Solid-state batteries offer several advantages over conventional liquid electrolyte-based batteries, particularly in terms of safety, energy density, packaging, and operable temperature range.
By using solid state electrolytes instead of flammable and potentially toxic organic liquid electrolytes, solid-state batteries could mitigate the risk of fire and improve overall safety. However, the electrochemistry and operation mechanisms of solid-state batteries differ significantly from conventional lithium/sodium ion batteries. This creates a need for a better understanding of the failure mechanisms that may occur in solid-state batteries, as they are not yet well understood. Therefore, it is crucial to investigate the dynamic evolution of electrodes, solid-state electrolytes, and their interfaces and interphases during the cycling process of solid-state batteries.
This special issue wants to provide a systematic and in-depth understanding of chemical/electrochemical reaction and degradation processes in the solid-state batteries.
1. The thermodynamic, kinetic, electrochemical, chemomechnical, structural stability of dendrite nucleation and growth in solid-state batteries via advanced in-situ TEM techniques.
2. Real time observations of reaction and degradation of solid-state batteries via in-situ TEM and variety advanced TEM techniques.
3. Novel electro-chemo-mechanical coupling phenomena through variety advanced TEM techniques.
4. Interface evolution between different components inside solid-state batteries.
5. Novel in-situ TEM techniques developed to investigate solid-state batteries under a real working condition.
6. In situ measurement of chemical/physical/mechanical properties of different components inside solid-state batteries.

2. Cryo-TEM to investigate beam sensitive and air sensitive battery materials, e.g., lithium metal anode, solid-state electrolyte, solid electrolyte interphase, and cathode electrolyte interphase.
3. 4D-STEM with novel functions to get orientation mapping of battery materials at very high resolution, strain mapping of battery materials, electrostatic potential of battery materials, and differential phase contrast makes low-Z elements imaging possible for lithium.
4. Cryo-(S)TEM tomography to investigate 3D structural/chemical information of solid-state battery materials.
