There are several kinds of lithium batteries for new energy vehicles

New energy vehicles have several lithium battery new energy sources that have been cleverly integrated into all aspects of our lives. Electric vehicles are currently widely used. Electric vehicle batteries are inseparable. The battery is commonly known as the battery to ensure the power supply of all electrical systems. The vehicle becomes more and more powerful. The electronic and computer batteries are heavily dependent, and the battery is bad. In the absence of electric vehicles, various failures can occur, and serious ones can lead to paralysis. The author said that there are the following types of lithium batteries for new energy vehicles. Lead-acid battery As a relatively mature technology, lead-acid battery is still the only battery that can be processed in batches for electric vehicles due to its low cost and high discharge rate. To welcome the Beijing Olympics, 20 electric vehicles powered by lead-acid batteries provided transportation services. However, the specific energy, specific power and energy density of lead-acid batteries are very low, so electric vehicles driven by lead-acid batteries cannot have good speed and mileage. New energy vehicle battery type: ternary lithium battery It refers to the positive electrode material of lithium nickel cobalt manganese ternary cathode material lithium battery. It is safer than lithium cobalt oxide batteries, but the voltage is too low. The energy density is between lithium iron phosphate batteries and lithium cobalt oxide 18650 batteries. The future development trend of new energy vehicle batteries is suitable for northern weather, and the batteries are more stable at low temperatures. Representative models: BAIC New Energy EV200, BAIC New Energy EU260, Tesla Model3. The ternary polymer lithium battery is the correct material. The lithium battery using lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary cathode material, the precursor product of the ternary composite cathode material, is cobalt salt, nickel salt, and manganese salt. The raw material, the ratio of nickel, cobalt and manganese can be adjusted according to the actual situation. The active battery ternary material and lithium cobalt oxide battery are safe, but the voltage is too low, and the capacity will be obvious when using mobile phones (mobile phones are generally around 3.0V voltage) insufficient. Nickel-cadmium batteries and nickel-metal hydride batteries have better performance than lead-acid batteries, but they contain heavy metals, which will pollute the environment after being discarded. Ni-MH power lithium-ion batteries have just entered the mature stage. It is the only battery system in hybrid electric vehicles that has undergone large-scale verification and commercialization. At present, Ni-MH power lithium-ion batteries have a 99% market share, and the representative of commercialization is Toyota Prius. At present, the world's important automotive power lithium-ion battery manufacturers include Japan's PEVE and Sanyo. PEVE occupies 85% of the global market share of mixed nickel metal hydride batteries. At present, important commercial hybrid vehicles, such as Toyota's Prius, Alphard and Estima, and Honda's Civic and Insight, all use PEVE's nickel metal hydride battery packs. In our country, Changan jiexun, Chery A5, FAW Pentium, GM Grand Hyatt and other brands of cars are performing demonstrations. They also use nickel-metal hydride batteries, but the batteries are mainly purchased from abroad. The use of nickel-metal hydride batteries in cars in China is still being studied. Matching stage with development. How many types of lithium batteries are there for new energy vehicles? Now that the technology of new energy vehicles is mature, consumers will not worry too much about the type of battery when buying, and now the after-sales service of batteries is more comprehensive, consumers should focus on In the maintenance of cars and batteries.
