Nowadays solid‐state lithium metal batteries (SSLMBs) catch researchers’ attention and are considered as the most promising energy storage devices for their high energy density and safety. However, compared to lithium‐ion batteries (LIBs), the low ionic conductivity in solid‐state electrolytes (SSEs) and poor interface contact between SSEs and electrodes counteract some advantages of SSEs. As a result, SSLMBs show high energy density but low critical current density and slow charging speed. Herein, the recent progress and proposed strategies for fast‐charging SSLMBs are reviewed. In the second part of this review, various strategies for improving SSE performance in fast‐charging batteries are comprehensively highlighted. In the third part, various rational structure design schemes benefitting fast‐charging batteries are discussed. Finally, the development of fast‐charging SSLMBs is concluded and prospected. It is believed that the combination of fast‐charging times and SSLMBs is rather competitive for next‐generation, high energy density, high safety, and high charging rate energy storage devices.

Garnet structured solid electrolytes-based lithium metal batteries are the most attractive high energy density electrochemical energy storage candidates for the transportation and grid sectors. Various studies are carried out to address the concerns of lithium garnets as solid electrolytes and improve their electrochemical performance in lithium metal batteries. Interfacial engineering is a widely studied strategy for improving lithium garnet electrolyte-electrode interfacial contact and critical current densities. In the same perspective, microstructural/grain boundary engineering in lithium garnet is an effective strategy for overcoming obstacles and increasing critical current densities (CCD) in lithium metal battery research. The importance of the microstructural properties of the solid electrolyte has been discussed in several investigations. However, a comprehensive overview of the microstructural modification of lithium garnet solid electrolytes and their effect on electrochemical performance is still lacking. This review presents a detailed discussion on the strategies used to modify the microstructure and their impact on performances such as ionic conductivity, interfacial contact, critical current density, dendrite kinetics, etc., of lithium garnet ceramics.

The future state-of-art for energy storage materials is essentially credited to the development of inorganic electrochemical stable solid-state electrolytes (SSEs). All-solid-state lithium batteries (ASSLBs) have been anticipated to be mainly promising a new generation battery technology, owing to the wide range of voltage window, superior safety, and long cyclic performance. Lithium-containing oxide-based garnet (Li7La3Zr2O12) material has become a fascinating potential candidate for ASSLBs as SSEs due to their high ionic conductivity and stability against lithium anode and high capacity cathodes. This review focuses on the computational-guided evolution approaches and screening high-performance garnet materials, showcases all conventional to modern experimental methods, structural studies, and strategies to improve the ionic conductivity of the newly designed garnet SSEs. The panoramic view of chemical instability and developments in interfacial engineering between the cathode/anode and solid-state garnet electrolytes treated via different methods are systematically discussed. The main gaps between lab-scale to large-scale batteries in the integral technology chains, including synthesis technique of solid electrolyte, battery designing, and assembly steps, are identified. Furthermore, we summarize the up-to-date applications of the garnet SSEs and future perspectives to explore the methodologies to develop the ideal garnet solid electrolytes and their commercial applications in ASSLBs.
