Anode

The negative electrode of a battery. In a lithium-ion battery, this typically consists of a carbon compound, commonly graphite.

Electrode

The positively or negatively charged end of a battery. Each electrode is attached to a current collector that transmits the current to the device.

Electrolyte

A liquid or gel that conducts electricity.

Separator

A thin porous membrane that separates the anode and cathode. It enables the exchange of electrically charged ions from one side to the other.

Cathode

The positive electrode of a battery. In a lithium-ion battery, this typically consists of a lithium metal oxide like LiCoO2.
