Take you three minutes to know the lithium battery

Three minutes to know that lithium batteries Lithium batteries are claimed to be the core of today's mobile devices, showing their importance. Lithium battery itself is a generalization, a big concept, lithium battery, lithium battery, lithium ion polymer battery, there are many articles in a few words, and the cost difference is also different. Lithium battery is generally the abbreviation of lithium battery, but strictly speaking, it is very different from lithium battery. Lithium battery is a kind of lithium primary battery, which uses lithium metal or lithium alloy as negative electrode material, contains pure lithium metal, and uses non-aqueous electrolyte solution as a disposable battery. Lithium batteries are disposable batteries, that is, lithium batteries mean that lithium batteries can be charged and discharged repeatedly? No. Generally speaking, a rechargeable lithium battery consists of a graphite negative electrode, a positive electrode using cobalt, manganese or iron phosphate, and an electrolyte that transports lithium ions. But there are also disposable lithium batteries, which use lithium metal, and perhaps use embedded lithium data as the negative electrode. Read about mobile power: Some things you need to know about lithium batteries. Compared with lithium batteries, there is one more word ion, which emphasizes the transportation of lithium ion electrolyte. The 18650 battery as we know it contains an adsorbed liquid electrolyte, so all 18650 batteries are lithium batteries. The reason for the 18650 battery that is proposed to be independent of the lithium battery is that the lithium ion rechargeable and discharge battery has a diameter of 18 mm and a length of 65.0 mm by Sony according to the processing to be more widely used and universal in industrial specifications. Therefore, in addition to the 18650 specifications, we also have 16340 batteries. The term polymer for lithium-ion polymer batteries emphasizes the fact that the electrolyte is colloidal, solid, or semi-solid. The reason why lithium-ion polymer batteries are so powerful is that solid polymers replace traditional liquid electrolytes. The advantage of using colloidal or solid polymer instead of liquid organic solvent electrolyte is that the polymer can be made into any shape, suitable for different equipment, strong adaptability, and the freedom of industrial design of the equipment is guaranteed. For example, mobile phones (18650, a fixed-shaped battery that uses liquid electrolyte, obviously not suitable for today's smart phones). Second, the electrolyte in the polymer state is safer: the liquid electrolyte will explode under extreme conditions of short circuit, high temperature, and high pressure, while the polymer will only expand and bulge. Under extreme conditions, explosion and incineration will not occur. Through the above simple analysis, what kind of impressions do we have on lithium batteries?
