  Cylindrical batteries   can be categorized based on their filler materials into several types: lithium iron phosphate batteries, lithium cobalt oxide batteries, lithium manganese oxide batteries, and cobalt-manganese hybrid batteries. Additionally,  cylindrical lithium batteries  are differentiated by their shell types, which include steel shell lithium batteries and polymer shell lithium batteries.   Part 1: Characteristics of Cylindrical Batteries 1. Appearance of Cylindrical Lithium Batteries Cylindrical lithium batteries typically consist of a positive electrode material (such as nickel-cobalt oxide or zinc-manganese oxide), separator paper, and an electrolyte. The battery casing is usually made from an aluminum-plastic composite pipe.   2. Capacity of Cylindrical Lithium Batteries The rated energy density of a single cylindrical lithium battery ranges from 300 to 500 Wh/kg, with a specific power exceeding 100 W. The actual performance can vary depending on the model and specific

 In the realm of  lithium-ion batteries , the 26650 and 18650 models have gained significant popularity. While they share some common features, their differences are key to understanding their unique advantages. This article explores the distinctions between these two battery types in detail.   Before delving into their specific characteristics, it's essential to grasp the basics of lithium-ion batteries. The names 26650 and 18650 are derived from their physical dimensions:   -  26650 Battery ​: 26mm in diameter and 65mm in length - 18650 Battery: 18mm in diameter and 65mm in length   Though these size differences may seem minor, they significantly influence each battery's performance and utility.   26650 Battery: An Overview   The  26650 lithium-ion battery , being larger than the 18650 model, offers a higher energy capacity. This increased size enables it to achieve a greater ampere-hour (Ah) rating, reflecting its ability to store more energy.   Thanks to its superior capaci
