There are new ways to recycle and regenerate lithium batteries

Scientists have observed in the study of the aging mechanisms affecting current lithium-ion batteries that the loss of lithium over time is one of the main causes of performance degradation. With this in mind, they have developed and tested a "regenerative" process that promises to reduce the significant cost and complexity associated with recycling battery components and materials. As energy storage technology plays an increasingly important role in our daily lives, and the popularity of electric vehicles has increased dramatically, the availability of materials for the manufacture of lithium-ion batteries, their safe handling and recycling strategies are increasingly important. problem. Although Europe and other regions began to introduce laws requiring

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.

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,
