Standard electrode potential
An electrode’s potential under standard conditions, tabulated against the standard hydrogen electrode. Lithium’s −3.04 V is the most negative of any metal, which is why lithium cells have the highest voltages. [1]

Example
Electrochemistry fundamentals: an example situation
A circuit can predict terminal voltage while leaving electrode potentials and reaction kinetics unresolved.
Read Standard electrode potential alongside Cell voltage in this context. The difference between the positive and negative electrode potentials at equilibrium: for NMC against graphite about 3.7 V. It is set by the chemistry, and the difference in Gibbs free energy of the cell reaction per unit charge.
