We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries.
The electrode and cell manufacturing processes directly determine the comprehensive performance of lithium-ion batteries, with the specific manufacturing processes illustrated in Fig. 3. Fig. 3.
Furthermore, the study reveals that the negative electrode material’s elastic modulus significantly impacts electrode stress, which can be mitigated by reducing the material’s elastic modulus. This research provides a valuable reference for preventing battery aging due to electrode stress during design and manufacturing processes.
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.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
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.
