How a lithium-ion battery works

This illustration shows the inner workings of a lithium-ion battery.

 

When delivering energy to a device, the lithium ion moves from the anode to the cathode. The ion moves in reverse when recharging.

 

Compared to other rechargeable batteries, lithium-ion batteries can store more energy in smaller, lighter packages. This unsurpassed energy-to-weight ratio make them the battery of choice for consumer electronics like cell phones and laptops, but also a great fit for electrified vehicles.
