Summary: In this study, a simple in situ polymerization method of 1,3-dioxolane electrolytes was used to fabricate integrated solid-state lithium batteries. The key to achieving a high-performance battery with excellent interfacial contact among carbon nanotubes (CNTs), active materials, and electrolytes is the in situ polymerization and formation of solid-state dioxolane electrolytes on interconnected CNTs and active materials. These batteries demonstrated high energy density, amazing charge/discharge rate, and long cycle life, thanks to the low resistance of 4.5 omega (-1) and high lithium-ion diffusion efficiency of 2.5x10(-11) cm(2) s(-1).

Summary: Although various strategies exist for manufacturing solid-state polymer lithium batteries (SSPLBs), the in situ polymerization process is the most promising. This process allows for good electrolyte/electrode contact and is compatible with existing lithium-ion battery manufacturing, making scale-up production easier. However, current studies on the in situ polymerization process primarily focus on lab-level coin cells, with limited research on practical pouch cells. This article provides a systematic review of the challenges and design principles of in situ polymerization for fabricating practical pouch SSPLBs, complementing existing reports and offering strategic guidance for SSPLBs applications.

Summary: Due to their high energy density and environmental friendliness, lithium-ion batteries (LIBs) have been widely used in electric vehicles, energy storage systems, and other devices. However, the traditional LIBs with liquid electrolytes (LEs) pose safety hazards. In order to achieve higher safety and energy density, researchers are exploring the use of solid-state electrolytes (SSEs) instead. This review comprehensively summarizes the behaviors, properties, and mechanisms of interfaces in all-solid-state lithium batteries with various sulfide SSEs, as well as recent research progress on characterization methods and designs to stabilize interfaces. Outlooks, challenges, and possible interface engineering strategies are also discussed.

Summary: The demand for portable electronic devices has increased the need for higher energy density in layered LiCoO2 (LCO). However, its practical applications are hindered by the unstable surface structure and side reactions at high voltages (>4.5 V). In this study, a conformal and integral LiNixCoyMn2-x-yO4 spinel coating was designed on the surface of LCO using a sol-gel method, which improved cycle and rate performance and stabilized the cathode-electrolyte interface. The designed spinel coating layer was also well preserved after prolonged cycling, preventing the formation of an electrochemically inert Co3O4 phase and ensuring fast lithium transport kinetics.

Summary: The currently dominant cathode material Li(NixCoyMnz)O-2(NCM, x + y + z = 1) in lithium-ion batteries exhibits higher energy density with increasing nickel content, but it also suffers from stronger interface reactions with the electrolyte and worse safety performance. Single crystal cathode materials have advantages such as fewer grain boundaries, higher density, and suppressed microcracks, leading to reduced interfacial side reactions and improved volumetric energy density and safety performance. In this study, a pulse high-temperature sintering (PHTS) strategy is reported to prepare single-crystal Li(Ni0.9Co0.05Mn0.05)O-2 (SC-NCM90), which shows enhanced tap density and thermal stability compared to spherical NCM90 particles.

Summary: This study investigates the crystal structures of Na3YCl6 and proposes a three-step structure construction method using functional (Y2Cl9)3- groups as building blocks to obtain three new crystal structures in the composition of Na3Y2Cl9. The transport properties, thermostability, and electrochemical window of these structures are studied using first-principles calculation methods. The results show that the principle of designing crystal structures of halides by basic blocks is effective, and the P63-Na3Y2Cl9 structure exhibits outstanding transport properties due to the coherent diffusion connecting two directions. This research will promote the understanding of the transport mechanism in halide-based electrolytes and accelerate the inverse design of inorganic crystal structures based on functional building blocks and special stacking modes.

Summary: A comprehensive evaluation methodology is proposed for silicone-based potted modules to assess their physical and electrical properties as well as the influence of gamma-radiation on the encapsulated interface. The results show that gamma-radiation increases the crosslinking density, hardness, elastic modulus, volume resistivity, dielectric constant, and storage modulus, while decreasing the elongation at break and dielectric loss factor. The tensile strength, breakdown strength, and coefficient of thermal expansion of the interface exhibit complex trends. The partial discharge inception voltage slightly increases due to the unchanged interface bonding state and slightly decreased electric field strength at the tip.

Summary: The pursuit of high-energy-density lithium-ion batteries has led to extensive research on the high-capacity lithium-rich manganese-rich oxide cathode (LRMO). This study investigates the thermal stability of LRMO through in situ X-ray diffraction and full-field transmission X-ray microscopy combined with X-ray absorption near edge structure. The roles of Ni and Mn in affecting the thermal stability of LRMO are uncovered, with Ni acting as a key factor that governs the onset temperature of thermal decomposition. Moreover, incomplete coverage of solid polymer electrolytes over the LRMO particle surface may lead to the deterioration of thermal stability.
