Your position：The 18650 ternary lithium battery is a type of rechargeable lithium-ion battery that has become increasingly popular in various applications, from consumer electronics to electric vehicles (EVs) and energy storage systems. The "18650" designation refers to the battery's dimensions: 18mm in diameter and 65mm in length. This article explores the design, benefits, applications, and future of the 18650 ternary lithium battery.
The 18650 battery is primarily composed of three key components: the anode, cathode, and electrolyte. The "ternary" in its name refers to the mixed metal oxides used in the cathode, typically a blend of nickel, cobalt, and manganese (NCM) or nickel, cobalt, and aluminum (NCA). This combination allows for a higher energy density, which is crucial for applications that require lightweight and compact power sources.
The anode of most lithium-ion batteries, including the 18650, is typically made from graphite. When it comes to the electrolyte, lithium salts in organic solvents are used to facilitate the movement of lithium ions between the anode and cathode during charge and discharge cycles.
The 18650 ternary lithium battery offers several advantages:
