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.

> It really should not be surprising that we can get very high recovery percentages from batteries -- we do not mine elemental lithium
Plenty of substances we don't mine elementally are not worth recycling. The main advantage with lithium is it tends to go into large volumes of standardised chemistries.
> 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.

What is the standard non-renewable resource used for the recovery process? What materials are used up as catalysts to convert it back?

Some battery recycling challenges are minimal volume at this point on the EV adoption curve, and LFP and sodium ion battery chemistries won’t be worth recycling for the materials alone (but still require recycling as ewaste).
The 90% recovery rate is not groundbreaking by itself. The real value is lower contamination and emissions—but it still needs to prove cost-effective at industrial scale.

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]
Can this be replaced with the original NHK World article?

I'm so tired of reading articles written by LLM. There are several sites that just ingest material (like studies) and crap out low-effort LLM articles.

The key point will be the energy inputs, and catalyst or other process input losses. Not the % recovery, its more recovery at an economically viable cost
Many processes could recover the inputs. Some are tremendously polluting. Cheap methods to recover lead from older lead-acid car batteries would be an example, or the way scavengers burn plastic insulation of recovered copper wiring.
TL;DR exernalities and economics and pollution drive recycling issues, not % recovery at this point. We know how to recover a lot of the inputs. Knowing how to industrialise and scale it up is what counts.
John McCarthy (of LISP fame) was an (in)famous curmudgeon on USENET, frequently used to say future generations will thank us for making giant collections in the ground of highly valuable recoverable industrial inputs, what we call "rubbish dumps" -He was only partially less wrong, but had a point to make about the cost of inputs to industry vs raw mining costs. If we do come up with a process to strip mine rubbish dumps and send feedstocks in the appropriate directions there's a lot there. Complex plastics, Metals, Organics, Acids, Methane Gas, you-name-it. We already collect and harvest the methane to drive other dump works, the idea of mining the materials isn't "wrong" as much as insufficiently economic right now against raw material sources.

“Japan”, as in the whole country developed this tech ?
I used to follow it closely and be in the industry, but it still seems like Japan is gonna be the last "mostly ICE cars" of the developed countries.
Which is a shame, because it has a perfect combination of short-range needs (I mean, look at kei-cars), tons of wonderful places to hang out while charging (toll-way rest areas are so good), rare sub-freezing temperatures in most of the country, mandatory vehicle inspections (which could collect great safety data as well as preventative maintenance), general love of new cars and brand loyalty, lack of political or individual divide of "big gas trucks are manly", mobile-power-station earthquake preparedness (a nice bonus), generally cooperative nation-wide infrastructure...
I guess we just have to hope the main automakers can hold on long enough for solid-state batteries and move faster than a snail's pace when it does.

Japanese automakers are excessively risk adverse. Last big risk by Toyota was their hybrid synergy drive, which they coasted on for too long.
Which seems strange since Toyota are the origins of JiT manufacturing. I wonder what made Japan go through a period of incredible innovation and then just decide "ok, that's enough".

I have a theory: Japanese car's have excellent reliability, their interiors and design are lacking. If every car in the world is an EV, which due to their relative simplicity tend to be reliable, what remaining unique selling points does eg a toyota have?

Solid-state batteries are facing production hell now, with lots of issues cropping up when tested at large-scale in real devices.
So they are not expected in meaningful quantities until the early 2030-s.
And the LFP chemistry has now advanced so much that solid-state batteries might not even matter anymore, except for some niche uses like aviation/drones.

It is curious - you would think they would love it? But they don't - is it simply the case of the Chinese beating them - stubbornness and pride? Or is there something more going on?
Toyota was seemingly decades ahead at one point with their hybrid cars; but now they have resigned to a defensive position compared to Tesla, Chinese automakers, even the European ones.

Toyota's first Prius (hybrid) came out in 1997 and Nissan's first Leaf (full electric) in 2010. Both Japanese, both ahead of the curve, now way behind it.
It is an interesting situation.
Anecdote: I have a 2014 Leaf, purchased a couple of years ago as the first foray into EVs. It's a great little car, perfect for the daily short trips for which we bought it. Use-case matters!

I remember BYD actually had to design models specifically tailored to the Japanese market (k-car)—their preferences are honestly so bizarre. I think a lot of this comes down to their national character. Once external momentum fades—like the industrial transfers from the US—they seem to lose the drive for technological innovation. They just cling to whatever they already have and refuse to adapt to global shifts.People in Japan are still using Yahoo and fax machines（not to mention their own bizarrely proprietary text editors,Hidemaru/SAKURA editor, to compare, in china, it's also vscode）.
Toyota is still digging its heels in on gas-powered cars, even though the fact that Tesla used Japanese batteries in its early days proves Japan was once ahead of the curve.but they always seem to retreat right back into their comfort zone after a brief flash of brilliance, watching the rest of the world race ahead while they continue living in the past.

That's probably a good thing, the world needs appliance-like cars for markets where EV charging isn't there yet.
Meanwhile Toyota is #1, moving millions of units, something like half of them are electrified in most markets. A 2026 Camry, for $30k, gives the buyer a low-TCO, value retaining, 50mpg, 230hp appliance of a car. That's a rarity.

Scientists found a way to extract up to 90% of oxygen from air! They call it “breathing”.
Lead acid batteries had a similar trajectory and modern lead acid batteries are effectively 100% recycled.
Plenty of substances we don't mine elementally are not worth recycling. The main advantage with lithium is it tends to go into large volumes of standardised chemistries.
