  • Introduction: The electrolyte solution is a major component of all battery systems and as such will greatly influence energy densities (thermodynamic properties such as Gibbs energy, enthalpy, and ionic activity) and power densities (nonthermodynamic properties such as viscosity, conductivity, and transference). The electrolyte solution consists of a liquid or solid phase containing at least one component, e.g., water, which is called the solvent, and an ionizable substance, e.g., a salt or an acid, which is called the electrolyte. ...

  • Thermodynamics is one of the most exciting branches of physical chemistry which has greatly contributed to the modern science. Since its inception, great minds have built their theories of thermodynamics. One should name those of Sadi Carnot, Clapeyron Claussius, Maxwell, Boltzman, Bernoulli, Leibniz etc. Josiah Willard Gibbs had perhaps the greatest scientific influence on the development of thermodynamics. His attention was for some time focused on the study of the Watt steam engine.

  • With a reduction of their size, nanoparticles reveal unique properties. A size reduction results in a substantial increase in the specific surface and the surface Gibbs free energy. This physical parameter of free energy reflects the fact that chemical reactivity increases rapidly as particle size diminishes. For example, water has a specific surface of 12.57x10-3 m2 /g at a diameter of one millimetre but the surface expands to 12.57x10+3 m2 /g at a diameter of one nanometre.
