Unlike conventional batteries, supercapacitors have an exceptionally long lifespan, lasting hundreds of thousands of charge-discharge cycles, whereas lithium batteries typically last only five years or less.
So, what’s the conversation rate between charge-discharge cycles and years?
I don’t know if the H2O2 is going to cause any problems, but if you have one of those ultrasonic type humidifiers and you do manage to dissolve the black goop, turning it on will just toss that goop onto all the surrounding surfaces.
