1. Recycling of positive materials First of all, the positive active substance is effectively separated from the conductive aluminum foil in order to achieve the recovery of the positive electrode material. The current commonly used methods are: ① scraper; ② high temperature incineration; ③ organic solvent dissolving; ④ electrolytic stripping. The lithium -ion battery is used as a positive electrode with a lithium compound, and only lithium ion has no metal lithium. Usually it is lithium manganate, lithium co

A: Exercise: 1) The process requirements of the information supplier supply the material list, and the QC department also needs to test. Its component and impurities content satisfaction requires the processing of processing to settle for later use. 2) The pre -processing of the material is to eliminate pollutants and oxidation layers on the appearance of the original data to ensure the cleanliness of the original data. 3) The ingredients should be supplemented according to the goals of different situation

In recent years, researchers have worked hard to improve the energy density, value, safety, environmental impact, and trial life of lithium -ion battery packets, and design new types of batteries. So, when can battery technology have revolutionary breakthroughs? 1. The development of traditional lithium -ion battery packs is slow, and the space for further optimization is limited Consumer electronics, automobiles and power grid storage are currently three industries in battery applications. The editor referre

Lithium -ion battery discharge is based on lithium ions to spread from anode to cathode through an electrical appliance. This mobile mechanism is important based on the diffusion process: transmit lithium ions to the anode surface, transition to and pass through electrolytes, and transition to cathode and spread to cathode to cathode pole Essence Prowment is the biggest restrictions on high -current discharge and charging and low temperature performance. In addition, the volume change has occurred in the active ele

The status quo of the recycling of lithium -ion battery material Due to the acceleration of consumer electronics and the continuous promotion of lithium -ion batteries in the field of electric vehicles, a large number of waste lithium -ion batteries have appeared in recent years. The huge demand for lithium -ion batteries on the one hand will lead to a large amount of waste batteries on the one hand. How to deal with these waste lithium ion batteries can reduce its impact on the environment, which is an urgen

1. Lithium -ion battery material treatment Some materials used for secondary batteries, such as lithium ion, should be specially treated. The electrodes should be treated at high speed and will not damage the fragile active substances. In electrolytes, special consideration should be considered to prevent precipitation and corrosion gases. 2. Cam If you use a cylinder or AC servo actuator to construct a machine, the beat time is less than 1 second, and it is difficult to keep or maintain a stable state for

"American News today" recently said that the team of Stanford University is trying to create a new lithium ion battery. This battery allows electric vehicles to drive for 300 miles every time, and also increases the use time of mobile phone batteries triple. However, Cui Yi, a professor at Stanford University, said that it is estimated that the product is listed for 3 to 5 years. The Stanford team said that this battery is a high -purity lithium -ion battery made of nano -technology. Due to its light w

Since the beginning of this year, technology in the field of fuel power lithium batteries has made breakthroughs in succession; under the strong support of new technologies and policies for new energy vehicles, the capital market has continuously staged a boom in the hype of fuel power lithium batteries. Untry historical high. Following the progress of the high -energy density lithium sulfur battery in Metal in February this year, on August 22, Researcher Chen Jian, a researcher at the Dalian Institute of Chinese A

According to foreign media reports, the German government organized nearly 1.8 million euros, and in July 2021, the "Solis multi-layer soft bag battery lithium sulfur solid battery development" (SOLIS –Developmentoflith-SulphursolidStateBatteriesinmultilayerPouchccccc Ells) project, the purpose is to have a foreground The concept of battery concept is transformed from basic research to industrial applications.
