Inside a Lithium-
Ion Battery
The negative electrode of a battery. In a lithium-ion battery, this typically consists of a carbon compound, commonly graphite.
The positively or negatively charged materials within a battery. Each electrode is attached to a current collector that transmits the current to the tab or terminal.
A liquid or gel that conducts electricity. The electrolyte allows the continuous movement of Li+ ions during cell operation. In a lithium-ion battery, the electrolyte typically consists of a mixture of organic carbonates and LiPF6 salt.
A porous polymeric (plastic) film that “separates” the electrodes from each other to prevent internal short circuit. At the same time, the separator enables the exchange of lithium-ions from one electrode to the other within the cell.
The positive electrode of a battery. In a lithium-ion battery, this typically consists of a lithium metal oxide like LiCoO2.
The positively or negatively charged materials within a battery. Each electrode is attached to a current collector that transmits the current to the tab or terminal.
The negative electrode
The positive electrode.
A thin porous membrane that separates the anode and cathode. It enables the exchange of electrically charged ions from one side to the other.
