The Phylion 48v24ah lithium battery is a ternary battery.
What is “ternary”? Ternary lithium battery refers to the use of lithium-nickel-cobalt manganate or lithium-nickel-cobalt aluminate as the positive electrode material and graphite as the negative electrode material using lithium salts. mainly composed of lithium hexafluorophosphate as the electrolyte.
There are two main ways to name lithium batteries. One is named after the positive element of the battery, and the other is named after the main reaction mechanism and characteristics of the battery (such as flexible and solid batteries). -battery condition). The ternary lithium battery owes its name to the material of its cathode. Since the cathode material contains three metallic elements: nickel, cobalt and manganese/aluminum, it is called "ternary".
It should be noted that lithium titanate batteries are an exception. Although their positive electrodes also contain three metal elements, their negative electrodes are made of lithium titanate instead of ordinary graphite, so they are not ordinary ternary lithium batteries.
Among cathode materials, the main function of nickel is to increase the volumetric energy density of the battery, which is the main breakthrough for increasing cruising range. Cobalt can inhibit the mixing of cations, thereby improving stability and extending battery life. Additionally, it also determines the charge and discharge speed and efficiency (rate performance) of the battery.
The role of manganese or aluminum is to reduce material costs and improve the safety and stability of batteries.
