The First Battery
Batteries transform chemical energy into electrical energy.
Alessondro Volta
Argued that the electrical effect Galvani observed was actually a result of a chemical reaction, he thought that this happened between the two metals, and the salty fluids in the frogs leg muscle.
He built the first electric battery by layering zinc, paper soaked in salt water, and silver.
Luigi Galvani
The reaserch that made the battery came by accident
He was studying the anatomy of a frog. when something happened that made the frogs leg twitch. Galvani thought that there was some sort of animal electricity.
Electrochemical Cells
In Volta's setup, each pair of zinc and silver layers separated by paper soaked in salt water acted as an electrochemical cell. An electrochemical cell is a device that converts chemical energy into electrical energy.
A Simple Cell
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell. These reactions cause one electrode to become negatively charged and the other electrode to become positively charged.
Consist of two different metals called electrodes, which are immersed in a substance called an electrolyte. An electrolyte is a substance that conducts electric current.
Batteries
Several electrochemical cells can be stacked together to form a battery, which is a combination of 2 or more electrochemical cells in a series
Wet Cells
An electrochemical cell in which the electrolyte is a liquid is a wet cell
Dry Cells
An electrochemical cell in which the electrolyte is a paste is a dry cell
