Why no battery improvements

[crysilis]

i mean innovations in batteries have been incremental at best and i feel like we need better batteries

look at those drones that can fly for like 27 minutes

its stupid!

OK, suggest new materials for batteries that doesn't cost a kidney, can be loaded a considerable ammount of times and is suitbale for mass production

humans?

pigs?

Deer? we have a ton of them

[Waqas409]

Because its a tricky part and can not be experimented ( once its out for consumers )

Don't you see what happened with galaxy Note 7 ?

They are blowing all over the place.

What are you even talking about.

Liquid batteries are coming. So are organic. Problem is that making them usable in real world or taking build costs down is taking some time.

It takes more than a human being to understand. What the person is refering to is the KNOWLEDGE of the Gods.

put 10 whiny kids in bikes that have generators attached to them to charge your phone and laptop wirelessly

There's prolly a lot of stuff out there but it's just too expensive/inconvinient to produce for public usage. No Jetsons yet, folks.

 

My vision is some kind of device that captures electrons directly from the air.

 

For now ill stick to my army of hamsters on wheels.

If only we could harness the power of shitposts.

Whos to say behind the scenes the majors arent playing around with new tech for batteries?

They dont want the batteries to explode and take down airplanes, and burn down houses, like LiPo batteries do. I think they are focus on density right now, thats why we got 3.5Ah batteries. Once we reach 5Ah batteries with decent discharge rates ~10A and up then its a different ball game right there. Cans, not ziplock bags.

[flibberdipper]

Contrary to what you seem to think, research is being done on batteries that make Li-Ion batteries look like shit in terms of battery life, but they have to make sure they don't explode, wear out fast, can be recharged from partial charges repeatedly without wearing fast, as well as not being the size of a laptop.

just wanna mention that with the battery technology of yesteryear that drone would fly for all of one minute before dropping out the sky like a brick.

 

the motors on drone propellers draw a metric butt ton of power, a quadcopter i disassembled after *slightly too close contact with the ground* had a 72 watt motor on all 4 corners.

 

yes my friend, that is almost 300 watts just going into the motors, beyond that there's also the on-board electronics and communication, all coming from a battery pack that is smaller than your 80's brick phone.

From what I read. Li Ion Batteries are at the limit of what they can do. So now we gotta count on some one at a University or NASA or something to find a better way to make batteries.

with current lithium technology they basicly are.

 

that said, some lab has been experimenting with replacing one of the layers of the cell structure, more specificly the thickest layer, possibly -if this tech ends up coming trough in the state it is in its current experimental stage- up to 90% of space saved, in other words this newer technology could make li-ion technology 10x more dense (but it'd probably also mean 10x more unstabile because there's 10x more dangerous materials in one cell)
