Battery Cells

The cathode, also known as the positive electrode, consists of a mixed-metal oxide containing lithium. While charging the battery, the lithium-ions move out of the crystal structure of the cathode and travel to the anode. High performance cathode active materials provide a higher energy density, which enables longer driving distance by combining a high degree of purity, unique morphology and excellent electrochemical properties.

The anode, also known as the negative electrode, is made of graphite, a natural form of carbon with a layered structure. While charging the battery, the lithium-ions are incorporated into the anode.

Electrolytes allow the lithium-ions carrying the battery’s charge to flow freely between the cathode and the anode. Electrolytes must be extremely pure and as free of water as possible in order to ensure efficient charging and discharging of the battery.
