Earlier quoted context omitted.

Yes but Li-ion was first, so that's what you now have to beat (including the ways in which world has adapted/overcome its shortfalls).

Are you kidding me? The 'first' was the Voltaic pile, copper and zinc. The first practical rechargeable was lead-acid. Li-ion is a relative newcomer, but had a sufficient power density to lead to a lot of applications which in turn led to a lot of research on improving Li-ion in a virtuous circle. We are pushing the limits of Li-ion and know that is sucks for some environments or application requirements, which is wh…

I believe sambe was using “first” in the same way you did, i.e. first of the two

---------------------------------------------------------------- Dear battery technology claimant, Thank you for your submission of proposed new revolutionary battery technology. Your new technology claims to be superior to existing lithium-ion technology is is just around the corner from taking over the world. Unfortunately your technology will likely fail, because: [ ] it is impractical to manufacture at scale. [x]…

Sure it's a funny checklist but not very useful since it can be used to dismiss anything. Coal can generate a lot of electricity even in the dark or in the gentlest of breezes yet we still develop tech for solar or wind power.

as it should be. Energy is about hard sciences, not technology, and so progress is very unlikely and thus slow, much slower than the claims about breakthroughs.

From the title

In the first line

> ... making it a candidate for use in satellites and industrial machinery.

So 2/3 of your points don't really make sense

BTW: Whatever happened to those fuel cell proposals promising to replace laptop batteries altogether? I remember pictures of laptops running on working prototypes claiming to achieve 10 hours run time on a single "charge" 10 years ago.

EDIT:

Actually that's 17 years ago:

From the company website: "Hitachi Zosen is promoting development into an all-solid-state lithium ion battery that is anticipated as a post-lithium ion battery applicable to next-generation cars. We have developed an original manufacturing method that has successfully created an all-solid-state battery without the mechanical pressure conventionally used during charging and discharging. Our battery maintains a high le…

We have developed an original manufacturing method that has successfully created an all-solid-state battery without the mechanical pressure conventionally used during charging and discharging.

This is my litmus test for new battery technology. If they have a manufacturing process and it's already implemented then their proposition can(but doesn't necessarily have to ) be treated seriously.

Let's see how much capacity can be squeezed out of this. I don't suppose it's too impressive though - solid state batteries only recently started visibly improving in all the interesting parameters.

This probably isn't the company to produce it, but it does look to me like solid-state lithium batteries are the next step forward in battery technology. Probably hitting mass-market production in at earliest in 2022 as far as I can see.

Longer term, my read is that fluorine-ion batteries are the most promising potential generational leap. But that these are only likely to be viable in solid-state form, as fluorine is more dangerous than lithium.
