Graphite commonly used cathode material in DIBs, however, suffers from poor compatibility with commercial Li-ion electrolytes graphite anodes, making it difficult directly utilize the well-established infrastructure batteries. Herein, we report small aromatic amine molecule 4,4′,4″-tris(diphenylamino)triphenylamine (N4) functioning compatible anion host EC-containing electrolyte. With an average discharge voltage of 3.6 V (vs. Li+/Li), N4 electrode delivers reversible specific capacity 108 mAh/g, which is much higher than 29 mAh/g at same condition. The high retention 91.3% was achieved after 500 cycles 1 A/g. also exhibited good rate performance. Via different characterization techniques like Fourier transform infrared spectroscopy X-ray photoelectron spectroscopy, mechanism revealed conversion between quaternary cations, accompanied by PF6− (de-)insertion. As consequences, assembled N4||graphite DIB w showed 90 within 1.5–4.1 V, cycling stability 98% 40 cycles. Decent performance well. This work provides new insights into designing affordable DIBs.

Combined solid electrolytes address cathode-anode compatibility in all-solid-state Li-ion batteries (ASSLBs), yet interface stability and ion transport mechanisms between different remain unclear. Herein, we investigate Li6PS5Cl (LPSC), Li3InCl6 (LIC), Li1.75ZrO0.5Cl4.75 (LZOC) composite through electrochemical analysis operando X-ray photoelectron spectroscopy. Our results reveal that the electrostatic potential difference LPSC LIC inhibits Li+ migration, leading to decomposition of into InCl3 LiCl, causing battery failure. In contrast, LZOC forms an oxygen-rich interphase with LiCoO2 (LCO), showing better interfacial stability. The promotes diffusion, maintaining even as decomposes, thereby preventing severe degradation LZOC. Therefore, LCO-LZOC cathode exhibits performance than LCO-LIC. This study elucidates basic mechanism reaction diffusion sulfide–halide emphasizes key role electrolyte ASSLBs failure pathways.
