Lead Storage Battery & Daniell Cell

 Lead Storage Battery

A battery is a group of cells which are connected together. It is reversible cell which can be restored to its original condition lead storage battery is used in automobiles. A 12v storage battery consists of six voltaic cells connected together in series. Each cell providing about 2v. In lead storage battery anodes are the lead alloy and cathodes are made up of red lead dioxide. The electrolyte is dilute sulphuric acid. Example: car battery.

Daniell Cell

A Daniell cell is the simplest of the galvanic or voltaic cells which is used to convert chemical energy into electrical energy quickly. Daniell cell consist of two half cells. One half cell is zinc rod dipped in zinc sulphate (ZnSO4) solution and other half cell is copper road dipped in copper sulphate (CuSO4) solution. The two half cells separated from each other by salt bridge.
