I don't care to understand how to measure it, just want to understand how it works. First help me understand how a basic rechargeable fluid battery system works. Please understand i have an 8th grade education, a ged, and some tech school. I had to teach myself alot. How i understand it after reading alot. Within the battery is posotive and negative ions. When a copper wire is introduced, touching - and + ends, -ions flow to the +end of battery, pass their -charge through the wire. (becomming atoms?) Positive ions flow toward the -End of battery, picking up the -charge from the -end of battery.(becoming atoms?) I'm sure i'm wrong, because i think i remember reading that molecules disolved in a solution kinda break apart and become negative and positive ions(depending on the molecules and possibly solvent) So also...can atoms exist in a liquid solution in which they are soluble? I did thing the electrons flowed through the wire, but then read on here that it dosent really flow, it passes chage, as in the electron is jacked up into a higher orbit, or has more energy, and passes the higher energy alog. So if i alter my understanding with that i come up with.... Charging the battery would be passing the high energy state to the electrons in the -ions in the battery. Using the energy would be using the extra energy given to the electrons(from charging) within the -ions, while the posotive ions never loose energy. Is that close?
