I can't quite read the question, but a battery is a device that converts chemical energy to electrical energy. Actually young grashopper you ar wrong it is a cell. Hahahahahahaahaa.phew
A dynamo
Typically the nuclear energy is converted to electricity and the electricity powers the device. No much differently than the chemical energy in fossil fuels is often converted to electricity and the electricity powers the device.

A cell aka battery.
synthesis
The wind produces energy by pushing against a fan. The fan operates a power making device ( generator, turbine) to produce the electricity. The amount of wind can make more or less power from the system.
The energy in fuel that produces electricity is chemical energy. By rapidly oxidizing, "burning", the carbon, hydrogen and sulfur in the fuel we produce heat. this heat is absorbed by water to produce steam to drive an engine, this engine turns an electromagnet (field rotor) inside another electromagnet (stator) to generate electricity for use. The transformation of fuel to electricity is as follows: Chemical energy to heat energy to mechanical energy to electrical energy. Only about 25% of the energy in fuel becomes electricity.
Exothermic Reaction
in biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm in electricity, a device that produces an electric current by converting chemical or radiant energy into electrical energy
The energy comes from the chemical activity in the battery producing electricity. Chemical activity produces energy by breaking down chemical bonds. See the link below:
Electricity is Energy. But this energy can come from a chemical reaction as in batteries, normal and rechargeable.
