Heterointerface Engineered Core-Shell Fe₂O₃@TiO₂ for High-Performance Lithium-Ion Storage.

ABSTRACT: The rational design of the heterogeneous interfaces enables precise adjustment of the electronic structure and optimization of the kinetics for electron/ion migration in energy storage materials. In this work, the built-in electric field is introduced to the iron-based anode material (Fe₂O₃@TiO₂) through the well-designed heterostructure. This model serves as an ideal platform for comprehending the atomic-level optimization of electron transfer in advanced lithium-ion batteries (LIBs). As a result, the core-shell Fe₂O₃@TiO₂ delivers a remarkable discharge capacity of 1342 mAh g^-1 and an extraordinary capacity retention of 82.7% at 0.1 A g^-1 after 300 cycles. Fe₂O₃@TiO₂ s
