1
New cards

Coulombic efficiency, CE =

discharge capacity of cycle n / charge capacity of cycle n-1 = power out on current cycle / power in on previous

2
New cards

Gibbs phase rule

P + F = C + 2; P = electrochemically active phases, F = dof, C = chemical components, 2 = constant T and P

3
New cards

Chemical driving force

DeltaG_r = -zFE, z = ionic charge, F = Faradays constant, E = voltage between electrodes, deltaG<0 = spontanious

4
New cards

Specific capacity

Q_grav = nF/M*3.6, n = ion valence*no of ions in formula, F = Faradays constant, M = molar mass, 3.6 = conversion to mAh

5
New cards

Cyclic voltametry hysterisis

DeltaE = 2.3RT/nF, 2.3 = ln-log conversion, R = molar gas constant 8.314, n = number of electrons transferred in process
