Co<sub>3</sub>O<sub>4</sub>-Induced Na<sub>2</sub>CO<sub>3</sub>-Rich SEI Film on an FeNCN Electrode with Promoted Loading and High-Rate Na-Storage Performance

Iron carbodiimide (FeNCN) often suffers from unstable interfacial structure with an unexpected failure of Na-ion storage performance. In this work, Co<sub>3</sub>O<sub>4</sub> particles were deposited on the surface of FeNCN. This Co<sub>3</sub>O<sub>4</sub> nanolayer led to the formation of a Na<sub>2</sub>CO<sub>3</sub>-rich inorganic component SEI film to enhance the stability of a promoted-loading FeNCN electrode interface with fast Na<sup>+</sup> migration pathway. Benefitting from this strategy, the FeNCN electrode could present a capacity retention rate of 99.95% per cycle after 1500 cycles at 1 A g<sup>-1</sup>. The design of interfacial structure in a promoted-loading electrode could be a reference for stable and high-rate performance of carbodiimide-based materials.

Abstract

Iron carbodiimide (FeNCN) often suffers from unstable interfacial structure with an unexpected failure of Na-ion storage performance. In this work, Co<sub>3</sub>O<sub>4</sub> particles were deposited on the surface of FeNCN. This Co<sub>3</sub>O<sub>4</sub> nanolayer led to the formation of a Na<sub>2</sub>CO<sub>3</sub>-rich inorganic component SEI film to enhance the stability of a promoted-loading FeNCN electrode interface with fast Na<sup>+</sup> migration pathway. Benefitting from this strategy, the FeNCN electrode could present a capacity retention rate of 99.95% per cycle after 1500 cycles at 1 A g<sup>-1</sup>. The design of interfacial structure in a promoted-loading electrode could be a reference for stable and high-rate performance of carbodiimide-based materials.
