“…There are significant challenges facing the DIB anode materials, such as the limited specific capacity and their sluggish reaction kinetics, which relate to the mismatch with the cathode side, that need to be overcome [ 56 , 57 ]. To address these issues, compositing active materials with highly conductive carbon, designing porous structures, and building nanostructural crystalline are reliable strategies for boosting the electrochemical performance of anode materials [ 39 , 58 , 59 ].…”

There has been increasing demand for high-energy density and long-cycle life rechargeable batteries to satisfy the ever-growing requirements for next-generation energy storage systems. Among all available candidates, dual-ion batteries (DIBs) have drawn tremendous attention in the past few years from both academic and industrial battery communities because of their fascinating advantages of high working voltage, excellent safety, and environmental friendliness. However, the dynamic imbalance between the electrodes and the mismatch of traditional electrolyte systems remain elusive. To fully employ the advantages of DIBs, the overall optimization of anode materials, cathode materials, and compatible electrolyte systems is urgently needed. Here, we review the development history and the reaction mechanisms involved in DIBs. Afterward, the optimization strategies toward DIB materials and electrolytes are highlighted. In addition, their energy-related applications are also provided. Lastly, the research challenges and possible development directions of DIBs are outlined.

Silicon (Si) is considered the most promising anode material for the next generation of lithium‐ion batteries (LIBs) because of its high theoretical specific capacity and abundant reserves. However, the volume expansion of silicon in the cycling process causes the destruction of the electrode structure and irreversible capacity loss. As a result, the commercial application of silicon materials is greatly hindered. In recent years, siloxane‐based organosilicon materials have been widely used in silicon anode of LIBs because of their unique structure and physical and chemical properties, and have shown excellent electrochemical properties. The comprehensive achievement of siloxanes in silicon‐based LIBs can be understood better through a systematic summary, which is necessary to guide the design of electrodes and achieve better electrochemical performance. This paper systematically introduces the unique advantages of siloxane materials in electrode, surface/interface modification, binder, and electrolyte. The challenges and future directions for siloxane materials are presented to enhance their performance and expand their application in silicon‐based LIBs.

“…The development of advanced energy storage technologies is of significance in realizing large‐scale utilization of sustainable energy, especially with the recent rising concerns about supply issues of fossil fuels and their environmental problems 1–4 . Different from lithium‐ion batteries (LIBs) that need unevenly distributed lithium resources, sodium‐ion batteries (SIBs) with abundant sodium natural reserves are viewed as promising alternative energy storage devices 5–8 .…”

Carbon nitrides with two‐dimensional layered structures and high theoretical capacities are attractive as anode materials for sodium‐ion batteries while their low crystallinity and insufficient structural stability strongly restrict their practical applications. Coupling carbon nitrides with conductive carbon may relieve these issues. However, little is known about the influence of nitrogen (N) configurations on the interactions between carbon and C3N4, which is fundamentally critical for guiding the precise design of advanced C3N4‐related electrodes. Herein, highly crystalline C3N4 (poly (triazine imide), PTI) based all‐carbon composites were developed by molten salt strategy. More importantly, the vital role of pyrrolic‐N for enhancing charge transfer and boosting Na+ storage of C3N4‐based composites, which was confirmed by both theoretical and experimental evidence, was spot‐highlighted for the first time. By elaborately controlling the salt composition, the composite with high pyrrolic‐N and minimized graphitic‐N content was obtained. Profiting from the formation of highly crystalline PTI and electrochemically favorable pyrrolic‐N configurations, the composite delivered an unusual reverse growth and record‐level cycling stability even after 5000 cycles along with high reversible capacity and outstanding full‐cell capacity retention. This work broadens the energy storage applications of C3N4 and provides new prospects for the design of advanced all‐carbon electrodes.
