Physically/ chemically stable solid electrolyte/ lithium anode interface for cheaper, high-performance lithium-sulfur batteries

https://techxplore.com/news/2026-04-scientists-boost-solid-state-battery.html

"lithium anode expands/ contracts causing pulling away from solid electrolyte creating voids block ion flow/ dead non-conductive layer, overcome introducing iodine or bromine halide elements into sulfur cathode/ solid electrolyte triggering bridge-forming reaction... new layer glues battery components together at molecular level... >400 Wh/kg. energy density maintaining 80% capacity after 450 cycles at room temperature... no flammable liquid electrolytes/ cobalt... automatic halide segregation"
