Lithium battery is a rechargeable battery commonly used in electronic equipment, electric vehicles, energy storage systems and other fields.

Lithium batteries have become the preferred power source widely used in various industries due to their high energy density, long life, lightweight and portability.

This article will introduce the working principle, advantages and application fields of lithium batteries.

How do lithium batteries work?

The core of a lithium battery is a battery unit composed of a positive electrode, a negative electrode and a separator.

1. While charging

During charging, current flows from the external power source into the interior of the lithium battery, causing lithium ions to flow from the positive electrode material to the negative electrode material and transfer between the separators.

2. During discharge

The opposite is true during discharge. Therefore, the cyclic movement of lithium ions can realize the storage and release of electrical energy.

Advantages of lithium batteries:

1. Higher energy density and longer life

Compared with traditional lead-acid batteries and nickel-metal hydride batteries, lithium batteries have higher energy density and longer life.

2.Short charging time

3. Light weight

4. No memory effect

5. Environmentally friendly

What are the applications of lithium batteries?

1. Electronic equipment field

Lithium batteries are widely used in consumer electronics such as various mobile phones, tablets, and laptops.

2. Electric vehicle field

The high energy density and long life of lithium batteries make them the main power source for electric vehicles and hybrid vehicles.

3. Energy storage system

Lithium batteries are also used in energy storage systems such as solar panels and wind turbines.

In short

Lithium batteries are widely used in various industries due to their high energy density, long life and environmental protection.
