Can anyone explain why the popcorn graphine acting as the anode and cathode would increase capacity and speed of charging, but not speed of discharge?
Looks tasty.
BTW, replaced the standard sealed lead acid starting battery in my Harley-engined bike with a battery based on A123 cells (lithium iron phosphate). Battery went from 14.5 pounds to 2.25 pounds, significant weight loss on a motorcycle.
Surface area, conductivity of the electrodes, and the ability to reject heat during charge and discharge cycles.
Cell charge and discharge rates are limited by their internal resistance, which can cause too much heat to build up within the cell, limting efficiency, and causing cell damage and failure.
That is bad with a lead-acid cell. It’s really, really, really bad with a li-ion cell.

The circuitry being fed determines how much draw there is. You have a number of outlets running from the same circuit breaker but the actual draw is determined by the number/type of devices plugged in.
Curious if it looks anything like...
‘....significant weight loss on a motorcycle.”....
Or anything else using stored batteries
If not already available, I would like to see someone come up with a miniature battery charger, perhaps solar that one carries on their person and provides the ability to charge a phones battery while they are moving about with no access to other charging capabilities. Anyone know of such a device?
In my pants pocket?
Uh, no.
If they could actually do this they wouldn’t be telling the world their secret.
Is the price of silver threatening to rise again?

Nothing wrong with a faster discharge. It provides more amps for torque sensitive equipment.
“60 degrees Celsius? In my pants pocket?””
Reminds me of the time I learned not to carry a 9V battery in a pocket with coins.
