1 Introduction. Entropy is a thermodynamic parameter which represents the degree of randomness, uncertainty or disorder in a material. 1, 2 The role entropy plays in the phase stability of compounds can be understood in terms of the Gibbs free energy of mixing (ΔG mix), ΔG mix =ΔH mix −TΔS mix, where ΔH mix is the mixing enthalpy, ΔS

Electrochemical energy storage. Electrochemical energy storage is a method used to store electricity in a chemical form. This storage technique benefits from the fact that both electrical and chemical energy share the same carrier, the electron. This common point allows limiting the losses due to the conversion from one form to another.
