Abstract Silicon is a promising candidate for replacing graphite in anodes advanced Li‐ion batteries due to its high theoretical gravimetric energy density. However, silicon as an active anode material suffers from significant volume changes upon lithiation/delithiation, causing fast capacity fading. The performance of depends on the polymeric binders used, which form well‐bound Si particles matrices that accommodate strains developed during their repeated lithiation, thus maintaining integrity.

Herein, we report a carbon-fiber-based freestanding electrode for NaVPO 4 F cathodes in sodium-ion batteries. The replacement of conventional aluminium foil with carbon fiber mat-based current collector results significant improvement capacity at high rates and charge-discharge cycle stability. Petroleum-pitch (P-Pitch) has dual functions. P-pitch is used as binder to bind particles onto the mat, which helps eliminate typical organic binders. At same time, P-Pitch acts conducting precursor...
