With the continuous development of the pure electric vehicle industry, the number of electric vehicles is also steadily increasing. However, pure electric vehicles are also means of transportation, and they will one day be scrapped as their useful life increases. So, which parts of pure electric vehicles are most valuable when scrapped?
Actually, to answer this question, we first need to understand the most expensive part of the production cost of pure electric vehicles. At present, the most expensive part of the pure electric vehicle production process is the three-electric system, and in the three-electric system, the cost of power batteries is higher. According to the current cost analysis of pure electric vehicles, power batteries account for about 30-40% of the total production cost of pure electric vehicles.ctrics. Therefore, the power batteries of pure electric vehicles are relatively more valuable.
At present, pure electric vehicles are mainly equipped with ternary lithium batteries, and some use lithium iron phosphate batteries. For ternary lithium batteries, the elements that can be recycled include lithium, nickel, cobalt and manganese, and the qualities of lithium, nickel and cobalt elements in the positive electrode of ternary lithium batteries are much higher than those natural minerals. In other words, the ternary cathode material has greater regeneration value, while for lithium iron phosphate batteries, the main element is lithium.
In addition to having a regeneration value, power batteries can also be used twice. Because even if pure electric vehicles are scrapped, the batterypower battery always has the function of storing electricity, so the power battery can be used as an energy storage device. For example, Japan used batteries removed from Nissan Leaf electric vehicles to light streets. from the town of Namie. Reusing used batteries can also reduce the environmental impact and improve the economic benefits of the new energy industry.
In addition to the power battery, the frame, the trielectric system, the wheels, etc. are included. can be recycled. Of course, in this part of recycling, except for a small amount of precious metals, the rest is recycled with ordinary metals. Compared to electric batteries, the value is not very high. Therefore, the battery of a pure electric vehicle is more valuable once discarded.

No one steals lithium batteries from electric vehicles.
Actually, the cost of lithium batteries is much higher than that of lead-acid batteries, but the recycling price of lead-acid batteries has increased, but almost no one recycles batteries lithium. !
First, let's look at lead acid batteries. They can be recycled in automobile repair shops and waste sorting centers. For what ? That's because recycling lead can easily generate business value: grab a screwdriver and. remove the old batteries, open it, pour out the acid, take out the most valuable lead plates and sell them to earn money.
However, there is no way to recycle lithium batteries. The reason is that the lithium battery recycling process is too complicated. Intermediate products per haute added value such as positive electrode materials, negative electrode materials, electrolytes and separators are directly recovered from waste lithium batteries. Marketing is very difficult. Additionally, the materials and formulas of lithium batteries from different manufacturers are different, making recycling even more difficult.
Overview of lithium-ion batteriesLithium-ionThe traditional structure of a battery includes a graphite anode, a lithium-ion metal oxide cathode, and an electrolyte (a lithium salt solution dissolved in a solvent organic). The most common lithium-ion battery uses carbon as the anode, a solution of lithium hexafluorophosphate dissolved in ethylene carbonate and dimethyl carbonate as the electrolyte, and lithium manganese dioxide as the cathode. It is light and strong, has a high specific energy and. the tensionn of the cell is approximately 3.7 V. .
Compared with nickel-metal hydride batteries, lithium-ion batteries have relatively high operating voltage and large specific energy, which is 3 times that of nickel-metal hydride batteries. Lithium-ion batteries are small in size, light in weight, have a long service life, low self-discharge rate, no memory effect and no pollution; the numerical range of a single battery performance indicator is wide, because lithium-ion batteries have more; electrode combinations, and they exist. There are some performance differences.
Lithium-ion batteries can be divided into two types: lithium-ion batteries and lithium-polymer batteries. The cathode materials of lithium ion batteries mainly include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, lithium iron phosphate,etc. Anode materials mainly include graphite, lithium titanate, etc.
