Which battery is the best for electric vehicle battery technology?

The emergence of the electric vehicle industry has driven the development of electric vehicle batteries, and the two complement each other. Electric vehicles need batteries, and batteries can only realize their value in electric vehicles. So which electric vehicle battery technology is strong? Many electric vehicle owners will pay attention to the battery problem. Today, the power lithium ion battery shell technicians will analyze with you: Which is the strong electric vehicle battery technology? 1. The power lithium battery lithium battery uses light metal lithium, Although it does not contain harmful heavy metals such as mercury and lead, it is environmentally friendly and has little environmental pollution. But in fact, as a cathode material and electrolyte containing metals such as nickel and manganese, lithium batteries in the United States are listed as a battery that contains flammable, leaching toxicity, corrosive, reactive, toxic and harmful batteries. Types of batteries, because the recycling process is more complicated, leading to higher costs, so the current recycling rate is not high, and the impact of waste batteries on the environment. 2. Hydrogen fuel power battery Hydrogen fuel power battery is a highly efficient and clean energy source, which not only emits very little water, but also is very clean, so there is no water pollution problem. At the same time, unlike the engine, the fuel power cell does not convert thermal energy into mechanical energy, but directly converts chemical energy into electrical energy and thermal energy, which makes the energy conversion efficiency high and low noise. Hydrogen fuel power batteries do not require large and complex configurations for power generation, and battery stacks can be assembled in modules. 3. Ni-MH rechargeable batteries As the cadmium in nickel-cadmium batteries is toxic, which makes the disposal of waste batteries complicated and pollutes the environment, it will gradually be replaced by nickel-hydrogen rechargeable batteries (ni-mh) made of hydrogen storage alloys . In terms of battery power, the battery power of the same size Ni-MH rechargeable battery is about 1.5 to 2 times that of the Ni-Cd battery, without cadmium pollution. At present, Ni-MH rechargeable batteries have been widely used in small portable electronic devices such as mobile communications and notebook computers. Ni-MH batteries are composed of hydrogen ions and nickel ions. The battery capacity is more than 30% larger than the nickel-cadmium battery, lighter than the nickel-cadmium battery, and has a long service life and no pollution to the environment. 4. The low energy density of supercapacitors is one of the bottlenecks in its application, which is only 1/20 of that of lithium batteries, which is about 10wh/kg. Therefore, it cannot be used as an important power source for electric vehicles, but is important as an auxiliary power source, and is mainly used for quick start devices and braking energy recovery devices. The charge transfer of supercapacitors occurs on the surface of the electrode active material, so the capacity attenuation at temperature is very small, while the capacity of lithium batteries usually attenuates 70% at low temperatures. 5. Aluminum-air battery The anode active material of aluminum-air battery is metal aluminum with abundant content, low price and environmental protection. The anode active material is oxygen in the air, and the anode capacity can be seen to be infinite. Therefore, aluminum-air batteries have the advantages of light weight, small size, and long service life. Air electrode polarization and aluminum hydroxide deposition are important obstacles to the marketization of metal-air batteries. At present, it is still in the experimental stage, and there is still a long way to go before commercial promotion. From the above analysis, we can see the advantages of electric vehicle battery technology. Although the recycling and reuse rate of lithium batteries is not high, it is undeniable that lithium batteries are the most widely used and most mature technology in electric vehicles. In addition, researchers have been committed to the recycling of lithium batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
