The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

The application and promotion of electrochemical batteries have changed the current industrial pattern. Among them, lithium batteries have developed rapidly in the field of power and energy storage. At present, the debate on the priority of the two popular lithium batteries, "lithium iron phosphate battery" and "ternary lithium battery", has never stopped. This year, the two are pushed to the forefront again.

Lithium ion batteries have been widely used in notebook computers, video cameras, mobile communications and other portable appliances due to their unique performance advantages. At present, the large capacity lithium ion battery developed has been put into trial use in electric vehicles, and is expected to become one of the main power sources of electric vehicles in the 21st century, and be applied in artificial satellites, aerospace, energy storage and other fields. So, what are the main advantages of lithium batteries for electric vehicles?

The power recovery decision-making consultation salon co sponsored by the Beijing Association for Science and Technology and the Literature and Information Center of the Chinese Academy of Sciences was held in Beijing Green Space Center yesterday. Fei Weiyang, academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of pure electric drive has made great progress, and the core technology of electric vehicles represented by lithium ion has made a major breakthrough. However, the massive application of lithium batteries will also lead to the retirement of a large number of lithium batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for lithium battery recycling to achieve safe and efficient disassembly and overall recovery of valuable metals and prevent secondary pollution.

With the popularity of electric vehicles, more and more people begin to pay attention to the battery. The battery is the energy storage warehouse of electric vehicles. Electric vehicles convert electric energy into chemical energy when charging and store it in the battery. When using electric vehicles, the motor converts the chemical energy in the battery into mechanical energy, so that electric vehicles can run on the road. Since the battery is the power source of electric vehicles, What kinds of batteries are currently used in electric vehicles and which battery is better?
