Li-ion batteries for instance ones that have the lithium cobalt oxide cathode could provide a little more capacity. But, they're also more reactive due to the less thermal capabilities. Another option that is highly recommended is iron lithium phosphate. The life span of their products is about four times longer. 

Lithium-ion or Li-ion battery is among the many kinds that rechargeable batteries are available. In the process of discharge, the lithium ions move from the anode towards the cathode and back again. Learn more about the benefits of lithium-ion batteries.

How do these batteries function?

Different types of lithium-ion batteries use various cathodes. The cathodes are composed of lithium molecules. 

In general, the anodes are composed of carbon. Similar to other types of batteries the chemical reactions that take place between the cathode and anode and electrolyte create electricity. 

Here are the advantages of lithium-ion batteries:

Smaller and lighter:

They're light but have more capacity than other batteries available. So, they are typically utilized in portable devices with physical specifications such as size and shape are crucial factors.

Energy Density

Lion batteries are denser in terms of energy than other kinds which means you will have more capacity, regardless of size. 

This is the reason why they are the best option for devices that consume a lot of power like laptops and smartphones. As technology advances, we'll see higher capacity batteries in the future.
