According to the existing research, each manufacturing process will affect the electrode microstructure to varying degrees and further affect the electrochemical performance of the battery, and the performance and precision of the equipment related to each manufacturing process also play a decisive role in the evaluation index of each process.
Battery electrodes are the two electrodes that act as positive and negative electrodes in a lithium-ion battery, storing and releasing charge. The fabrication process of electrodes directly determines the formation of its microstructure and further affects the overall performance of battery.
Chemical reactions can cause the expansion and contraction of electrode particles and further trigger fatigue and damage of electrode materials, thus shortening the battery life. In addition, the electrode microstructure affects the safety performance of the battery.
The electrode manufacturing procedure is as follows: battery constituents, which include (but are not necessarily limited to) the active material, conductive additive, and binder, are homogenized in a solvent. These components contribute to the capacity and energy, electronic conductivity, and mechanical integrity of the electrode.
