Multiphysics modeling of lithium-ion, lead-acid, and vanadium

Lead-acid batteries may be classified as either flooded or valve-regulated lead-acid (VRLA) depending on the state of the electrolyte. In a flooded lead-acid battery, the electrolyte exists in a reservoir as a free liquid. Accidental contact between electrodes is prevented by coating the negative electrode with a thin separator [195].
