Visualization and evaluation of lithium diffusion at grain boundaries in Li0.29La0.57TiO3 solid electrolytes using secondary ion mass spectrometry† Understanding Li diffusion at interfaces in solid-state Li batteries is essential to improving their performance (e.g., rate capabilities and energy densities). However, the visualization of Li diffusion at grain boundaries has been impossible due to the lack of experimental techniques.

Impact of intentional composition tuning on the sintering property of Ca-Bi co-doped Li7La3Zr2O12 for co-fired solid-state battery Naohiro Hayashi,   Ken Watanabe,   Tsuyoshi Ohnishi,   Kazunori Takada  and  Kengo Shimanoe   Abstract Li7La3Zr2O12 (LLZ) is a promising candidate electrolyte for co-fired all-solid-state Li-ion batteries. However, its application is hindered by the reaction between LLZ and electrode materials during high-temperature sintering.
