Lithium-ion battery pack is extremely popular and versatile nowadays. Applied in wireless communication, power tools, consumer electronics and other types of electronic devices, the lithium-ion battery packs have been influencing our daily life. It is the advanced technologies that make them a great choice for power supply. But how does a lithium-ion battery work and what makes it so distinctive among others? We will introduce the critical components that make up a lithium-ion battery pack and why lithium-ion batteries have high energy density and long battery life.

What is Lithium-ion Battery and How Do Lithium-ion Batteries Work

Lithium-ion batteries come in different types and sizes, but their construction is typically the same. To understand how lithium-ion batteries work, it is essential to understand the role of individual parts of a lithium-ion battery.

What are the Parts of a Lithium-ion Battery Pack?

How is a lithium-ion battery pack constructed? A lithium-ion battery pack is a set of identical batteries or individual battery cells configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. And the three primary functional components of a lithium-ion battery are the positive and negative electrodes and electrolyte.

Just like the alkaline dry batteries used for electronic devices’ remote control, lithium-ion battery generate power through the movement of ions. Since the lithium element is extremely reactive in its elemental form, a lithium-ion battery usually contains a lithium-metal oxide, such as lithium-cobalt oxide instead.

How does a lithium-ion battery pack work? It houses a bank of cells together with the associated interconnections in a single convenient pack, which enables higher voltage or higher capacity to be built up from low voltage, low capacity cells. The lithium-ion battery pack is usually spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection to ensure safe operation.

How Do Lithium-ion Batteries Work

Generally, all lithium-ion batteries work in the same way. During discharge of the li-ion battery, the negative electrode (anode) releases electrons that travel along the wire and are absorbed by the positive electrode (cathode). This flow of electrons is electric current, which can then be converted to power for electric motors or electronic devices.

As mentioned above, lithium-ion batteries and alkaline batteries share the same basic components, but there are some differences. The overall design of a lithium-ion battery provides many benefits for equipment users. Generally speaking, the lithium-ion battery pack is more reliable and stable than the traditional battery as it doesn’t suffer from the memory effect problem. Since lithium-ion battery pack doesn’t contain cadmium (a toxic heavy metal),it appears to be more environmentally friendly. These advantages have made lithium-ion batteries distinctive among others.

So far, the lightweight lithium-ion battery packs are used in a wide range of cutting-edge electronic devices such as wireless stereo headsets, electronic cigarettes, walkie-talkies and some smart home appliances.
