Beyond state-of-the-art lithium-ion battery (LIB) technology with metallic lithium anodes to replace conventional ion intercalation anode materials is highly desirable because of lithium’s highest specific capacity (3,860 mA/g) and lowest negative electrochemical potential (∼3.040 V vs. the standard hydrogen electrode). In this work, we report for the first time, to our knowledge, a 3D lithium-ion–conducting ceramic network based on garnet-type Li6.4La3Zr2Al0.2O12 (LLZO) lithium-ion conductor to provide continuous Li+ transfer channels in a polyethylene oxide (PEO)-based composite. This composite structure further provides structural reinforcement to enhance the mechanical properties of the polymer matrix. The flexible solid-state electrolyte composite membrane exhibited an ionic conductivity of 2.5 × 10−4 S/cm at room temperature. The membrane can effectively block dendrites in a symmetric Li | electrolyte | Li cell during repeated lithium stripping/plating at room temperature, with a current density of 0.2 mA/cm2 for around 500 h and a current density of 0.5 mA/cm2 for over 300 h. These results provide an all solid ion-conducting membrane that can be applied to flexible LIBs and other electrochemical energy storage systems, such as lithium–sulfur batteries.

Li2ZrO3-coated and Al-doped micro-sized monocrystalline LiMn2O4 powder is synthesized through solid-state reaction, and the electrochemical performance is investigated as cathode materials for lithium-ion batteries. It is found that Li2ZrO3-coated LiAl0.06Mn1.94O4 delivers a discharge capacity of 110.90 mAhg−1 with 94% capacity retention after 200 cycles at room temperature and a discharge capacity of 104.4 mAhg−1 with a capacity retention of 87.8% after 100 cycles at 55 °C. Moreover, Li2ZrO3-coated LiAl0.06Mn1.94O4 could retain 87.5% of its initial capacity at 5C rate. This superior cycling and rate performance can be greatly contributed to the synergistic effect of Al-doping and Li2ZrO3-coating.

All-solid-state lithium-ion batteries have great potential for improved energy and power density compared to conventional lithium-ion batteries. With extensive research efforts devoted to the development of inorganic superionic conductors, lithium thiophosphates stand out due to their high ionic conductivity and room‐temperature processability. However battery rate performance still suffers from increased impedance attributed to the interfacial reactions between thiophosphate electrolyte and oxide electrodes. Stabilizing the interfaces with a protective coating layer has been proposed as a solution to the interfacial problem, but it is rare for a material to simultaneously exhibit fast ionic conductivity and chemical stability at battery interfaces. Here, we propose a double-layer coating design comprising a sulfide-based layer adjacent to the thiophosphate electrolyte accompanied by a layer that is stable against the oxide cathode. Based on a high-throughput thermodynamic stability screen and active learning molecular dynamics simulations, we identify several sulfide + halide couples that potentially outperform the known coating materials in interfacial stability as well as ionic conductivity. Several halides we identify have been recently identified as novel solid electrolyte candidates. We highlight the integration of room-temperature fast ionic conductors Li5B7S13 (137 mS cm−1), Li7Y7Zr9S32 (6.5 mS cm−1), and Li(TiS2)2 (0.0008 mS cm−1) which potentially reduces interfacial reactivity with minor loss of charge transfer rate through the thiophosphate electrolyte.
