density and low safety caused by flammable liquid electrolytes, become the bottleneck restraining the future growth of development. With the concerns of higher energy density (>500 Wh kg -1 ) and a lower probability of dangerous events, all-solid-state lithium batteries (ASSLBs) have become the most anticipated nextgeneration energy storage devices. In particular, solid-state batteries installed with high Li + conductive (1-25 mS cm -1 ) sulfide electrolytes (SSEs) become high-profile future for energy storage systems. [1][2][3] Regardless of superior σ Li+ , the output of sulfide-base solid-state batteries is severely limited by unstable electrode/electrolyte interface, causing high interfacial resistance to originate from various factors, e.g., space charge layer (SCL) and contact loss. Interfacial degeneration is the principal culprit of sub-standard performance, low energy density, and pre-mature failure, and hence, restrains the future growth of sulfide-based ASSLBs. [4,5] Furthermore, degradation of the oxide-based cathode, particularly at high charging cut-off voltage (≥4.5 V), has widely been reported and needs to be addressed for high-energy-density (Wh Kg −1 ) ASSLBs.LCO has incontestable advantages, e.g., high theoretical capacity (274 mAh g −1 ), Li + /e − conductivity, theoretical density, To implement the growing requirement for higher energy density all-solid-state lithium batteries (ASSLBs), further increasing the working voltage of LiCoO 2 (LCO) is a key to breaking through the bottleneck. However, LiCoO 2 severe structural degradation and side reactions at the cathode interface obstruct the development of high-voltage sulfide-based ASSLBs (≥4.5 V). Herein, a nanometric Li 1.175 Nb 0.645 Ti 0.4 O 3 (LNTO) coated LCO cathode where microscopic Ti and Nb segregation at the interface during cycling potentially stabilizes the cathode lattice, and minimizes side reactions, simultaneously, is designed. Advanced transmission electron microscopy reveals that the stable spinel phase minimizes the micro stress at the cathode interface, avoids structure fragmentation, and hence significantly enhances the long-term cyclic stability of LNTO@LCO @ 4.5 V. Moreover, the differential phase contrast scanning transmission electron microscopy (DPC-STEM) visualizes the nano-interlayer LNTO to boost Li + migration at the cathode interface. Electrochemical impedance spectroscopy (EIS) reveals that sulfide-based cells with the LNTO nanolayer effectively reduce the interfacial resistance to 140 Ω compared to LiNbO 3 (235 Ω) over 100 cycles. Therefore, 4.5 V sulfide-based ASSLBs offer gratifying long-cycle stability (0.5 C for 1000 cycles, 88.6%), better specific capacity, and rate performance (179.8 mAh g -1 at 0.1 C, 97 mAh g -1 at 2 C).

Straw returning effectively promotes the soil organic carbon (SOC) pool, but the straw-induced change in SOC quality (C fraction) remains unclear, particularly in saline soil. Here, we investigated how straw returning and soil salinity (low, medium, and high) affect SOC fractions, including easily oxidized and particulate organic C (EOC and POC) and mineral-associated organic C (MOC) at aggregate scales, including macroaggregates (MA), microaggregates (MI), and silt + clay particles. The results revealed that SOC fraction contents in the whole soil decreased with increasing soil salinity, and straw returning increased the total organic C (TOC) in both low-and medium-salinity soils. In low-salinity soil, straw returning induced decreases of 12.1% and 30.6% in MI-associated EOC and POC, respectively, and promoted significant increases of MI-associated MOC, indicating that 'hierarchical aggregation' theory (i.e., single soil particles gradually form clusters, MI and MA) dominated during soil aggregate formation. In medium-salinity soil, straw application increased all SOC fraction contents in MA, and raised the POC/TOC of the whole soil by 56.6%, suggesting that the 'macroaggregate turnover' theory (MI is formed within MA) played a more important role in forming aggregates. Our results demonstrated that low-and medium-salinity soils had different C-increasing strategies under straw returning: MA contributed more to the increased SOC than MI in low-salinity soil, whereas the reverse was true in medium-salinity soil. These findings suggest that higher soil salinity would weaken the C sequestration potential of straw returning, and that targeted measures should be applied to enhance reclamation efficiency.
