Conventional synthesis methods, such as solvothermal, hydrothermal, and solid\u2010state, require long synthesis times, the use of solvents and surfactants, and several separation steps. However, the preparation of coated SnS<jats:sub>2<\/jats:sub> composites using liquid media is even more complex, requiring suitable precursors, compatible solvents, and potentially several steps. In the present work, a one\u2010step solid\u2010state method is developed to synthesize SnS<jats:sub>2<\/jats:sub> particles sandwiched in a porous polyacrylonitrile (PAN)\u2010based matrix phase (C\u2013SnS<jats:sub>2<\/jats:sub>) for use as anode active materials for LIBs. The as\u2010synthesized materials exhibit a reversible capacity of 720\u2009mAh\u2009g<jats:sup>\u22121<\/jats:sup> after 100 cycles when tested versus Li\/Li<jats:sup>+<\/jats:sup>. The performance of this SnS<jats:sub>2<\/jats:sub>\u2010based anode active material is compared to that prepared by the solid\u2010state heat treatment of SnS<jats:sub>2<\/jats:sub>, both with and without PAN. The structure, morphology, chemistry, and electrochemical properties of these compounds are established and comprehensively compared to each other. The observed superior cycling stability and rate capability of the sandwich\u2010like C\u2013SnS<jats:sub>2<\/jats:sub> are attributed to its phase purity and its incorporation in a porous, conductive, carbonized PAN matrix.<\/jats:p>","DOI":"10.1002\/smsc.202500192","type":"journal-article","created":{"date-parts":[[2025,7,8]],"date-time":"2025-07-08T01:50:08Z","timestamp":1751939408000},"source":"Crossref","is-referenced-by-count":5,"title":["One\u2010Step
