There are many such devices, but the simplest one is a battery. In a battery, a chemical reaction involving the electrolyte (battery fluid) carries ions (charged particles) from one terminal to the other. This flow of charge produces an electric current.
For example, in a lead-acid battery (e.g., a car battery) on the anode (+), lead sulfate reacts with water to form sulfuric acid and lead oxide, while liberating two electrons. These electrons travel through the electric circuit. On the cathode (-), the lead sulfate absorbs the electrons and creates elemental lead and sulfuric acid.

no, its chemical energy to electrical energy.
electrical, chemical, heat, and light energy
In a battery, the energy transformation is: chemical energy -----> electrical energy.
A battery
A battery or a fuel cell converts chemical energy directly to electrical energy
A machine that converts one form of energy into another form is called a transducer.
A storage battery converts chemical energy to electrical energy. Rechargeable batteries can reverse the reaction by converting electrical energy back to chemical energy.
