Rechargeable Batteries

Postby Garrett_Reynolds_1D » Wed Feb 01, 2017 7:35 am

I have heard that fundamental battery we know today is inefficient because of its size, and I agree. Take a laptop battery for example, it is essentially a brick. Obviously we have just been introduced to Electrochemistry and now understand how a rechargeable battery works. Does anyone know or heard of research or any process in shrinking the battery? I am assuming the method of producing a current the way that was taught in Monday's lecture wouldn't be applied. Thanks.

This article seems pretty cool:
"this new battery could allow for wireless devices to transmit their signals 30 times farther — or, perhaps more usefully, be equipped with a battery that’s 30 times smaller. If that wasn’t enough, this new battery is rechargeable — and can be charged 1,000 times faster than conventional li-ion batteries" ... mes-faster

This recent article introduces many new solutions to bulky and quick-dying batteries. This includes gold nanowire batteries (nanowires, a “thousand times thinner than human hair,” could produce batteries that don’t die), nano “yolk” triple capacities (triples current battery capacities with no additional bulk but charges in 6 minutes), and NTU fast-charging batteries (smaller than a dime but charges to 70% in 2 minutes).

In addition to that, research is also being done on lithium-air breathing batteries (using air instead of a material as an oxidizer), fuel cells for phones (only needing to charge once a week), aluminum graphite batteries (fully charges a smartphone in 1 minute), and skin power (producing electricity from a person’s skin). Looks like we have a wonderful technological future ahead!
