Performance comparison of several commonly used batteries

The 18650 battery is a standard lithium battery type set by Sony in order to save costs. Wherein 18 means that the diameter is 18mm, 65 means that the length is 65mm, and 0 means cylindrical battery. Only the type of battery can be divided into lithium iron phosphate battery, lithium cobalt acid battery, and lithium ternary lithium battery according to different cathode information. That year, the Tesla sports car used 18650 lithium cobalt oxide batteries, and later the S model was changed to a ternary data battery customized by Panasonic, that is, a nickel cobalt aluminum ternary positive data battery. The number of batteries used in model-s is 8000+, which is more than 1000 more than Roadster, but the cost is reduced by 30%. What is lithium cobalt oxide and what is ternary lithium battery? You must make it clear! Hey, don’t worry, you can look down, beautiful friend 2. Lithium cobalt oxide battery Lithium cobalt oxide battery is a kind of lithium battery, Its structure is stable, the capacity ratio is high, and the sensing function is outstanding, but its safety is poor and the cost is very high. It is mainly used for processing portable electronic devices such as mobile phones and notebook computers. Tesla is the only company that uses 18650 lithium cobalt ion batteries for its first electric car, Roadster. 3. Ternary lithium battery Ternary lithium battery is a lithium battery made from the ternary positive electrode data of lithium nickel cobalt manganese (Li(NiCoMn)O2). It is related to lithium cobalt acid battery and has high safety and is suitable for power lithium ion. Battery or small battery. Compared with the lithium iron phosphate battery, the energy density of the ternary lithium battery is much higher, about 200Wh/kg, which means that the ternary lithium battery of the same composition has a longer battery life than the lithium iron phosphate battery. The world's five major battery brands, including Sanyo, Panasonic, Sony, LG, and Samsung, have successively introduced ternary data batteries, and low-power and high-power batteries at home and abroad use the most positive ternary data. Representative models: Tesla Model S, BAIC Saab EV, EV200, BMW i3, JAC and Yue iEV5, Chery eQ4. Lithium iron phosphate battery Lithium iron phosphate battery refers to the lithium battery with lithium iron phosphate as the positive electrode data, which is the most prominent Its characteristic is thermal stability, which is the first among automobile lithium batteries, therefore, it has become one of the important categories of electric vehicle batteries. Representative model: BYD E6 hydrogen fuel power battery hydrogen fuel power battery uses the chemical element hydrogen to make a battery that stores energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the cathode and anode respectively. Hydrogen diffuses outward through the attack reaction of the cathode and electrolyte, and electrons are released to the anode through the external load, and only water and heat appear. The power generation efficiency of fuel power cells can reach more than 50%, which is determined by the conversion properties of fuel power cells. Fuel power cells directly convert chemical energy into electrical energy without the need for concentrated conversion of heat and mechanical energy (generators). Now, Toyota's first large-scale processed hydrogen fuel-powered battery car Mirai will be launched in Japan on December 15th. It is expected to be priced at 723,000 yen (about 380,000 yuan) and has a power of 114 kilowatts. The mileage is approximately 650 kilometers. Other representative models: Honda FCV concept car, running b-class fuel-powered car. Statement: Some pictures and content of articles published on this site are from the Internet.
