The 18650 ternary lithium battery is a type of rechargeable lithium-ion battery that is characterized by its cylindrical shape and dimensions of 18mm in diameter and 65mm in length. The "ternary" designation refers to the battery's incorporation of a ternary cathode material, which typically consists of a combination of nickel, cobalt, and manganese.
One of the defining features of the 18650 ternary lithium battery is its high energy density, which allows it to store a significant amount of energy relative to its size and weight. This makes it an ideal choice for applications where space and weight considerations are paramount, such as in electric vehicles and portable electronic devices.
The 18650 ternary lithium battery comprises several key components, each playing a crucial role in its overall performance and functionality.
The cathode of the 18650 ternary lithium battery consists of a ternary material, typically in the form of lithium nickel manganese cobalt oxide (NMC) or lithium nickel cobalt aluminum oxide (NCA). These cathode materials offer a balanced combination of energy density, power capability, and thermal stability, making them well-suited for a wide range of applications.
At the core of the battery is the anode, which is commonly composed of graphite. Graphite anodes exhibit excellent cycling stability and low irreversible capacity, contributing to the overall longevity and reliability of the battery.
The electrolyte serves as the medium for ionic conduction between the cathode and anode. In ternary lithium batteries, the electrolyte typically consists of a lithium salt dissolved in a mixture of organic solvents. This electrolyte formulation facilitates efficient ion transport and ensures the overall electrochemical integrity of the battery.
Separating the cathode and anode is a porous separator, which prevents electrical short circuits while allowing the passage of lithium ions. The separator is typically made of a microporous polymer membrane with high permeability and mechanical strength.
The entire assembly is enclosed within a cylindrical casing, typically made of steel or aluminum, which provides structural support and electrical insulation for the battery.
