lead accumulator short note chemistry
Answers
Lead accumulator. The most common type of heavy duty rechargeable cell is the familiar lead-acid accumulator('car battery') found in most combustion-engined vehicles. A simple lead-acid cell consisting of strips of lead and an electrolyte of dilute sulfuric acid is constructed and charged for different lengths of time.
Answer:
Lead Accumulator
A lead accumulator is a secondary cell because electrical energy is not generated within the cell itself but it is previously stored in it from the external source. The energy is stored in the form of chemical energy. So this cell is a storage cell or accumulator or storage battery.
They generate electricity through a double sulfate chemical reaction. Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate. It impedes recharging; sulfate deposits ultimately expand, cracking the plates and destroying the battery.
To keep lead acid in good condition, apply a fully saturated charge lasting 14 to 16 hours. If the charge cycle does not allow this, give the battery a fully saturated charge once every few weeks. If at all possible, operate at moderate temperature and avoid deep discharges; charge as often as you can.
Lead-acid battery (rechargeable): This is the chemistry used in a typical car battery. The electrodes are usually made of lead dioxide and metallic lead, while the electrolyte is a sulfuric acid solution.
