Detailed interpretation of lithium battery pack.18650 3.7v battery

　　1. Classified by appearance

　　Cylindrical lithium battery: The type of name is generally 5 digits, the first two digits are the diameter of the battery, the two -digit number between the battery is the height of the battery, and the unit is millimeter.

　　Very common cylindrical lithium batteries: 18650, 21700, 26650, 32650, etc.

　　Square lithium batteries usually refer to aluminum shells or steel shell square lithium batteries, which are widely used in exploration and drawing, medical equipment, etc.

　　Press the shell classification

　　Steel shell lithium battery: Because the steel shell is heavy and the security is poor, but the stability of the steel is strong. In the later period, many manufacturers have optimized the planning structure through the security valve, PTC and other equipment, which greatly increases its security performance. Some of them directly replace the steel shell, using aluminum shells and soft bags, such as lithium battery packs in the current mobile phone.

　　Third, according to positive data classification

　　There are four types of lithium -ion batteries: there are four types of information: lithium cobaltate batteries, lithium manganate batteries, lithium iron phosphate batteries, and nickel cobalt manganese (ternary) lithium batteries.

　　4. Classification of its application category

　　1. Consumer product category

　　The first is used in digital products, mobile phones, mobile power and other electronic devices. Commonly used is 18650 battery, lithium polymer battery.

　　2. Industrial category

　　The primary application in the fields of medical electronics, photovoltaic energy storage, railway infrastructure, security communication and other categories. Commonly used are energy storage, power lithium batteries, lithium iron phosphate batteries, polymer lithium batteries, etc.

　　3. Special category

　　The primary application is in the fields of aerospace, ships, satellite navigation, and high -energy physics. Commonly used are ultra -low -temperature lithium batteries, high -temperature lithium batteries, lithium titanate batteries, explosion -proof lithium batteries, etc.
