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.

“…30,31 Two pairs of obvious redox peaks at around 1.17/0.94 V are attributed to the transformation between LiH/Li 2 O and LiOH, while the redox peak at around 2.37/1.86 V can be ascribed to the redox of Mg 2+ /Mg x+ (0 o x o 2, to be discussed later). 32 The second and third cycle CV curves overlap well, suggesting a reversible electrochemical reaction.

“…Graphite is extensively used as an anode material in recent commercial LIBs. However, the formation of the intercalation compound LiC 6 results in a low theoretical capacity of 372 mAh g −1 , limiting the further improvement of LIBs’ performance [7–9] . Consequently, the search for candidates for emerging anodes with a high and stable capacity has become extremely urgent.…”

Two‐dimensional metal‐organic frameworks (2D MOFs) with more exposed active sites and stable structures are auspicious electrode materials for high‐performance lithium‐ion batteries (LIBs). In the current work, ultrasonic treatment was used to prepare two‐dimensional CoNi‐BDC ultrathin nanosheets (N‐CoNi‐BDC) by coordinating Ni2+, Co2+, and benzenedicarboxylic acid (BDC). The N‐CoNi‐BDC was used as the anode of LIBs, demonstrating an exceptional reversible storage capacity of 1358 mAh g−1 after 200 cycles at 0.1 A g−1. In addition, a charging capacity of 757 mAh g−1 was observed at a high current density of 1 A g−1 without observable capacity degradation up to 300 cycles. The superior behavior of N‐CoNi‐BDC was attributed to its distinct morphology of ultrathin nanosheets with more exposed active sites and stable structures. Ex‐situ FTIR and XPS results revealed that the benzene ring, carboxylate, and Ni2+ in N‐CoNi‐BDC were the active parts of lithium‐ion storage.
