quote: And not every modern battery can get charged with 1C. That's just wrong!A Li-Ion battery with 3.7V and 1Ah has a energy of 3.7Wh!So if you charge it with 1Ah for one hour, it's almost full.
quote: The same if you put 3.7W in it in one hour it's full, too. (for example by connecting it to a 3.7V 1Ah power source)It's nothing different, it's the same, expressed in a different unit.
quote: Are you joking with me? Why should you charge a SC above it's rated voltage? Why do you connect it to a battery at all?
quote: The idea is to replace a chemical battery with a SC in future devices, nothing else. And she never claimed anything else. Just read her paper:
quote: The kilowatt hour, or kilowatt-hour, (symbol kW·h, kW h or kWh) is a unit of energy
quote: The watt is a derived unit of power in the International System of Units (SI), The unit, defined as one joule per second, measures the rate of energy conversion or transfer.
quote: Nobody who knows what they're talking about is going to be referring to battery capacity in W/H.
quote: If you have a typical 12V battery and a 2V "super" capacitor, the battery will overload that capacitor.
quote: No, that's not the idea. Capacitors were never intended to replace batteries and never will
quote: however battery technology may advance further as new designs allow them to store more energy, perhaps even generate energy by means of a chemical reaction.
quote: It's not really her paper, is it? Not that it matters because until she has a functional prototype it's all just conjecture
quote: My last reply to your ignorant dumb posts:
quote: Watt is not a unit of energy . Watthour is a unit a energy . And I never used Watt/hour (W/h) as you constantly did, I always wrote Watthour (Wh). If you don't believe me, then take a look in your physics school book, or
quote: So again, Wh (Watthour), because Wh is a unit of energy, gives you the amount of energy stored in a battery!
quote: I never wrote W/h, I always wrote Wh and pointed you, several times, to this fundamental mistake you constanstly did.
quote: Of course, if you're an idiot you can bring everthing to explode. But it's a fact, a supercapacitor does not need a charging circuit, just a constant voltage (of course the correct voltage). That's all I said. Everything else you wrote came from your wrong imagintation.
quote: That's exactly the use case of a super capacitor: To replace a chemical battery!
quote: chemical batteries (ni-mh, li-ion) store the energy chemically, they release it with a chemical reaction!
quote: It's what SHE wrote. It's her work! You must be really jealous.
quote: She also build the prototype, shown in the picture of this article, produced in the lab with a Prof supervising her (of course wasn't she allowed nor able to produce it totally on her own)quote
quote: Amps are the units of electrical energy a battery has "available for transfer" and volts tell us the rate of said energy transfer.
quote: Being a derived unit doesn't make them any more conceptual than these base units.
quote: and for the last time, stop using W/H as watthour, it is not watt per hour, check your electricity bill if you ever get confused about the units again, seriously...
quote: Watt is not a unit of energy . Watthour is a unit a energy
