Lithium-ion battery electrode sheet baking process main content Baking is one of the core processes in the manufacturing of lithium-ion batteries. Its core task is to remove moisture and organic solvents (such as NMP or deionized water) from the coated positive and negative electrode sheets. Residual solvents not only damage the microstructure of the electrodes, but also lead to increased…

Lithium-ion battery slitting process main content Slitting is a key process in the manufacturing of lithium-ion batteries, responsible for cutting the rolled electrode sheets into narrow-width electrode sheets that meet the design specifications of the battery cells. The slitting accuracy directly affects the dimensional consistency of the battery, the quality of the electrode sheet edge and safety. Especially in small-scale…

Lithium-ion battery crushing process main content Rolling (roller pressing) is a crucial process in the manufacturing of lithium-ion batteries, responsible for compacting the coated aluminum foil (positive electrode current collector) and copper foil (negative electrode current collector), which directly affects the energy density, cycle life and high-rate performance of the battery. In high-power application scenarios such as lithium-ion start-stop batteries…

Lithium-ion Battery Coating Process main content Coating is one of the core processes in the manufacturing of lithium-ion batteries. Its core task is to evenly coat the positive and negative electrode pastes on the surfaces of aluminum foil (positive electrode current collector) and copper foil (negative electrode current collector) to form electrode sheets. The coating quality directly affects the energy…

Positive Electrode homogenization main content Cathode homogenization is one of the core steps in the manufacturing of lithium-ion batteries. Its purpose is to mix cathode active substances (such as lithium iron phosphate, lithium cobalt oxide, ternary materials, etc.), conductive agents, binders and solvents, etc. to form a uniform slurry. This process directly affects the energy density, cycle life and safety…

Detailed Explanation of the Negative Electrode homogenization Process main content Negative electrode homogenization is the first key process in the manufacturing of lithium-ion batteries, directly determining the microstructure of the electrode and the performance of the battery. The core objective is to uniformly disperse active substances such as graphite, conductive agents, binders and other raw materials in the solvent to…
