“…The construction of hierarchical porous nanostructures is a common method to address this problem. For instance, Wei et al [ 18 ] fabricated hierarchical porous NiFe 2 O 4 nanosheets by using waste bagasse as a template. The reversible capacity of this anode remained at 1229.1 and 989.6 mAh g −1 at 200 and 500 mA g −1 after 300 cycles, respectively.…”

“…Hierarchical porous nanostructures not only provide sufficient buffer space in the electrode to accommodate drastic volume changes but also facilitate electrolyte diffusion and electron transport [ 19 , 20 ]. However, the general process of constructing hierarchical porosity requires complex crafts, for instance, the template method, which is usually further treated by acidic erosion and/or heat treatment [ 18 ]. These complex technologies, including environmentally unfriendly and energy-intensive processes, limit the further application of NiFe 2 O 4 as LIB anodes.…”

As high-capacity anode materials, spinel NiFe2O4 aroused extensive attention due to its natural abundance and safe working voltage. For widespread commercialization, some drawbacks, such as rapid capacity fading and poor reversibility due to large volume variation and inferior conductivity, urgently require amelioration. In this work, NiFe2O4/NiO composites with a dual-network structure were fabricated by a simple dealloying method. Benefiting from the dual-network structure and composed of nanosheet networks and ligament-pore networks, this material provides sufficient space for volume expansion and is able to boost the rapid transfer of electrons and Li ions. As a result, the material exhibits excellent electrochemical performance, retaining 756.9 mAh g−1 at 200 mA g−1 after cycling for 100 cycles and retaining 641.1 mAh g−1 after 1000 cycles at 500 mA g−1. This work provides a facile way to prepare a novel dual-network structured spinel oxide material, which can promote the development of oxide anodes and also dealloying techniques in broad fields.
