Abstract Manganese (Mn)‐based lithium (Li)‐ion batteries with high energy density and low cost have recently attracted considerable attention. One drawback of Mn‐based is the severe capacity attenuation caused by Jahn‐Teller effect, which distorts crystal structure reduces kinetics Li‐ion insertion/extraction in cathodes. In this study, Mn valence state regulated on surface oxide particles oxygen vacancies are introduced to facilitate rapid transport charge storage adding succinonitrile (SN) Because reaction between SN cathode particles, contents 3+ ions increase, leading an improvement kinetic properties cathodes as well a reduction dissolution from By regulating state, Li metal LiMn 2 O 4 or Li‐rich layered show significantly enhanced discharge improved cyclic performance. This study demonstrates that effective strategy for enhancing electrochemical performance cost‐effective method mass production.

Abstract The use of all‐solid‐state lithium metal batteries (ASSLMBs) has garnered significant attention as a promising solution for advanced energy storage systems. By employing non‐flammable solid electrolytes in ASSLMBs, their safety profile is enhanced, and the anode allows higher density compared to traditional lithium‐ion batteries. To fully realize potential solid‐state (SSEs) must meet several requirements. These include high ionic conductivity Li + transference number, smooth interfacial contact between SSEs electrodes, low manufacturing cost, excellent electrochemical stability, effective suppression dendrite formation. This paper delves into essential requirements enable successful implementation ASSLMBs. Additionally, representative state‐of‐the‐art examples developed past 5 years, showcasing latest advancements SSE materials highlighting unique properties are discussed. Finally, provides an outlook on achieving balanced improved addressing failure mechanisms solutions, critical challenges such reversibility plating/stripping thermal runaway, characterization techniques, composite SSEs, computational studies, ASS lithium–sulfur lithium–oxygen With this consideration, ASSLMBs can be realized.
