Introduction
Batteries are everywhere in modern societies. They provide the electric current to 
start our automobiles and to power a host of products such as pocket calculator, 
digital watches, heart pacemaker, radio, and tape recorders.
Electrochemistry is the area of chemistry concerned with the interconversion of 
chemical and electrical. A battery is a an electrochemical cell, a device for 
interconverting chemical and electrical energy. A battery takes the energy released by 
a spontaneous chemical reaction and uses it to produce electricity.

Electrochemical cell:
It is device for converting chemical energy into electrical energy.
Electro chemical cell are of two types
(1) Galvanic cell or Voltanic cell -
• A Spontaneous chemical reaction Generates an electric current
(2) Electrolytic cell -
• An electric current drives a Nonspontaneous reaction

• An electric current drives a Nonspontaneous reaction
Construction of cell (Continued)
• It has two half-cells, each having a beaker containing a metal strip that dips in its 
aqueous solution. 
• The metal strips are called electrodes and are connected by an conducting wire.
• Two solutions are connected by a salt bridge.
• The oxidation and reduction half reactions occur at a separate electrodes and 
electric current flows through the wire.
