Conductivity: The presence of electrolytes increases the conductivity of the solution. Higher conductivity means more efficient ion transport and better voltage production. A solution with optimal electrolyte concentration has improved performance, as demonstrated in a study published in the Journal of Power Sources (Xie et al., 2015).
-
Energy storage: In batteries, electrolytes help in energy storage by maintaining the balance of charge. For example, during discharge, two different reactions occur: oxidation at the anode and reduction at the cathode. The electrolyte ensures that the resulting ions can move between the electrodes, facilitating continuous voltage production.
-
Biological systems: In living organisms, electrolytes such as sodium, potassium, and calcium ions are critical for generating electrical impulses in nerve and muscle cells. This is essential for functions like heartbeat regulation and muscle contraction, as highlighted in a review by Kandler (2012) in “Neuron”.
Due to these functionalities, a lack of electrolytes can hinder voltage production and electrical activity both in devices and biological systems, illustrating their importance in maintaining energy transfer and function.
