What is the classification of lithium-ion batteries?

Important classification of lithium ion batteries There are many types of lithium ion batteries. According to the different cathode materials, they can be divided into lithium ferrite batteries, lithium cobalt oxide batteries, lithium manganate batteries, lithium nickel oxide batteries, and ternary materials lithium ion batteries. , Iron phosphate lithium ion batteries, etc.; according to different electrolyte materials, it can be divided into liquid lithium ion batteries and solid polymer lithium ion batteries; from the packaging point of view, it can be divided into soft packaging, steel shell packaging, aluminum shell packaging, etc.; from the point of use Said, it can be divided into power-type lithium-ion batteries, consumer-type lithium-ion batteries, energy-storage-type lithium-ion batteries and so on. From the shape of lithium-ion batteries: 1. Cylindrical Li-ion Battery (CylindricalLi-ionBattery) The cylindrical appearance and internal structure are shown in the figure. Usually the positive and negative electrodes and the separator are wound on the negative pole and then loaded Cylindrical steel shell, then inject electrolyte, seal, and finally the product can be shaped. The following figure also includes safety components such as positive temperature coefficient terminals (PTC) and safety valves (SafetyVent). 2. Prismatic Li-ion Battery (PrismaticLi-ionBattery) The appearance and internal structure of the Prismatic Li-ion battery are shown in the figure. Its important parts are similar to cylindrical lithium-ion batteries, and the main components are the positive and negative electrodes, electrolyte, and shell composition. Generally, when the electrolyte is liquid, a steel shell is used; if a polymer electrolyte is used, aluminum-plastic packaging materials can be used. 3. CoinLi-ionBattery (CoinLi-ionBattery) In addition to cylindrical lithium-ion batteries and square lithium-ion batteries, there are coin Li-ion batteries (CoinLi-ionBattery), which have a simple structure and are usually used for scientific research and testing. 4. ThinFilmLi-ion Battery (ThinFilmLi-ionBattery) ThinFilmLi-ionBattery is the latest field in the development of lithium-ion batteries. Its thickness can reach millimeters or even micrometers. It is often used in bank anti-theft tracking systems, electronic anti-theft protection, miniature gas sensors, and miniature coulombs. Microelectronic equipment such as design.
