With the global shift towards renewable energy and sustainable electrification, understanding the characteristics and advancements of this particular battery type is crucial. This article will delve into the anatomy of 18650 ternary lithium batteries, their advantages, applications, and the latest trends in research and manufacturing.
The term 18650 refers to the specific dimensions of the cylindrical lithium-ion battery: 18mm in diameter and 65mm in length. Ternary lithium batteries, known for their use of three types of metal oxides—nickel, cobalt, and manganese—are a popular choice for various applications ranging from portable electronics to electric vehicles and energy storage systems.
The core of an 18650 ternary lithium battery consists of a positive electrode made primarily of lithium nickel cobalt manganese oxide (NCM) or lithium nickel cobalt aluminum oxide (NCA). The combination of these metals provides a synergistic effect that enhances energy density and stability.
The negative electrode, typically composed of graphite, acts as a host for lithium ions. During the charging process, lithium ions transfer from the positive to the negative electrode. Upon discharging, the reverse occurs. This fundamental electrochemical reaction is responsible for the battery's ability to store and release energy efficiently.
