In the field of lithium battery research, many beginners often get confused about the naming of “anode” and “cathode”: Why, when studying anode materials, is lithium metal used as the cathode in experiments? Since the tested anode material gains electrons during testing, why is it still called the “anode”? What is the difference between researching…

In the research, manufacturing, and failure analysis of lithium batteries, the term “lithium plating” frequently appears. Simply put, lithium plating occurs when lithium ions, which should normally intercalate into the anode active material, are abnormally reduced to metallic lithium and deposited on the anode surface or the separator. As the deposited lithium accumulates, it can…

1.Introduction Fast charging is mainly achieved through either high-voltage charging or high-current charging. High-voltage charging must be implemented under the premise of improving the vehicle’s insulation level and the robustness of electronic components (battery, motor, and electronic control systems), which significantly increases the production cost of electric vehicles. High-current charging also faces issues such as…
