In conclusion, self-healing polymers implemented in electrolytes or electrodes may be able to optimize the cycle stability and prolong the lifetime of the batteries, while simultaneously improving the safety. However, research in this field is still in its initial stage and far from actual commercialization.
Multiple requests from the same IP address are counted as one view. The integration of polymer materials with self-healing features into advanced lithium batteries is a promising and attractive approach to mitigate degradation and, thus, improve the performance and reliability of batteries.
The basic working principle of the LiB is schematically presented in Figure 2. Li-ion rechargeable batteries consist of two electrodes, anode and cathode, immersed in an electrolyte and separated by a polymer membrane (i.e., separator) in order to electrically isolate the electrodes from each other.
Furthermore, a good compatibility of the electrode materials should be provided to ensure the formation of a stable SEI layer, thus prolonging the cycling stability of the battery.
In fact, several studies have already shown that the richness of organic and polymer chemistry still provides avenues for further improvements to develop polymer-based electrolytes that satisfy all the requirements for their successful exploitation in next-generation lithium batteries.
The sustainability of the batteries can be improved with the introduction of biomimetic materials, which should be developed together with self-healing functionalities. Finally, the extrinsic self-healing needs triggering acts which are based on continuous monitoring using sensors built in the battery cell.
