Battery

Introduction

• What is a battery? A device that stores chemical energy and converts it into electrical energy.

• Types of batteries: Primary batteries (non-rechargeable) and secondary batteries (rechargeable).

Primary Batteries

• How primary batteries work: Chemical reactions within the battery produce a voltage difference, creating an electric current.

• Common primary batteries: Alkaline batteries, carbon-zinc batteries, lithium batteries.

• Advantages and disadvantages of primary batteries.

Secondary Batteries

• How secondary batteries work: Rechargeable batteries can be recharged by reversing the chemical reactions that occur during discharge.

• Common secondary batteries: Lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries.

• Advantages and disadvantages of secondary batteries.

Battery Components

• Electrodes: Positive and negative terminals of a battery.

• Electrolyte: A substance that conducts electricity and facilitates the chemical reactions in the battery.

• Separator: A porous barrier that separates the electrodes and prevents them from coming into direct contact.

Battery Capacity and Voltage

• Battery capacity: The amount of electrical energy a battery can store.

• Battery voltage: The potential difference between the battery's terminals.

• Factors affecting battery capacity and voltage: Battery size, chemistry, and age.

Battery Safety

• Proper handling and storage: Tips for safe use and storage of batteries.

• Recycling batteries: The importance of recycling batteries to protect the environment.
