SHE Standard Hydrogen Electrode
EMF = cell potential = cell voltage = $\Delta$E
$\Delta$G = - (# of elctron) $\times$(farady's costant) $\time \Delta$E =
(standard reduction potential @cathode)[Volt] - (standard reduction potential @anode)[Volt]
"reduction potential" >0 easty to reduce (good oxdizing agent good for anode)
< 0 (like lithium)
$\Delta$G < 0 spontaneous battery or not
