Two-panel figure: (A) crystal-system mix of the COD's no-carbon (inorganic) class by publication year, 1960-2026, annual points + 5-year rolling mean; (B) P1 (space group 1) share of the no-C class, with the 2022 kaolin DFT series, the 2025 generative-model superionic-electrolyte batch (34 P1 cells from one Materials Horizons paper), and the 2026 CdO shear/GSFE supercell deposits annotated.
