Single-step laser-printed integrated sulfur cathode toward high-performance lithium-sulfur batteries.

ABSTRACT: Lithium-sulfur batteries are expected to supersede existing lithium-ion batteries due to the high theoretical energy density of sulfur cathodes (positive electrodes). Unfortunately, inefficient redox reactions and the "shuttle effect" hinder their commercial development. Assembling high-performance nanostructured sulfur host materials into a sulfur cathode presents a viable solution. However, fabricating host materials and preparing sulfur cathodes involve complicated, multistep, and labor-intensive processes under varying temperatures and conditions, raising concerns about efficiency and cost in practical production. Herein, we propose a single-step laser printing strategy to prepare high-performance integrated sulfur cathodes. During the high-throughput laser-pulse irradiation process, t
