Batteries are made of two electrodes involving different redox couples that are separated by an electronically insulating ion conducting medium, the electrolyte. The later might be a solid (inorganic or polymer ), despite conductivities being typically very low at room temperature (<0.1 mS/cm) or most commonly a liquid with a certain concentration of dissolved salt.
Having powerful and robust solutions for analysis in battery and energy materials is of the utmost importance, especially in light of the increase in the production of electric vehicles …
