TL;DR: In this article, a mixture of cubic and tetragonal LLZ:Al was synthesized via conventional solid state reaction, which showed a maximum ionic conductivity of 3.5 S cm−1 at room temperature.

TL;DR: In this article, the micro-pillar splitting test was used for the first time on this material to determine the microscopic fracture toughness of single grains and compare it with conventional Vickers indentation fracture toughness, which represents macroscopic fracture toughness.

TL;DR: In this article, thin-film technologies open a pathway for manufacturing compounds of electrolyte and active material at lower processing temperatures, which are especially applicable for electrolyte layers since electrolytes require a high density while at the same time their thickness can be as thin as possible, provided that the separation of the electrodes is still guaranteed.

TL;DR: In this article, a completely dry co-sintering of LLZ and cathode active material (CAM) is presented, which is fast, free of any sintering additives and coatings and suitable to fabricate dense mixed cathodes, pure LLZ separators and multilayers of the two.

TL;DR: In this paper, the garnet Li7La3Zr2O12 (LLZO) was sintered in vacuum and Ar atmosphere with good mechanical stability and high phase purity, but kinetic de-mixing at the grain boundaries.
