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.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
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.
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.
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.
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.
