New energy vehicle battery recycling chaos investigation: 200000 tons of retired batteries into the "black market"

New energy vehicles are becoming a hot "meat and potatoes". In 2020, 1.36 million new energy vehicles were sold, and in the first quarter of this year, it increased 2.8 times year-on-year, with sales reaching 515000 vehicles. Compared with the sales data, the investment market is even hotter. In addition to the high market value of the three new car-making forces, Baidu and Xiaomi have successively announced "entering the circle" of new energy vehicles since the beginning of this year. However, as an important part of the new energy vehicle industry, retired battery recycling hidden risks. Industry insiders pointed out that by 2020, my country's cumulative decommissioning of power batteries will be about 200000 tons, of which a large number will flow into informal channels such as small workshops, bringing safety and environment.

Tell you why lithium iron phosphate power lithium battery will fail

As a competitive cathode material for electric vehicles, lithium iron phosphate has attracted a lot of attention. Understanding the failure cause or mechanism of lithium iron phosphate batteries is very important for improving battery performance and its large-scale production and use. This paper reviews the research progress of lithium iron phosphate power battery failure in recent years. The effects of impurities, formation methods, storage conditions, recycling, overcharge and overdischarge on battery failure are discussed. Failure in the production process of 1. In the production process, personnel, equipment, raw materials, methods, and the environment are the main factors affecting product quality, and the production process of LiFePO4 power batteries is no exception.

How is the lithium battery charged and what is the principle?

The lithium ion battery is generally a battery using lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, and a non-aqueous electrolyte. The mobile phones we usually use are almost all lithium batteries. At present, the power supplies of the more popular electric vehicles on the market are mostly lithium iron phosphate batteries. How do lithium batteries charge and discharge? First of all, let's understand the structure of lithium batteries. Lithium batteries are generally composed of positive electrodes, negative electrodes, electrolyte and separators. In daily life, our common mobile phone lithium batteries are square, and the batteries in electric vehicle battery packs are generally round. There are other shapes. Laminated and wound type. The four contacts on the common mobile phone battery,

Power battery opportunities under the "ground stall economy"

The "stall economy" is instantly popular. As one of the mobile carriers of stalls, new energy vehicles are also "hot. As the ground stall economy heats up, the relevant vehicle supporting battery enterprises may benefit. Recently, new energy car companies have started a series of publicity campaigns through the "stall economy": ① Wuling Motors has launched the electric version of Wuling Rongguang Wing to open the sales truck, starting at 76800 yuan. Although it is 21000 higher than the fuel price, it can be directly licensed in Beijing without ranking. Beijing Auto showcased a new energy model suitable for stalls-BAIC EV2. ③ Kaiyun Auto said that it will work with the Beijing Municipal Government in the near future.

Power battery cost structure split

Lithium batteries are divided into power batteries, energy storage batteries and consumer electronics batteries according to different application areas, and the cost structure of different types of lithium batteries is naturally different. Power battery in different positive and negative materials under its cost has a certain difference, the overall material cost accounted for a relatively large, labor costs, depreciation and other manufacturing costs accounted for a relatively small, while the material cost is mainly positive and negative materials, diaphragms, electrolytes and components. In the power battery cost model, we split the PACK cost into material cost and production cost, which in turn includes cell material,
