“…[52] A pulsed laser deposition (PLD) method was used to fabricate a Li 3 OCl film with an ionic conductivity of 0.9 × 10 −5 S cm −1 at room temperature. [53] Subsequent studies improved the room temperature ionic conductivity to 2.0 × 10 −4 S cm −1 [54] before the feasibility of using the optimized Li 3 OCl film in a real battery LiCoO 2 ||Li 3 OCl||C was demonstrated. The battery has an initial discharge capacity of 120 mA h g −1 and a discharge efficiency of 95% after the second cycle.…”

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.

“…), has been developed as a promising solid electrolyte. [15][16][17][18][19][20] This class of electrolytes accommodates a large number of Li ions in the crystal lattice and the Li ions can move easily by introducing certain amounts of crystal defects, such as Li + and Clvacancies. The most important advantages of the LiRAP electrolyte include (1) high ionic conductivity and low energy barrier for Li transport, (2) low electronic conductivity (Li 3 OCl with a band gap exceeding 5 eV [ 16,17 ] ) with minimum self-discharge for long shelf life, (3) wide electrochemical working windows beyond 5 V compatible with high-potential cathodes, (4) stable operation at high temperatures up to 275 °C, and (5) environmental friendliness.…”

“…We have recently reported the preparation of Li 3 OCl fi lm by pulsed laser deposition (PLD), and the ionic conductivity was notably enhanced in comparison with that of its bulk counterpart. [ 19 ] In that work, we used the stoichiometric Li 3 OCl compound as the target, where the conditions to prepare target are critical for obtaining high performance Li 3 OCl fi lms. Furthermore, the process to prepare the Li 3 OCl target is energy/time consuming (>300 °C for at least 48 h).…”

Antiperovskite Li3OCl superionic conductor films are prepared via pulsed laser deposition using a composite target. A significantly enhanced ionic conductivity of 2.0 × 10−4 S cm−1 at room temperature is achieved, and this value is more than two orders of magnitude higher than that of its bulk counterpart. The applicability of Li3OCl as a solid electrolyte for Li‐ion batteries is demonstrated.

Li-ion microbatteries find wide applications in microdevices. It is of importance to develop electrode materials with high areal capacity, excellent rate capability and superior safety for microbatteries. TiO 2 nanowire arrays satisfy the requirements of high areal capacity, short transport lengths and superior safety for microbatteries, but their areal/volumetric capacity is hindered by the insufficient surface area. TiO 2 nanotrees can effectively eliminate these disadvantages of TiO 2 nanowires; however, the electrochemical performances of TiO 2 nanotrees for Li-ion microbatteries remain unexplored. It is highly desired yet challenging to construct two-dimensional TiO 2 nanobranches with ultrathin thickness and large length on nanoarrays, to maximize the surface area and structural hierarchy of electrodes. Herein, we developed a novel synthetic strategy to fabricate TiO 2 nanotrees by depositing anatase/TiO 2 (B) mixed phase ultrathin nanobelts onto single-crystalline anatase nanowire arrays. The nanobelt branches were several nanometers in thickness and 200-260 nm in length. The growth process and the electrochemical mechanism were investigated. The unique nanoarchitecture and optimal phase structure endow the electrode with high areal capacity and rate capability, which is the best performance for TiO 2 nanowire arrays ever documented. The 2nd discharge capacity of the TiO 2 nanotrees at 0.1 mA cm -2 is ca. 267 μAh cm -2 , corresponding to a volumetric capacity of 330 mAh cm -3 . The TiO 2 nanotrees have an areal capacity of 205, 141, 97 and 69 μAh cm -2 at the current density of 0.5, 2.0, 5.0 and 10.0 mA cm -2 , respectively. The capacity can maintain stable for 400 charge-discharge cycles at 1.0 mA cm -2. The present strategy may give hints to elegant electrode designs for energy applications.This journal is
