a few might head for a second life in storage for another decade or so. It's probably going to be another decade before recycling hits a scale where it becomes a significant and lucrative source of valuable raw materials.
And as others mentioned, it's not just about recycling the lithium in batteries. It's not like cobalt, nickel, copper, graphite, etc. end up on the trash heap.
So this isn't groundbreaking results and the article itself is of questionable quality without sufficient detail as to why this is a newsworthy result. How is this the top rated article on hacker news? A more meaningful example would have been the paper that sets out a scalable and cost-effective route for closing the loop on LFP materials, while demonstrating that high-yield lithium recovery and environmental responsibility are not mutually exclusive: https://www.sciencedirect.com/science/article/pii/S092134492...
> The industry standard for the recovery of lithium (remember there is a difference between recovery and extraction) is 90%, with some platforms now achieving 95%+ like those that use carbonation.
Japan was one of the first countries to be hit with rare-earth export-restrictions by China - going back to 2010. It seems that a lot of policy came out from this unpleasant shock, incl. the decision by Toyota to focus on developing FCEVs which would be less dependent on Chinese supply-chains. Ironically, the resulting vacuum may have actually led to Chinese/American companies gaining market share in the BEV space.
Still, given how things are going, FCEVs (and Japan with it) might actually end-up having the last laugh.

Incidentally, companies developing technologies for reusing EV batteries in grid storage applications (where even <80% capacity EV batteries are just fine for many years), have trouble getting enough EV batteries, because they last much longer than we were made to believe.

Can this be replaced with the original NHK World article?

This article is poor, because lithium is just one part of the value contained within EV batteries. Far more valuable is any nickel, cobalt and graphite. Equally valuable is any copper and aluminium. Unless you're effectively recycling a significant number of the major materials, it's not enough.
Furthermore, it's not a remarkable achievement. By contrast to this headline, Redwood Materials claims "Redwood’s technology can recover, on average, more than 95% of materials like nickel, cobalt, copper, aluminum, lithium and graphite in a lithium-ion battery."[0]

Here is another article with that details : https://www.techspot.com/news/112051-japan-finds-way-recover...
