cylindrical li ion battery
The cylindrical li ion battery represents a cornerstone in modern energy storage technology, featuring a distinctive rolled design that maximizes energy density within a compact form factor. These batteries utilize lithium-ion chemistry, incorporating a cathode, anode, separator, and electrolyte housed within a robust metal casing. The most common format, the 18650 cell, measures 18mm in diameter and 65mm in length, though other sizes exist to meet various applications. The internal construction involves layers of electrode materials wound into a tight spiral, creating an efficient power generation and storage system. These batteries typically operate at voltages between 3.6V and 3.7V, delivering reliable power output across a wide range of applications. The cylindrical design inherently provides excellent mechanical stability and effective heat dissipation, contributing to enhanced safety and longevity. These batteries excel in applications requiring high energy density, from electric vehicles to portable electronics. Their standardized dimensions facilitate easy integration into various devices, while their robust construction ensures reliable performance under diverse operating conditions. Modern cylindrical li ion batteries incorporate advanced safety features, including pressure relief mechanisms and thermal protection, making them increasingly popular in both consumer and industrial applications.
