    新材料電池理論容量/理論能量密度計算

    以鎂碘電池為例


    The Gibbs formation energy of MgI2 at standard conditions (298 K, 1 atm) can be calculated (data from NIST webbook)



    Complete I2 reduction is accompanied by 2 e transfer per . Therefore, the theoretical capacity of I2 is


    The electromotive force (e.m.f.) of the Mg/I2 battery is


    The theoretical energy density of I2 cathode is


    The theoretical energy density of the Mg/I2 battery based on the total electrode mass is

    1. Did you know there's a 12 word phrase you can say to your man... that will trigger intense feelings of love and impulsive attraction to you deep inside his heart?

      12 Words Who Trigger A Man's Desire Response

      This impulse is so hardwired into a man's mind that it will drive him to try harder than ever before to take care of you.

      Matter of fact, triggering this powerful impulse is so important to having the best possible relationship with your man that the instance you send your man a "Secret Signal"...

      ...You'll soon find him open his heart and soul for you in a way he haven't expressed before and he'll see you as the only woman in the world who has ever truly attracted him.
