Conventional liquid electrolytes for lithium batteries usually suffer from irreversible decomposition and safety concerns. Solid state electrolytes (SSEs) have been considered as the key for advanced lithium batteries with improved energy density and safety, whereas challenges remain for polymer and inorganic SSEs. Recently, hybrid solid-state electrolytes (HSSEs) that integrate the merits of different electrolyte systems have been under intensive study. Herein, we summarize the recent progress of HSSEs with different compositions and structures. The design principle of each type of HSSEs are discussed, as well as their ionic conducting mechanism, electrochemical performance and effects of compositional/structural control. Finally, challenges and perspectives are provided for the future development of HSSEs and solid-state lithium batteries.

“…An interphase with mixed ionic and electronic conductivity will be chemically formed by the Ti reduction reaction, which will lead to degraded interfacial Li + transport, even mechanical and thermal failure . The application of unstable LLTO and LATP must combine with a stable Li + conductive interlayer to avoid direct contact with Li metal …”

“…Compared to inorganic ceramic electrolytes, solid polymer electrolytes (SPEs) exhibit a lower elasticity modulus to overcome the issue of large interfacial resistance. In recent studies, a polyethylene oxide (PEO)‐based SPE has often been used as an interlayer between the Li metal and ceramic electrolyte system . The PEO interlayer with a thickness of several micrometers can tightly adhere to the ceramic electrolyte and reduce the interfacial resistance.…”

Reducing the Interfacial Resistance in All‐Solid‐State Lithium Batteries Based on Oxide Ceramic Electrolytes

All‐solid‐state lithium batteries (ASSLBs) are regarded as next‐generation advanced energy‐storage devices, owing to their high energy density and safety. The interfacial resistance is a crucial factor affecting the practical application of ASSLBs. ASSLBs based on oxide‐based ceramic electrolytes (OCEs) still exhibit poor electrochemical performance, owing to the large interfacial resistance. Area‐specific resistance values at the interfaces ranging from thousands of ohms to several ohms per square centimeter have been achieved using multiple strategies. This Review summarizes multiple existing advanced strategies used to reduce the interfacial resistance between OCEs and electrodes through interfacial engineering. We also propose some perspectives for the future development of ASSLBs based on OCEs.

Rechargeable lithium‐ion batteries with good electrochemical properties require nanostructured electrode materials, which are usually prepared through complex synthesis processes. Herein, a new facile method is reported for the synthesis of high‐performance electrode materials with a crater‐like morphology through repulsion between positive charges. The produced electrode material does not possess a nanostructure. However, it is capable of rapidly transferring lithium ions and electrons owing to the large contact area with electrolyte and the high concentration sp2‐hybridized carbon coating. LiFePO4 and LiNi1/3Co1/3Mn1/3O2 electrodes prepared by this process achieved high discharge capacities of 165.7 and 199.9 mAh g−1 at 0.1 C, with excellent rate capability of 127.5 and 162.6 mAh g−1 at 10 C, respectively. Although the crater‐type materials might decrease the electrode tap density, they facilitate better electrochemical properties such as high capacity, high power, and fast charging. Furthermore, this new method can be applied trough a sol–gel process for the synthesis of electrode materials to improve their electrochemical characteristics.
