Lithium batteries
Li-Ion or Lithium batteries are one of the most common batteries used today.
We can find this type of battery in mobile phones, wireless headphones, UPS, smartwatches, cars, etc.
Lithium is a very light metal capable of generating ions easily, making it ideal for the manufacture of batteries.
Unlike other types of batteries, they are a bit more expensive, but in return, they are much smaller and lighter, capable of doubling the duration of a Ni-Cd battery.
Thanks to their composition, they can be manufactured in different shapes, adapting to the device where they are to be located, and their low memory effect makes them ideal for any type of device.
Summarizing their positive points:
