“…Note that the peaks at 32.8°, 46.3°, 47.0° and 48.4°, match well with the lattice planes of (011), (112), (202) and (211) of FeP (JCPDS card No. 65‐2595) . Combined with the TEM results and XRD patterns, the highly active phosphorus is indeed introduced into Fe 3 O 4 matrix, and partial oxides are converted into FeP.…”

In terms of Fe 3 O 4 -based anodes, enormous academic progress has been achieved over the past two decades; however, even with excellent half-cell performance, the relatively high lithiation potential and unsatisfactory initial coulombic efficiency (ICE) represent two major barriers to their commercial application, at present. We propose partially phosphorized Fe 3 O 4 (PÀ Fe 3 O 4 ) with interior void spaces induced by phosphorization to enhance the Li + storage property of Fe 3 O 4 -based anodes. PÀ Fe 3 O 4 anodes offer a much higher capacity at low potential compared with bare Fe 3 O 4 electrodes. Additionally, the welldesigned nanostructure with preferable specific surface area prevents the initial irreversible lithium loss, which contributes to a brilliant ICE (80.8 % at 100 mA g À 1 ). Moreover, in-situ X-ray diffraction proves that the formation of the Li x Fe 3 O 4 phase results from an initial intercalation process. In particular, the output voltage and energy density of PÀ Fe 3 O 4 full-cells are much greater than those of Fe 3 O 4 full-cells. In this work, the PÀ Fe 3 O 4 full-cell exhibits a capacity of 680 mAh g À 1 at 200 mA g À 1 as well as an excellent rate capability of 267 mAh g À 1 with a current density up to 1000 mA g À 1 . This study presents a new strategy to enhance Li + storage of Fe 3 O 4 enabling low lithiation/delithiation potential and high ICE, which may offer exciting opportunities toward designing highperformance full-cells with commercial cathodes.

“…Over the last several decades, several classes of materials have emerged as possible conversion anodes for both micro‐ and macrobatteries, such as transition metal oxides, carbides, and sulfides . In particular, metal phosphides have displayed strong performance in both lithium‐ion and sodium‐ion batteries, owing to their high capacity, good electronic conductivity, and naturally abundant constituent elements.…”

Transition metal phosphides are a new class of materials generating interest as alternative negative electrodes in lithium‐ion batteries. However, metal phosphide syntheses remain underdeveloped in terms of simultaneous control over phase composition and 3D nanostructure. Herein, M13 bacteriophage is employed as a biological scaffold to develop 3D nickel phosphide nanofoams with control over a range of phase compositions and structural elements. Virus‐templated Ni5P4 nanofoams are then integrated as thin‐film negative electrodes in lithium‐ion microbatteries, demonstrating a discharge capacity of 677 mAh g–1 (677 mAh cm–3) and an 80% capacity retention over more than 100 cycles. This strong electrochemical performance is attributed to the virus‐templated, nanostructured morphology, which remains electronically conductive throughout cycling, thereby sidestepping the need for conductive additives. When accounting for the mass of additional binder materials, virus‐templated Ni5P4 nanofoams demonstrate the highest practical capacity reported thus far for Ni5P4 electrodes. Looking forward, this synthesis method is generalizable and can enable precise control over the 3D nanostructure and phase composition in other metal phosphides, such as cobalt and copper.

“…In this way, many other MOF/graphene composites were prepared. 98,99 Other studies also talked about the covalent functionalization of GO for MOF/graphene nanocomposites with improved properties. [100][101][102][103] For example, Kumar et al utilized benzoic acid to covalently functionalize the graphene basal plane, then the carboxylate groups of the modied graphene bonded with metal ions (M 2+ ), followed by metal ions coordinating with the 2,5dioxido-1,4-benzene dicarboxylate (DOBDC) linker to form MOFs (Fig.…”
