“…Due to the enlargement of interspace and improved electronic conductivity as well as mechanical property, the hierarchical nitrogen-doped MoS 2 /SiOC composite achieved a facile reversible cycle of Na ions during the operation of the battery, namely 540.7 mAh/g of reversible capacity and almost 100% of capacity retention, also including excellent rate capability at 10 A/g. Putra et al [507] studied SiOC-graphene composites pyrolyzed from silicone oil and demonstrated their excellent performance. They also studied the effect of fluorinated ethylene carbonate in the electrolyte on the electrochemical performance.…”

Since the 1960s, a new class of Si-based advanced ceramics called polymer-derived ceramics (PDCs) has been widely reported because of their unique capabilities to produce various ceramic materials (e.g., ceramic fibers, ceramic matrix composites, foams, films, and coatings) and their versatile applications. Particularly, due to their promising structural and functional properties for energy conversion and storage, the applications of PDCs in these fields have attracted much attention in recent years. This review highlights the recent progress in the PDC field with the focus on energy conversion and storage applications. Firstly, a brief introduction of the Si-based polymer-derived ceramics in terms of synthesis, processing, and microstructure characterization is provided, followed by a summary of PDCs used in energy conversion systems (mainly in gas turbine engines), including fundamentals and material issues, ceramic matrix composites, ceramic fibers, thermal and environmental barrier coatings, as well as high-temperature sensors. Subsequently, applications of PDCs in the field of energy storage are reviewed with a strong focus on anode materials for lithium and sodium ion batteries. The possible applications of the PDCs in Li-S batteries, supercapacitors, and fuel cells are discussed as well. Finally, a summary of the reported applications and perspectives for future research with PDCs are presented.

“…[24][25][26] The O 1s spectrum was divided into four peaks located at 530.5, 531.6, 533.0, and 533.0 eV (Figure 2C), corresponding to the COOH bond, C─OH bond, C═O/O─Si bond, and Si─O─Si bond, respectively. [27,28] The presence of oxygen can not only enhance the wettability to reduce the inert surface area, but also serve as electrochemical active sites. [22,29] As shown in Figure 2D, the Si 2p spectrum can be deconvoluted into SiO 2 C 2 (101.8 eV), SiO 3 C (102.7 eV) and SiO 4 (103.5 eV), respectively, [28,30] suggesting that the Si could be coupled with carbon matrix through oxygen atoms.…”

Hierarchical Carbon Nanosheet Assembly with SiO_x Incorporation and Nitrogen Doping Achieves Enhanced Lithium Ion Storage Performance

Lithium ion batteries (LIBs) have dominated the markets of portable electronics due to the merits of a low self‐discharge rate, high voltage platform, environmental friendliness, and portability. However, the limited theoretical capacity of the current commercial anode material causes unsatisfied energy density of LIBs, which falls behind the ever‐increasing demands of society. Herein, a hierarchical porous carbon nanosheet assembly is successfully constructed with simultaneous SiOx incorporation and nitrogen doping (denoted as HPCNA‐(N, Si)) through a supramolecular assembly–based one‐pot strategy followed by a calcination process. Benefitting from the unique morphology, highly porous feature, and the synergy of SiOx incorporation and nitrogen doping, the HPCNA‐(N, Si) exhibits largely enhanced Li+ storage performance when evaluated as anode material for LIBs. Specifically, it can deliver a high specific capacity of 583.0 mA h g−1 at 500 mA g−1 with a stable cycling capability (700 cycles with an average attenuation rate of 0.32% at 1000 mA g−1). The possible origins of the promising Li+ storage behavior for HPCNA‐(N, Si) are unraveled based on the cyclic voltammetry (CV) curves, where a fair capacitive contribution of 63.6% at 0.9 mV s−1 could imply fast ion transfer kinetics for superior rate and cycling performance.

“…Generally, the low value of CE is attributed to the SEI layer formation. 40 The second, third, and fourth cycles exhibited significantly improved CE values of 95%, 96%, and 99.8%, respectively. The discharge and charge profiles of the S:MoP-5 electrode show sloping behavior which reveals the capacitive storage of sodium.…”

Summary The electrode materials with high rate capability are required to meet the ever‐demanding performance of rechargeable batteries. Herein, sulfur‐doped molybdenum phosphide (S:MoP) is prepared using (thio)urea‐phosphate‐assisted strategy and investigated as anode material for Li‐ and Na‐ion batteries. This approach provides the self‐doping of sulfur in MoP lattice that stabilizes the least stable oxidation state of phosphorus (P−3) of MoP through Mo/P–S bonds, enhances the electronic conductivity, and maximizes the Li‐/Na ions adsorption sites. The phase pure hexagonal S:MoP is obtained at 700°C (S:MoP‐7) and the complete reduction of phosphate is confirmed through X‐ray diffraction as well as X‐ray absorption spectroscopy. The presence of chemical bonding of Mo‐P/S and P‐S is detected by X‐ray photoelectron spectroscopy. S:MoP‐7 anode shows excellent rate capability where it delivers 112 mAh g−1 capacity at 12.8 C rate and high stability with 436 mAh g−1 capacity at 100th cycle at 0.1 C rate when tested in lithium‐ion batteries. The S:MoP‐7 as an anode exhibits high rate capability in sodium‐ion batteries and delivers 133 mAh g−1 capacity at 6.4 C rate and 307 mAh g−1 at 0.1 C rate at the 100th cycle. The high performance of the S:MoP‐7 electrode is attributed to the interconnected porous network, increased active sites for Li‐ and Na‐ions via S‐doping, and reduced charge transfer resistance as observed using electrochemical impedance spectroscopy.
