February 3, 20251 yr I’m new to this site. Please if topic already there share link. -Is the supercapacitor a replacer for batteries? Why or why not. -What size capacitor is equil to what size battery? -and other info please?
February 4, 20251 yr its a myth. supercapacitors was not/ will not ever be intended for long term energy storage like a battery. almost all of the "supercapacitor batteries" you see advertised as having ridiculous cycle life and charge/discharge numbers are in fact LTO cells - lithium titan oxide. A supercapacitor that can discharge 5kw/h of energy will be the size of a house.... a big house.

Why or why not. -What size capacitor is equil to what size battery? -and other info please? All the proposed uses I've seen for supercapactitors suggest that they are suited to applications where you will charge and discharge very often and need to do both very quickly. EG recovering braking energy in public transport vehicles that is then used to assist acceleration or pulling away from stops. They were also an early candidate for ERS systems in F1, but were either ruled out by regulations or were too bulky. Again this is an application where there would be frequent charge and discharge (2 minutes at a stretch for discharge, recharge and redeployment). So I don't think they are good for an application (EG a home) where you will charge up over a few hours during the day, maybe sit at full charge for a few hours, then discharge slowly over several hours once the sun has gone down. They don't even seem to be suited to EVs where, again, the expectation is a long charge followed by hours of some charging, yes, but a lot more discharging and not in bursts.
