Summary: This study demonstrates a facile and effective strategy to prepare a reduced graphene oxide/carboxymethylcellulose-polyaniline (RGO/CMC-PANI) hybrid film electrode. The hydrogen bonding interaction between -OH of CMC molecules and -NH2 of aniline monomer leads to the ordered growth of PANI on the surface of CMC, which effectively prevents the structural collapse of PANI during charge/discharge cycles. By compounding with RGO, CMC-PANI bridges neighboring RGO sheets and opens gaps between RGO layers, resulting in fast ion channels. Consequently, the RGO/CMC-PANI electrode exhibits excellent electrochemical performance. Moreover, an asymmetric supercapacitor using RGO/CMC-PANI as the anode and Ti3C2Tx as the cathode shows high specific capacitance, energy density, and cycling stability.

Summary: All-solid-state lithium batteries (ASSLBs) are a safe and high-density energy solution to lithium-ion batteries. Argyrodite-based solid-electrolytes (SEs), Li6PS5X (X = Cl, Cl0.5Br0.5 or Br), show promise as candidates for ASSLBs. In this study, the electrochemical behavior of three different argyrodites with Cl- or Br-, or both, as the halogen is systematically investigated, along with their performance in ASSLB cells with LiNi0.6Co0.2Mn0.2O2 as the cathode. SEs containing Br exhibit higher ionic conductivity (>2 mS cm(-1)), critical current density (>=1 mA cm(-2)), and stability up to 5 V versus Li/Li+. Among the three samples, Li6PS5Br shows the best electrochemical performance with high capacity retention and Coulombic efficiency.
