How Lithium-Ion Batteries Work

lithium-ion batteries work

Lithium-ion batteries are a rapid-response solution for energy storage needs. This particular battery technology is a popular with grid-scale applications. Keep reading for an outline how lithium-ion batteries work.

What are lithium-ion batteries?

Lithium-ion batteries are a battery energy storage technology useful for storing and distributing onsite generated power. They can be found in laptops, cell phones and vehicles as well. Lithium-ion batteries are a sought after technology because of their recharging abilities, light weight and high energy density. Energy density refers to the amount of energy a battery can store with respect to its mass and is measured in watt-hours per kilogram (Wh/kg).

How do lithium-ion batteries work?

Battery’s are made up of one anode, cathode, separator, electrolyte and positive and negative current collectors. Lithium-ion batteries work by moving positively charged lithium ions from anode to cathode and back through the separator. This flow frees electrons which creates a positive charge and these positively charged ions are carried by an electrolyte. The free electrons cause current to flow through what it is powering and then back to the negative current collector. It is the separators job to block electrons from flowing freely inside the battery. In this particular battery technology, lithium is stored in the anode and cathode.
