摘要	The interaction between electrode materials and charge carriers is one of the central issues dominating underlying energy storage mechanisms. To address the notoriously significant volume changes accompanying intercalation or formation of alloy/compounds, we aim to introduce and utilize a weak, reversible FeN interaction during the (de)intercalation of ammonium ions (NH4+) within iron(III) hexacyanoferrate (FeHCF), inspired by manipulating the electrostatic adsorption between N and Fe in the early stages of ammonia synthesis (Bosch-Harber Process, Chemical Engineering) and steel nitriding processes (Metal Industry). Such strategy of switching well-balanced FeN interaction is confirmed in between the nitrogen of ammonium ions and high-spin Fe in FeHCF, as observed by using X-ray absorption spectroscopy. The resulting material provided an extremely stable energy storage (58 mAh g1 after 10 000 cycles at current density of 1 A g1) as well as high-rate performance (23.6 mAh g1 at current density of 10 A g1). 2022 Zhengzhou University.
