Analyze new energy vehicle power lithium-ion battery technology

New energy vehicle power lithium ion battery power lithium ion battery as the core component of new energy vehicles, its performance directly affects the car's endurance, speed, charging speed and safety. Most of the power lithium-ion batteries used in cars now come from lithium-ion power lithium-ion batteries. Tracing the origin and development of lithium batteries has been full of difficulties and doubts along the way. In the 1990s, lithium batteries were first commercialized in Japan, from the beginning of the 3C digital field to today’s power lithium-ion batteries; from early lead-acid batteries, nickel-hydrogen batteries, nickel-cadmium batteries, to today’s lithium batteries; from phosphoric acid Lithium iron battery, to ternary battery, future lithium metal, lithium sulfur battery, lithium air battery. With the hard work of generations of scientists and engineers, we have been working hard to change our lives through science and technology and supply green and clean energy. As I said, electric vehicles, especially pure electric vehicles, are driven by batteries and electric motors. When we discuss batteries here, you can think of them as battery packs, which are made up of hundreds of single cells. Commonly used lithium batteries can be divided into lithium cobalt oxide, lithium manganate, lithium iron phosphate, and lithium ternary lithium batteries. According to the different anode materials used, they can be divided into cylindrical batteries, square batteries, and soft batteries according to their shapes. There are related analysis in my early articles, and friends who are interested can check it out. The manufacturing process of lithium-ion power lithium-ion batteries is more complicated. For details, please refer to my previous article, from slurry to volume. The whole can be divided into five parts: positive electrode, negative electrode, electrolyte, diaphragm, and outer shell. After a series of processing, they are suitable for combination. Make cells one by one. Then put these batteries into the modules in series and parallel, put the modules with different numbers into the battery pack, and assemble them into a BMS, thermal management system, etc. After passing the test, the battery pack can be assembled on the vehicle to supply power to the vehicle.
