Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

Advanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake
