In the slurry-coating process for ASSBs, nitrile rubber (NBR) is primarily used as a binder due to its moderate solubility in non-polar solvents, which exhibites minimal chemical reactivity with sulfide SEs. However, the NBR binder, composed of butadiene and acrylonitrile units with differing polarities, exhibits different chemical compatibility depending on the subtle differences in polarity of solvents. Herein, we systematically demonstrate how the chemical compatibility of solvents with the NBR binder influences the performance of ASSBs. Anisole is found to activate the acrylonitrile units, inducing an elongated polymer chain configuration in the binder solution, which gives an opportunity to strongly interact with the solid components of the electrode and the current collector. Consequently, selecting anisole as a solvent for the NBR binder enables the fabrication of a mechanically robust graphite-silicon anode, allowing ASSBs to operate at a lower stacking pressure of 16 MPa. This approach achieves an initial capacity of 480 mAh g<sup>−1</sup>, significantly higher than the 390 mAh g<sup>−1</sup> achieved with the NBR/toluene binder that has less chemical compatibility.

However, these cathodes face critical challenges, including thermal instability and structural degradation at an elevated temperature, which hinder their practical application. This study introduces an advanced surface reconstruction strategy combining a LiScF<sub>4</sub> coating, Sc/F surface co-doping, and a cation-mixing layer to address these issues. The LiScF<sub>4</sub> coating serves as a durable protective barrier, reducing electrolyte decomposition, minimizing transition metal dissolution, and enhancing lithium-ion transport. Sc/F surface co-doping stabilizes lattice oxygen by increasing the energy barrier for oxygen vacancy formation and minimizing oxygen release, thereby suppressing phase transitions and interfacial side reactions. Additionally, the cation-mixing layer improves interfacial stability by alleviating lattice strain and supporting reversible cation migration, ensuring prolonged durability during cycling and under high-temperature conditions. These integrated modifications work synergistically to mitigate various degradation mechanisms, significantly improving the thermal stability, structural integrity, and electrochemical performance of Ni-rich cathodes. This approach offers a viable pathway for incorporating Ni-rich cathodes into advanced lithium-ion batteries, making them well-suited for applications requiring high thermal stability.

Furthermore, weak hydrogen bonds, acting as “sacrificial bonds”, dissipate energy and disperse accumulated stress, improving the material flexibility. Due to the high mechanical stability of the framework, which combines both rigidity and flexibility and the coupling effect at the three interfaces, the movement and separation of electrode components are effectively restrained, significantly enhancing the cycling stability of silicon-graphite anodes.
