Large‐scale synthesis of nanostructured carbon‐Ti4O7 hollow particles as efficient sulfur host materials for multilayer Li‐S pouch cells

Polysulfides ball: A scalable synthesis of carbon coated Ti4O7 hollow nanoparticles using spherical polymer electrolyte brush as soft template has been developed as efficient sulfur host for multilayer lithium-sulfur pouch cells. The nanoparticles provide strong chemical adsorption to polysulfides and endow a stable cycling with a high-capacity retention of 83.7 % after 100 cycles at 0.1 C.
