“…Considerable research has focused on seven classes of inorganic SSEs, including LISICON-like materials, argyrodites, garnets, NASICON-like materials, lithium nitrides, lithium hydrides, perovskites, and lithium halides. [39][40][41][42][43][44][45][46][47][48][49] A pioneering work developed the LiRAP Li 3 OA (A = Cl, Br) as a superionic solid electrolyte, [27] achieving a Li ionic conductivity as high as 1.94 × 10 −3 S cm −1 in Li 3 OCl 0.5 Br 0.5 . Importantly, the performance of LiRAPs can be improved via various structural design strategies.…”

ABX3 perovskites, as the largest family of crystalline materials, have attracted tremendous research interest worldwide due to their versatile multifunctionalities and the intriguing scientific principles underlying them. Their counterparts, antiperovskites (X3BA), are actually electronically inverted perovskite derivatives, but they are not an ignorable family of functional materials. In fact, inheriting the flexible structural features of perovskites while being rich in cations at X sites, antiperovskites exhibit a diverse array of unconventional physical and chemical properties. However, rather less attention has been paid to these “inverse” analogs, and therefore, a comprehensive review is urgently needed to arouse general concern. Recent advances in novel antiperovskite materials and their exceptional functionalities are summarized, including superionic conductivity, superconductivity, giant magnetoresistance, negative thermal expansion, luminescence, and electrochemical energy conversion. In particular, considering the feasibility of the perovskite structure, a universal strategy for enhancing the performance of or generating new phenomena in antiperovskites is discussed from the perspective of solid‐state chemistry. With more research enthusiasm, antiperovskites are highly anticipated to become a rising star family of functional materials.

Fast Lithium Ion Conduction in Lithium Phosphidoaluminates

Solid electrolyte materials are crucial for the development of high‐energy‐density all‐solid‐state batteries (ASSB) using a nonflammable electrolyte. In order to retain a low lithium‐ion transfer resistance, fast lithium ion conducting solid electrolytes are required. We report on the novel superionic conductor Li9AlP4 which is easily synthesised from the elements via ball‐milling and subsequent annealing at moderate temperatures and which is characterized by single‐crystal and powder X‐ray diffraction. This representative of the novel compound class of lithium phosphidoaluminates has, as an undoped material, a remarkable fast ionic conductivity of 3 mS cm−1 and a low activation energy of 29 kJ mol−1 as determined by impedance spectroscopy. Temperature‐dependent 7Li NMR spectroscopy supports the fast lithium motion. In addition, Li9AlP4 combines a very high lithium content with a very low theoretical density of 1.703 g cm−3. The distribution of the Li atoms over the diverse crystallographic positions between the [AlP4]9− tetrahedra is analyzed by means of DFT calculations.

The phase relationships of the quasibinary systems CUC1-M U C1 2 (M" = Mn, Cd) were studied by high-temperature X-ray methods and difference thermal analyses (DTA). Four phases have been established: CdCl 2 -type M"_ x Cu 2x Cl 2 and α-CuI-type Cu\_ y M". Sy Cl solid solutions (above 361 and 321 °C, respectively), and β-and y-CuCl with negligible solubility for M u . The phase widths of the Cd containing compounds are 0 < χ < 0.35 at 25°C, 0 < χ < 0.6at315°C, and 0 < y < 0.4at420°C; those of the manganese compounds are similar. The crystal structures of α-CuI-type Cu 2 MnCl 4 at 400° C and of Mn 0 .84Cu 0 . 32 Cl 2 and y-CuCl both at 60° C were determined by means of neutron powder diffraction. The structures were refined by Rietveld's method to final R, = 1.7, 6.0, and 2.5%, respectively. The hitherto unknown high-temperature α-polymorph of CuCl can be stabilized by Mn" and Cd". The α-CuI-type solid solutions are fast Cu + ion conductors with conductivities of σ > 10 _I Ω~ι cm -1 above 350° C.
