Lithium Metal vs Lithium-ion Battery


You must be familiar with batteries as they are frequently used in our daily life. There are many kinds of batteries, such as lead-acid batteries, nickel-cadmium batteries, lithium-ion batteries, and so on. Do you know the characteristics of each battery?

In this article, let’s take a closer look at these two popular batteries — lithium metal battery and lithium-ion battery.

Part 1. What Are The Differences Between Lithium Metal Batteries And Lithium-Ion Batteries?

1. Cell Type

The most significant difference between lithium metal batteries and lithium-ion batteries is their cell type. Lithium metal batteries are primary cell construction, which means that they cannot be recharged. On the other hand, lithium-ion batteries are secondary cell construction, which means that they are chargeable and can be used repeatedly.

2. Material 

Lithium metal batteries use lithium metal as the negative electrode material. Due to the active chemical properties of lithium metal, the processing, storage, and use of these batteries have very high environmental requirements.

The negative electrode material of lithium-ion batteries is graphite. It has higher security.

Part 2. What Are The Advantages of A Lithium-Ion Battery Over A Lithium Metal Battery?

Lithium-ion batteries are gaining more and more popularity in our daily life. What advantages do they have in comparison with lithium metal batteries?

Firstly, lithium-ion batteries are safe to use. Lithium metals are unstable, especially during charging. Although the energy density of lithium ion is slightly lower than lithium metal, it is safe as long as certain precautions are observed while charging and discharging.

Secondly, lithium-ion batteries are chargeable while lithium metal batteries can’t be charged. As a result, items that require charging need lithium-ion batteries. With the use of lithium-ion batteries, people can charge their mobile phones, laptops, and other devices conveniently.


I believe that by reading this article, you will have a general understanding of lithium metal batteries and lithium-ion batteries. They are all widely used today and facilitate our lives. And they all have advantages and limitations. You can choose the right battery according to your needs.
