چکیده انگلیسی
All-solid-state lithium batteries based on sulfide solid electrolytes are potential candidates for large-scale energy storage applications. Here, composite cathode with high content of an active material was prepared by a liquid phase process assisted by a dispersant agent to produce a better electrode and electrolyte interface. Li6PS5Cl sulfide electrolyte derived from a solution containing dispersant showed an argyrodite crystal phase with a better distribution of particle size and higher conductivity compared with those without dispersant. Regular distribution of Li6PS5Cl particles in nanometric scale with a spherical shape below 500â¯nm and conductivity of 0.6â¯Ãâ¯10â3â¯Sâ¯cmâ1 (Ïâ¯=â¯1.40â¯gâ¯cmâ3) at room temperature were obtained. Composite cathode was prepared by the dispersion of LiNi1/3Mn1/3Co1/3O2 particles and carbon additive in the Li6PS5Cl-solution containing dispersant agent and subsequent drying at 180â¯Â°C. Bulk-type all-solid-state battery fabricated with the composite cathode containing 89â¯wt% of the active material showed an initial discharge capacity of 110â¯mAâ¯hâ¯gâ1 at 25â¯Â°C and maintained 95% discharge capacity after 15 cycles.
