About this Research Topic
Solid-state lithium-ion batteries (SSBs) show intrinsic safety and potential high energy density advantages over traditional liquid batteries, have been regarded as one of the most promising energy storage devices, toward the wide applications of electric vehicles and large-scale clean energy storage. The cycling performance and practical energy density of SSBs, however, are still far below the liquid batteries, which has been one of the bottlenecks of SSBs.
The main issues that hinder the application of SSBs remain at the solid-state electrolytes (SSEs) and the interfaces between SSEs and electrodes. Though some kinds of SSEs has reached the ionic conductivity of liquid electrolytes. However, the electrochemical window, atmosphere stability and interface properties are far behind expectation. Dislike liquid electrolytes with high wettability, SSEs has high modulus that shows hard contact model and limited contact area with electrodes. In addition, due to the chemical potential, crystal lattice and ionic transport mismatch between SSEs and electrodes, undesirable side reactions and resultant in-situ formed high resistance interphases, space charge layer that hinders that carrier transfer (Li+/e-) at the interfaces.
The topic scope of this Research Topic focuses on:
• the designing and fabrication of thin, flexible and high ionic conductivity SSE;
• electrode active materials optimization;
• electrochemical stability, mechanical compatibility and charge transfer kinetics at the interfaces between SSEs and electrodes;
• cell performance evaluation and cycling performance prediction based on artificial intelligence (AI).
