a Effect of the c-IPN cathode on the specific energy of cells (excluding packaging substances) and the specific capacity of electrode active materials (Csp) of NCM811 as a function of the areal-mass-loading (M/A). b Photograph of the double-stacked pouch-type cell (area = 34 × 34 (mm × mm)), in which the c-IPN cathode (C/A = 18 mAh cm–2) was coupled with a Li-metal anode (20 mAh cm–2, negative to positive electrode capacity ratio (N/P) of 1.1) under a limited amount (electrolyte mass/cell capacity (E/C) ratio of 2.5 g Ah–1) of carbonate-based liquid electrolyte). c X-ray microtomography image showing the cross-sectional structure of the double-stacked pouch cell. d Cycling performance of the double-stacked pouch-type cell at a charge/discharge current density of 0.9 mA cm–2/1.8 mA cm–2 and a voltage range of 3.0–4.4 V at 25 °C.
