However, conventional activation methods using potassium and sodium hydroxides or carbonates suffer from low yields (&lt;20%) and poor control over porosity and composition especially when high SSAs are targeted (&gt;2000 m<jats:sup>2</jats:sup> g<jats:sup>−1</jats:sup>) because nanopores are typically created by etching. Herein, a non‐etching activation strategy is demonstrated using cesium salts of low‐cost carboxylic acids as the sole precursor in producing porous carbons with yields of up to 25% and SSAs reaching 3008 m<jats:sup>2</jats:sup> g<jats:sup>−1</jats:sup>. The pore size and oxygen content can be adjusted by tuning the synthesis temperature or changing the molecular precursor. Mechanistic investigation unravels the non‐classical role of cesium as an activating agent. The cesium compounds that form in situ, including carbonates, oxides, and metallic cesium, have extremely low work function enabling electron injection into organic/carbonaceous framework, promoting condensation, and intercalation of cesium ions into graphitic stacks forming slit pores. The resulting porous carbons deliver a high capacity of 252 mAh g<jats:sup>−1</jats:sup> (567 F g<jats:sup>−1</jats:sup>) and durability of 100 000 cycles as cathodes of Zn‐ion capacitors, showing their potential for electrochemical energy storage.</jats:p>"}],"doi":"10.1002/adma.202311655","publication_status":"published","article_number":"2311655","issue":"18","user_id":"98120","publication":"Advanced Materials","publisher":"Wiley","citation":{"ama":"Li J, Xu Y, Li P, et al.
