Particle size-dependent bulk and grain-boundary contributions in Li 2 O–B 2 O 3 –Al 2 O 3 solid electrolytes

Key Points

• The aim is to investigate how particle size affects lithium conduction in solid electrolytes, specifically focusing on bulk and grain boundaries.
• Analyzed conduction pathways in Li2O–B2O3–Al2O3 solid electrolytes.
• Evaluated bulk and grain-boundary contributions.
• Used schematic representations to illustrate conduction mechanisms.
• Demonstrated that particle size significantly influences lithium conduction pathways.
• Identified distinct contributions from bulk and grain boundaries based on particle size.
• Indicated that smaller particles enhance lithium conductivity due to increased grain boundary effects.
