I read an article somewhere that discusses how Toyota has the most battery patents out of any company and also owns most of the solid state patents and are actually working on commercializing solid state batteries for vehicles.

The point I think the article was trying to make is that while everyone is focused on lithium ion, Toyota was biding it’s time and getting ready to one-up everyone with solid state batteries and vehicles with double the range.

No fire risk? hmmm ... but still on lithium 25 years later. But then again the recent advancements in solid-state battery technology have led to twice the energy density of traditional lithium-ion batteries as stated in this read, as well as eliminate the need for a separate anode altogether. Think its because it uses a lithium metal foil both as the anode and the current collector. But i don't understand the science behind why that would result in a more compact design.

Please share that article if you can find it. Sounds like an interesting take!

I honestly don't get the criticism Toyota has been getting recently. I think their decision to not go all in on just electric vehicles makes sense, especially for countries where it is highly unlikely that full EV will be a reality in the next decade.

I'm not sure about Toyota, because up till now they've been hydrogen evangelists and they don't have a great record on pure battery EVs.

Nice, when can we use them for phones and laptops lasting 72% longer and without fire risk? Genuine question, because optimistic battery articles have been popping up for decades, but here we are still with lithium ion in practice.

> here we are still with lithium ion in practice

Lithium ion batteries are actually amazing tech. I certainly remember the world without them; laptops had an hour of battery life, mobile phones were "car phones", everyone was running around paranoid about the "memory effect", and electric cars were an interesting curiosity always ten years away. Here we are today with pocket computers that last for days and electric cars buzzing around the city. In 30 years, some of this new tech we read about will be widely adopted, but in the meantime, it's not like things are that bad.

I think that electric airplanes will be the thing that new battery technology unlocks.

Because for a while it seemed they were going all-in on hydrogen fuel cell vehicles, a technology that makes little technological (and even less practical) sense.

They have always been conservative. They have the most reliable hybrid in the market.

Why is it called anode-free when it still has a copper collector with a special coating? Yes, they removed the graphite, but they didn’t remote the entire “anode”. Or is it because the collector and the coating are not technically considered as an electrode?

Isn't that a given since the invest in solid-state?

Solid state might share the fate of Betamax. There was a post a while ago about a small scale battery manufacturer named Amprius, which reported 500Wh/kg batteries: https://news.ycombinator.com/item?id=35276709 Thing is, the company is producing 450Wh/kg batteries NOW and they're planning on scaling up their manufacturing capacity to 5GWh: https://www.convertingquarterly.com/ConvertingQuarterly/Indu...

Some applications still require higher energy densities than what LFP can provide. Are you saying silicon anodes are more promising than solid state for those applications?
