a Digital photos of POEs with millimeter thickness (and a Canadian dime with 1.20 mm thickness) and their corresponding (b–d) cross-section SEM images: b ~50 mg cm−2, c ~100 mg cm−2, d ~150 mg cm−2. Scale bars, 200 μm. e Charge-discharge profiles of thick POEs with different mass loadings. f Plot of areal capacity against mass loading. g Cycling performance of thick POEs (mass loadings: ~100 mg cm−2 and ~150 mg cm−2) under low N/P ratio and lean electrolyte. h Capacity-rate profiles of batteries based on POEs with different AM fraction (80%, 90%, and 95%). i Capacity retention and CE values of 90%-, and 95%-P-PTCDA cells during long cycling. j Comparison of POEs with reported battery electrodes in terms of mass loadings, AM fraction, and areal capacity. k Gravimetric/areal/volumetric energy density and cost analysis of cells based on different POEs.
