“…Among these different battery types, lithium ion batteries (LIB) are the most advanced and already commercialized [6,7] . Lithium ion batteries can be used for different purposes, from electric vehicles to microdevices for portable objects, depending on the component chosen (different cathodes based on the capacity and lithium insertion voltage, different electrolytes based on the stability window) [8,9] …”

All‐solid‐state lithium ion batteries (LIB) are currently the most promising technology for next generation electrochemical energy storage. Many efforts have been devoted in the past years to improve performance and safety of these devices. Nevertheless, issues regarding chemical and mechanical stability of the different components still hinder substantial improvements. Pulsed laser deposition (PLD) has proved to be an outstanding technique for the deposition of thin films of materials of interest for the fabrication of LIB. Thanks to its versatility and possible fine tuning of the thin film properties, PLD promises to be a very powerful tool for the fabrication of model systems which would allow to study in detail material properties and mechanisms contributing to LIB degradation. Nevertheless, PLD presents difficulties in the deposition of LIB components, mainly due to the presence of elements with large difference of atomic mass in their chemical composition. In this review, we report the main challenges and solution strategies used for the deposition through PLD of complex oxides thin films for LIB.

All‐solid‐state Li batteries (ASSLBs) are attracting increasing attentions due to their improved safety and high energy density compared with conventional liquid electrolyte‐based Li‐ion batteries (LIBs). ASSLBs based on sulfide solid‐state electrolytes (SEs) is one of the most popular categories, because sulfide SEs have a very competitive ionic conductivity (up to over 10−2 S cm−1 at room temperature), medium mechanical stiffness, decent contact with electrode materials, and negligible grain boundary resistance. However, interface problems between electrode materials and sulfide SEs seriously plague the development of high‐performance sulfide‐based ASSLBs. In‐depth understandings on the electrode interface problems are pivotal to propose and explore effective strategies to alleviate those issues. In recent years, diverse advanced characterization techniques have been developed, which deepen insights into the problematic interface from physical, chemical, electrochemical, and mechanochemical perspectives. Herein, electrode interfaces and their fundamental knowledge in sulfide‐based ASSLBs are first clarified. Second, various emerging characterizations are overviewed to illustrate the interfacial issues on both oxide cathode/sulfide SE and Li anode/sulfide SE interfaces. Meanwhile, advantages and disadvantages of each characterization techniques are explicated. Finally, an outlook of advanced characterizations that are specifically adapted for interface analysis in sulfide‐based ASSLBs is proposed.

“…(iv) The space charge layer is an electrochemical double layer generated at the interface between the electrode and the electrolyte, which is formed as a result of the charge diffusion motion and drift motion that is caused by the internal electric field. The space charge layer usually leads to local charge depletion or enrichment, affects the transport of lithium ions, and enhances the ionic state in the solid-solid dispersion with poor ionic conductivity [20]. However, for SE with high conductivity, it may establish an interfacial barrier for lithium ions transport, and thus hinders ionic conduction.…”

In the past few years, the all-solid lithium battery has attracted worldwide attentions, the ionic conductivity of some all-solid lithiumion batteries has reached 10 −3 -10 −2 S/cm, indicating that the transport of lithium ions in solid electrolytes is no longer a major problem. However, some interface issues become research hotspots. Examples of these interfacial issues include the electrochemical decomposition reaction at the electrode-electrolyte interface; the low effective contact area between the solid electrolyte and the electrode etc. In order to solve the issues, researchers have pursued many different approaches. The addition of a buffer layer between the electrode and the solid electrolyte has been at the center of this endeavor. In this review paper, we provide a systematic summarization of the problems on the electrode-solid electrolyte interface and detailed reflection on the latest works of buffer-based therapies, and the review will end with a personal perspective on the improvement of buffer-based therapies.
