What are the types of batteries for new energy vehicles, and which is the best in comparison?

There are many types of new energy vehicle batteries, but they are generally divided into two categories. One type is energy storage batteries, and the lithium batteries we often say fall into this category. One type is fuel power battery, which is used by Toyota Mirai. There are many types of energy storage batteries, such as lithium batteries, lead-acid batteries, sodium-sulfur batteries and so on. Lithium batteries are the most widely used. Among them, lithium batteries are divided into ternary lithium batteries, lithium iron phosphate batteries, lithium titanate batteries, and so on. Because of their relatively high energy density, ternary lithium batteries are widely used in passenger cars. Manufacturers include Panasonic and LG from abroad, CATL and BYD in China; lithium iron phosphate is generally used in passenger cars due to its outstanding safety, and the representative manufacturer is BYD. Lead-acid batteries are no longer used as power lithium-ion batteries in automobiles. In the 1990s, France used to subsidize lead-acid battery electric vehicles on a large scale, and it turned out to be the wrong technical route. In the craziest period of domestic fraud, some manufacturers also introduced buses equipped with lead-acid batteries. Sodium-sulfur batteries for vehicles are currently only experimental products. There are also many types of fuel power batteries, such as hydrogen fuel power cells, high temperature fuel power cells, straight methanol fuel power cells, methanol reforming hydrogen fuel power cells, metal fuel power cells, and so on. At present, hydrogen fuel power batteries are the mainstream in the passenger car category. They represent manufacturers such as Toyota and Hyundai, and the biggest feature can achieve full life cycle pollution-free (from the beginning of raw material manufacturing to the final recycling). The fuel hydrogen used has the characteristics of high energy density and zero pollution. The disadvantage is that the current cost is very high, and the volumetric power density is limited. Take Hyundai NEXO, the representative of fuel-powered battery vehicles, as an example. The volume of the fuel-powered battery system of NEXO is about the same as a V6 engine, but the output power is only in the early 100KW, about 140 horsepower. The Infiniti Q70L, which is roughly equivalent in price, can reach 338 horsepower.
