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.
The methods of coating the positive electrode and the negative electrode are the same as previously described. The following methods are now being used for making the cell core or electrode stack: The positive electrode, the negative electrode, and the separator are wound into a coil and then heated and pressed flat.
The influences of different technologies on electrode microstructure of lithium-ion batteries should be established. According to the existing research results, mixing, coating, drying, calendering and other processes will affect the electrode microstructure, and further influence the electrochemical performance of lithium ion batteries.
Computer simulation technology has been popularized and leaping forward. Under this context, it has become a novel research direction to use computer simulation technology to optimize the manufacturing process of lithium-ion battery electrode.
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.
