What to know about lithium cells

What are lithium cells formed from?

One of the fundamental elements of lithium batteries are the cells that make them up and the classic structure of a lithium-ion cell consists of:

  • A cathode, the positive pole of the battery.
  • An anode, the negative pole.
  • A separator, placed between cathode and anode, performs an insulating function avoiding the internal short circuit.
  • An electrolyte containing a lithium salt, which fills the entire cell of the battery, allowing the transport of ions from anode and cathode and vice versa, passing through the separator.
  • Additives, which have the task of facilitating the transport of lithium ions from one electrode to another during the charging and discharging processes of the cell.

There are also different formats of lithium cells as:

  • Pouch cells, literally covered with a protective bag that if worn in any way spoils the operation of the battery.
  • Cylindrical cells, the classic batteries we all have at home.
  • Prismatic cells, the most powerful and voluminous.
