18500 Cylindrical Battery 3.7V 2000mAh Rechargeable Lithium Ion Battery for Flashlight
Ternary lithium battery, as a variant of lithium battery, is characterized by its positive electrode constructed of ternary material, which is a combination of three elements: nickel, cobalt and manganese. In some cases, anodes may also be made from nickel, cobalt, and aluminum.
This type of battery is popular for its excellent performance, especially in the field of pure electric vehicles. Ternary lithium batteries are not only lightweight, but more importantly, they have high energy density, which means that they can store more electrical energy under the same weight. This feature is crucial to improving the cruising range of electric vehicles. During the charging and discharging process, lithium ions inside the ternary lithium battery will migrate in an orderly manner between the positive and negative electrodes, forming an electric current.
