The voltage of a lithium battery is closely related to the electrode potentials of its cathode and anode materials. Variations in voltage among lithium batteries using different materials primarily stem from the following factors: Impact of Electrode Materials’ Chemical Properties Lithium batteries operate through the movement of lithium ions between the cathode and anode during charging and disch...

A lithium-ion battery is primarily composed of a cathode, anode, electrolyte, and separator. During charging, lithium ions de-intercalate from the cathode material, migrate through the electrolyte, and intercalate into the anode material. During discharging, lithium ions move in the reverse direction, de-intercalating from the anode and returning to the cathode through the electrolyte. This repeat...

Lithium plating refers to the detrimental phenomenon where lithium ions fail to intercalate into the graphite anode during charging processes, instead undergoing electrochemical reduction to form metallic lithium deposits. This results in the formation of characteristic silver-gray lithium metal layers or dendritic lithium crystals on the anode surface. Conventionally, battery disassembly has been...

In lithium battery manufacturing, the often-overlooked A/B-side coating misalignment issue during the coating process significantly affects battery capacity, safety, and cycle life. Misalignment refers to inconsistencies in the positional alignment or thickness distribution of coatings on the front and back sides of electrodes, which can lead to risks such as localized lithium plating and mechanic...
