Electrolyte density refers to the concentration or mass of electrolytes present in a battery''s solution. It measures the amount of electrolyte dissolved in a given solvent volume, typically expressed in grams per milliliter (g/mL) or cubic centimeters (g/cm³). The electrolyte in a battery is typically a solution consisting of a solvent (such as water) and various dissolved substances
Mass is a measure of how much matter there is within an object or liquid while density expresses how much mass there is per a certain amount of volume. For example, 10 kg of steel and 10 kg of feathers have the same mass, but different volumes therefore they have different densities.
Porosity is frequently specified as only a value to describe the microstructure of a battery electrode.
