Battery Chemistry Basics

Electrochemical Reaction

Batteries store and deliver power through electrochemical reactions. These reactions involve the movement of electrons from one material to another. This movement generates electrical energy.

The battery consists of two main parts: the anode and the cathode. The electrolyte is a substance that allows ions to move between these two parts. In many batteries, this electrolyte is a liquid electrolyte.

Cathode and Anode Roles

During battery discharge, the anode and cathode play distinct roles. The anode releases electrons into the external circuit. These electrons travel through the circuit to power devices.

The cathode receives these electrons from the circuit. Inside the battery, cations move through the electrolyte towards the cathode. This process balances out the charge.

Redox Reactions

Redox reactions are central to converting chemical energy into electrical energy in batteries. "Redox" stands for reduction-oxidation reactions.

Oxidation occurs at the anode where it loses electrons.
Reduction happens at the cathode where it gains electrons.

These reactions ensure continuous electron flow through the circuit, generating electricity.

Circuit Voltage

Circuit voltage refers to the electric potential difference between two points in a circuit. In a battery, this is often called terminal voltage.

Terminal voltage depends on several factors:

Type of materials used for anode and cathode
Concentration of electrolytes
Temperature conditions

Higher terminal voltage means more power can be delivered by the battery.

Liquid Electrolyte Advantages

Liquid electrolytes have some advantages over solid ones:

They allow faster ion movement.
They make batteries more efficient.
They enable higher power output.

However, they may also pose leakage risks if not properly sealed.
