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...
Energy density refers to the amount of energy stored in a certain unit of space or mass of matter. The energy density of a battery is the electrical energy released by the average unit volume or mass of the battery. The energy density of a battery is generally divided into two dimensions: gravimetric energy density and volumetric energy density. What is energy density? Energy density refers to the...
In the digital age, current electronic products and new energy electric vehicles are inseparable from lithium batteries. The development path of lithium batteries originated in Europe and the United States, grew in Japan and South Korea, and was finally dominated by China. (1) Brief introduction More than 10 years ago, the lithium battery market was monopolized by Japanese companies, with a batter...
Lithium-ion battery pulping process (1) - pulp dispersion and stabilization mechanism According to the different states of matter, the phase states of matter can usually be divided into solid, liquid and gaseous states. In addition, there is another special state of matter between solid and liquid states. Nobel Prize winner Pierre-Gilles de Gennes Such substances are called 'soft substances'. Soft...
Lithium-ion battery pulping process (2) - pulp dispersion and stabilization mechanism 3.1 Van der Waals forces According to the London theory, when the wave electrons are distributed around an atom or molecule, a temporary dipole is generated. This temporary dipole causes the adjacent atoms or molecules to generate dipoles, and causes van der Waals attraction between two neutral atoms or molecules...
Detailed explanation of the composition, classification and industrial chain of lithium batteries First, the composition of lithium-ion battery structure Lithium-ion battery is a secondary chemical battery (rechargeable chemical battery) whose positive and negative electrodes are composed of two different substances, which can be used for reversible insertion and extraction of lithium ions. During...
Foldable solar cell "transparent paper" may change the future of solar panels Nomiya, an associate professor at the Institute of Industrial Science, Osaka University, Japan, has also developed a "translucent paper" that has excellent properties that materials such as plastic film and thin glass do not have. In order to take full advantage of its characteristics, Associate Professor Nogi has also d...
1. The optimal placement angle of solar photovoltaic panels is 45 degrees. 2. When installing solar panels, the first thing to consider is the choice of direction. If you choose the wrong direction, the angle is useless. If the direction is wrong, it will not receive sunlight at all. Now common solar devices, such as solar street lights, have been carefully observed and found to be in the south di...
