AB  - Solid-state batteries (SSBs) utilizing halide solid electro-lytes  (SE)  have  garnered  attention  due  to  their  enhanced  stability when paired with oxide-based cathode active materials. However, the dynamic interparticle contact during cycling in SSBs poses challenges to their stability and performance. To mitigate this problem, in this study, we present a one-pot, aqueous synthesis of composites that integrate ion conductivity, electron conductivity, and mechanical sta-bility into a single material. The developed composites consist of a halide SE, lithium indium chloride (Li3InCl6), and a conductive polymer (CP),    poly(3,4-ethylendioxythiophene)/poly(styrene    sulfonate) (PEDOT:PSS).  The  successful  synthesis  was  verified  using spectroscopic,  thermal,  scattering,  and  microscopy  methods,  with Kelvin  Probe  Force  Microscopy  (KPFM)  demonstrating  the distribution of PEDOT:PSS at thegrain boundaries between Li3InCl6particles.  Upon  incorporating  our  composite  material  with  lithium nickel manganese cobalt oxide (NMC) cathode active material (CAM) as  catholyte,  an  increase  in  the  partial  electronic  transport  was observed with increasing CP content. A direct correlation between the partial electronic transport of the catholytes and the initial discharge capacities was demonstrated. This study lays the groundwork for the preparation  of  multi-functional  catholytes  under  more  sustainable conditions,  without  the  need  for  organic  solvents,  extremely  high temperatures, or special environments
