Thereby, tailoring of open circuit potentials becomes possible. It is evident, that a model which predicts the open circuit potential of arbitrary blends is beneficial to determine the blend ratio prior to manufacturing. Likewise such a model can be potentially applied to determine the composition and blend ratio of unknown cathodes.

Open circuits by design Open circuits are often created by design. For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use. Technically, that's creating an open circuit.
