The principle of laser cleaning is to utilize the characteristics of laser beam with large energy density, controllable direction and strong convergence ability. The laser interacts with contaminants such as oil stains, rust spots, dust residue, coatings, oxide layers or film layers attached to the workpiece base, and is separated from the workpiece base in the form of instantaneous thermal expans...

Lithium-ion Battery Anode Material Classification As one of the key materials for lithium-ion batteries, negative electrode materials need to meet multiple conditions. The Li intercalation and deintercalation reaction has a low redox potential to satisfy the high output voltage of lithium-ion batteries. During the process of Li intercalation and deintercalation, the electrode potential changes lit...

Why are all-solid-state batteries an industry trend? High security: The safety issues of liquid batteries have always been criticized. The electrolyte is easily flammable under high temperature or severe impact. Under high current, lithium dendrites will also appear to pierce the separator and cause short circuit. Sometimes the electrolyte may undergo side reactions or decompose at high temperatur...

What is calendering： Calendering of battery electrodes is an important step in the production process of lithium-ion batteries, and its purpose is to obtain electrodes that meet design requirements. Calendering is a necessary process. After the electrode coating and drying, the peeling strength between the active material and the current collector foil is low. At this time, it needs to be calender...
