---------------------------------------------------------------- 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]…

As history has shown w.r.t spam, the stuff eventually gets sorted out I'm sure people could have come with similar criticism for li-ion batteries, before them took over

Not only that, if this battery had been available first then the attack on someone pushing Li-ion would have been:

[x] it lacks thermal stability at low or high temperatures.

[x] it is too likely to catch fire or explode.

Too many people think Li-ion is magic, when it just happens to occupy a particular niche of characteristics that let it get a good early jump in the race for portable power. Nothing about the chemistry involved mandates it remain in a position of primacy.

> Those used in smartphones offer a capacity of thousands of milliampere per hour. Capacity is measured as a product of current and time, not current per time.

I guess the inclusion of "per" there was a typo?

They used the correct units earlier in the article.

also, dear technology journalist:

[x] your description uses milliamp hours and milliamps per hour interchangeably

[x] milliamp hours is a useless metric when we don't know how big/heavy said battery is

[x] milliamp hours is a useless metric when we don't know the battery's voltage

Without talking in terms of energy (Watt.hours) it's impossible to compare with existing batteries. mAh is only useful when comparing the same battery cell chemistry, as the voltage is the same. This battery could be lower or higher voltage - making 1000mAh more or less energy than an equivalent existing 1000mAh battery.

Does anybody know the voltage, size, and weight? Without those numbers, “1,000 mAh” is meaningless. A single AAA battery is rated the same, and if you managed to find an even smaller battery, you could “invent” a 1,000 mAh battery out of it by duct taping a few together.

Yet another example of a glib response ignoring the actual facts in the article and ironic to boot given that lithium-ion suffers from several of the flaws listed. The funny thing is, none of the claims you make are correct and you miss the point where this tech is specifically designed to cover areas where Li-ion fails (like high temp and places where having a battery explode into flaming debris is a bad thing.)

I’m just curious, is there any time when having a battery explode into flaming debris a good thing? :)

A little extra kick during staging for Rocketlab :)

Why in the article do they state the capacity as 1,000mA instead of just 1A?

I'm curious why you made a new HN account just to write that comment.

Some people seem to create a new account for each story they comment on so they or their comments can't be 'tracked' between stories.
