That was a very vague article.

"Our guys have made a battery thats...well...already a thing...We haven't really mentioned that they've overcome the problems that have yet to be overcome, just focused on what is already known about the battery type. However here's an unhelpful graphic. However they're better! In every way! Invest, invest! They did it guys! This is the next big thing!"

I clearly remember that scene from my childhood for some reason, but absolutely nothing else about that movie. Not even the movie name. I always thought the scene came from Robocop or Judge Dredd or something. It reminds me of the arm pulling scene of the big robot of Judge Dredd.

Also I love Malcolm McDowell. He's always fantastically menacing.

It's only useful if it can be mass-produced. Many of the new battery techs have been unable to scale meaningfully outside of a laboratory unfortunately.

I'm not quite so cynical as the other person, but I think it's really easy to see only the potential of your new battery technology and not the negatives that will impede development.

We're really just throwing around "Holy Grail" at this point. Lithium mining is an environmental debacle. If the energy-density issues could be overcome for a sodium metal battery... well, now that's holy-grail-esque.

Sooo, using even more lithium? It's unfortunate that the deposits are generally bound with actinides and other nasty.

A lot of this. Mainly due to financing, a multitude of competing technologies - a major one being continuous improvements to Li-Ion.

One thing TFA mentions that bears repeating- we are getting better at making Lithium Ion batteries every year. Improving chemistry, reducing the amounts of rare elements they require, reducing production costs, speeding up charge time. 1 kWh of LI battery cost $1000 to make ten years ago. Now it's more like $120. Projected to continue to fall over the next few years to the point where the EV version of a car will cost less than the ICE version.

If we manage a revolutionary new battery that blows LI tech out of the water that's great but present day LI tech is itself far beyond where we were a decade ago.

Notice how they don't mention the capacity of these long-lasting batteries, so we can tell whether you get more overall power output?

If they last 20 times more cycles but hold 20 times less power then there is no gain

They are more energy dense than lithium ion and require less of the temperature management infrastructure that lithium ion needs. So net-net, the batteries systems are smaller and lighter for equivalent total capacity.

That's the most important thing these days, energy density. Although batteries are becoming more energy dense than some explosive, dynamite for example.

So what I'm hearing here is you could make an electric bomb.  A device that, once plugged into some kind of trickle-charge source... like a USB port on the back of a computer... waits until it's fully charged then detonates.

Totally safe until you plug it in.

That would be effortless. Lithium Ion batteries are already that. The reason they don't explode in general is because of extra circuitry called a BMS (battery management system) that monitors the voltage of the cell and stops accepting power once it hits 4.2V. It's the same reason why you shouldn't use any old wall plug with the right voltage and should use a "Lithium ion charger" if that's what you originally had because they often have a BMS inside them (these are easily identified by the charge light that turns off once the battery is charged).

Your device could be made with these two things, tape to hold them together and two wires.

They don't explode per se, they combust. Think the Tesla car fire.

So any size could take out a small shack, just need something to catch fire where it creates it. Like the people who charge their phones under their pillow and burn down their house.

Sorry, I'm kind of invested in an electric bomb, not an electric ignition device.  I've seen camera flash capacitors make a bigger 'boom'!

Not to say that flare up isn't impressive, it's just not what I expected after hearing about the high energy density and the rapid charge rates.

¯\_(ツ)_/¯

Won't get that out of lithium ion. The energy release is high heat for a [long] period of time. Eg the EV fires tend to burn for several hours.

Probably need a gas or something that can release its energy in a short period of time. Maybe tape a lighter to the thing earlier?
 
2021-05-18 9:32:53 PM  

dyhchong: They don't explode per se, they combust.


Explosives don't explode either, they also just combust.

What makes them explode is if you make that combustion happen in a restricted space.

It is the difference between a fire, a firework rocket engine, a gun, and a bomb. They all can use some form of black powder, two allow the gas to escape, one into the open air, the other from a small hole, the other two force the burning to happen in a restricted space to create explosive force.

If the gun is poorly made and has a lot of combustibles in it, it too can explode. If you design a device full of black powder which has no way for the gasses to escape quickly enough then congratulations, you have made a bomb. Light the fuse and run quickly away.

You can get the same amount of those same combustibles and throw them loose on a fire, and they will burn quite safely.

I was more thinking of old school chemical batteries, not rechargables in my OP.
