The term "18650" describes the dimensions of the cylindrical battery: 18mm in diameter and 65mm in height. Ternary lithium batteries specifically refer to those that utilize a cathode made from a mixture of nickel, cobalt, and manganese, collectively known as NCM or NCA depending on the composition of these elements. The unique combination of materials results in a battery that has a higher energy density compared to conventional lithium-ion batteries, leading to prolonged usage times.
The chemistry of 18650 ternary lithium batteries is primarily based on the movement of lithium ions between the anode and cathode during charge and discharge cycles. The anode is typically made of graphite, while the cathode is composed of lithium metal oxide (the ternary composition of nickel, cobalt, and manganese). During discharging, lithium ions flow from the anode to the cathode, generating electrical energy that can be harnessed to power various devices.
The ternary composition enriches the battery's performance, where each element serves a specific purpose:
