Electronics - Design And Function - 1 Of 4: Battery: Terminology: Electrolyte

In a lead battery, electrolyte consists of concentrated sulfuric acid and distilled water. Electrolyte is a liquid that conducts current and adds hydrogen and sulfate ions to the electro-chemical reaction during charging and discharging:

PbO₂ + Pb + 2 H₂ SO₄ = 2 PbSO₄ + 2 H₂ O
