The high-efficiency recovery technology of valuable metals from waste lithium-ion batteries has become a research hotspot at home and abroad. Aiming at the current status of the recovery technology of valuable metals in waste lithium-ion batteries, this paper introduces the research methods of pretreatment and cathode material treatment in the recovery process of valuable metals, and briefly evalu...
1.3 Separation, Recovery and Utilization of Valuable Metals The recovery and utilization of valuable metals in waste lithium-ion batteries is mainly the recovery of positive active materials. Cathode recycling and processing methods mainly include biological method, high temperature combustion method, acid dissolution method and electrochemical dissolution method. 1.3.1 Biological Law The biologic...
From the classification of lithium batteries, understand the mainstream technology of power batteries in three minutes "Although lithium iron phosphate is good, it is not as good as ternary batteries." The power batteries of new energy vehicles can be divided into secondary batteries (including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium batteries) an...
We often talk about ternary lithium batteries or iron-lithium batteries, which are named after the positive active material. The six common types of lithium batteries include: lithium cobalt oxide, lithium manganate, lithium nickel cobalt manganate (NCM), lithium nickel cobalt aluminate (NCA), lithium iron phosphate, and lithium titanate. 1. Lithium cobalt oxide (LiCoO2) Its high specific energy m...
A lithium-ion battery is a rechargeable battery that works by moving lithium ions between a positive and negative electrode. Traditionally, the process of lithium ions entering the cathode material is called intercalation, and the process of lithium ions leaving the cathode material is called de-intercalation; the process of lithium ions entering the cathode material is called intercalation, and t...
1. Good safety performance The structure of the polymer lithium-ion battery is an aluminum-plastic flexible package, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated. 2. Light weight The polymer battery is 40% lighter than the steel case lithium-ion battery of the same c...
Solar energy is an inexhaustible and inexhaustible renewable energy source for mankind, and plays an important role in the long-term energy strategies of countries around the world. Thin-film power generation relies on thin-film solar cell chips that are light, thin and flexible. Crystalline silicon power generation has high energy conversion efficiency, but the solar panel must be thick enough. S...
Electrochemical energy storage battery is an extremely important electrical energy storage method. Energy storage battery is a device that stores electrical energy through the mutual conversion of chemical energy and electrical energy. Up to now, the commonly used battery systems have certain problems. For example, traditional lead-acid batteries contain strong pollutants such as heavy metals; the...
