“…The cathode with the PISE binder (PISE-LFP) was cured with the polymer electrolyte layer in situ , while the cathode with the PVDF binder (PVDF-LFP) was stacked with a separate polymer electrolyte layer. Compared to PVDF-LFP/PISE/Li batteries, the PISE-LFP/PISE/Li battery with the integrated cathode/electrolyte structure exhibits a smaller interfacial resistance of ∼200 Ω (Figure S28), in favor of the electrochemical kinetics and ion transportation. ,, Figure e shows the cycling performance of the cells with an LFP loading of 4.5 mg cm –2 (0.76 mAh cm –2 ). After the initial few cycles, the discharge capacity of the integrated PISE-LFP/PISE/Li cell quickly increases from 134.5 to 155.5 mAh g –1 (∼0.7 mAh cm –2 ) and maintains 128.3 mAh g –1 and ∼83% capacity retention after 250 cycles.…”

“…In addition, the interfacial compatibilities among solid components containing electrolytes, active materials, and conductive additives are also critical to the comprehensive performance of LMBs. Unlike liquid electrolytes, which can effectively infiltrate and wet incompletely compact cathodes, solid electrolytes usually show poorer contact, leading to sluggish ion transport and high impedance at the electrolyte/electrode interface, whereas ion-conductive polymer electrolytes with sufficient elasticity and strength are expected to accommodate the volume change of the inorganic active material during cycling and enhance the ion conductivity within the cathodes if used as binders as well. Currently, designing mechanically robust PISEs with high ion conductivities and engineered interfaces in LMBs is still a challenge.…”
