  abstract     = {{Interfacial stability issues at the cathode remain a bottleneck to <br>
developing durable and high-power all-solid-state lithium batteries <br>
(ASSLBs). In fact, the presence of conductive carbon in the cathode, <br>
necessary for high capacity and power capability, is believed to <br>
aggravate the stability woes. Thus, it is typically excluded from the <br>
cathode mix. Herein, employing a model functionalized carbon, it is <br>
shown that a small carbon surface oxygen functionality can in situ <br>
engineer a robust carbon–solid electrolyte interphase, which arrests <br>
conductive carbon-mediated degradation of Li<sub>6</sub>PS<sub>5</sub>Cl into reactive polysulfides that degrades the active LiNi<sub>1/3</sub>Mn<sub>1/3</sub>Co<sub>1/3</sub>O<sub>2</sub><br>
 (NMC) cathode. Such interfacial stabilization, as confirmed by ex situ <br>
spectroscopic and in situ impedance analysis, combined with fast charge <br>
transport facilitated by functionalized yet conductive carbon and lowly <br>
resistive cathode interphases, elevates the performance. This is <br>
evidenced by stable cycling at room temperature (22 °C) and elevated <br>
temperatures (60 °C), high rate capability, a Coulombic efficiency of <br>
99.8%, and ≈100% capacity retention after 1000 cycles and &gt;90% <br>
retention over 2000 cycles at 60 °C. Functionalized carbon-mediated in <br>
situ cathode interfacial engineering offers a simple and scalable <br>
approach to designing durable ASSLB cathodes, with the potential for <br>
broader application across various NMC cathodes and compatible solid <br>
electrolytes.}},
