In this article, we will delve deep into the architecture, benefits, applications, and future prospects of the 18650 ternary lithium battery.
Before discussing the benefits of ternary lithium batteries, it is essential to understand the designation "18650." The term refers to the battery's dimensions: 18mm in diameter and 65mm in length. This cylindrical format offers a high energy density, making it suitable for various portable applications. The 18650 battery is widely adopted due to its ability to deliver a substantial amount of current while maintaining a compact footprint.
Ternary lithium batteries utilize a cathode made from a combination of three different metal oxides, typically nickel, cobalt, and manganese (NCM) or nickel, cobalt, and aluminum (NCA). This triple composition allows for enhanced capacity, safety, and longevity of the battery compared to conventional lithium-ion batteries.
The distinctive chemistry not only boosts energy density but also improves thermal stability and cycle life. The addition of nickel enhances overall capacity, while cobalt contributes to the battery's stability and longevity, and manganese aids in structural integrity and cost efficiency. This balance makes ternary lithium batteries an attractive option for manufacturers aiming to optimize performance while controlling costs.
