Tin-based chalcogenides have attracted tremendous attention as an anode material for sodium storage owing to their unique structure and high theoretical capacity. Unfortunately, the large volume change and poor conductivity lead to sluggish reaction kinetics and poor cycling performance. Herein, SnS_(0.5)Se_(0.5)nanoparticles coupled with N/S/Se triple-doped carbon nanofibers(SnS_(0.5)Se_(0.5)@NSSe-C) are designed and synthesized through electrospinning and annealing process. Benefiting from the synergistic effects of SnS_(0.5)Se_(0.5)and NSSe-C, the SnS_(0.5)Se_(0.5)@NSSe-C nanofibers exhibit a high reversible capacity and ultralong cycle life at higher current density for sodium-ion batteries. Furthermore, the sodium storage mechanism and electrochemical reaction kinetics of the SnS_(0.5)Se_(0.5)@NSSe-C composite are characterized by the in-situ measurements. The theoretical calculations further reveal the structural advantages of SnS_(0.5)Se_(0.5)@NSSeC composite, which exhibits a high adsorption energy of Na+. This work can provide a novel idea for the synthesis of ternary tin-based chalcogenides and is beneficial for the investigation of their reaction kinetics.

Sodium-ion batteries （SIBs） have been increasingly attracting attention as a sustainable alternative to lithium-ion batteries for scalable energy storage. The key to advanced SIBs relies heavily upon the development of reliable anodes. In this respect, Bi2S3 has been extensively investigated because of its high capacity, tailorable morpholog, and low cost However, the common practices of incorporating carbon species to enhance the electrical conductivity and accommodate the volume change of Bi2S3 anodes so as to boost their durability for Na storage have met with limited success. Herein, we report a simple method to realize the encapsulation of Bi2S3 nanorods within three-dimensional, nitrogen-doped graphene （3DNG） frameworks, targeting flexible and active composite anodes for SIBs. The Bi2S3/ 3DNG composites displayed outstanding Na storage behavior with a high reversible capacity （649 mAh·g^-1 at 62.5 mA·g^-1） and favorable durability （307 and 200 mAh·g^-1 after 100 cycles at 125 and 312.5 mA·g^-1, respectively）. In-depth characterization by in situ X-ray diffraction revealed that the intriguing Na storage process of Bi2Sa was based upon a reversible reaction. Furthermore, a full, flexible SIB cell with Na0.4MnO2 cathode and as-prepared composite anode was successfully assembled, and holds a great promise for next-generation, wearable energy storage applications.

The booming of wearable electronics has nourished the progress on developing multifunctional energy storage systems with versatile flexibility, which enable the continuous and steady power supply even under various deformed states. In this sense, the synergy of flexible energy and electronic devices to construct integrative wearable microsystems is meaningful but remains quite challenging by far. Herein, we devise an innovative supercapacitor/sensor integrative wearable device that is based upon our designed vanadium nitride-graphene (VN-G) architectures. Flexible quasi-solid-state VN-G supercapacitor with ultralight and binder-free features deliver a specific capacitance of^53 F·g^-1 with good cycle stability. On the other hand, VN-G derived pressure sensors fabricated throughout a spray-printing process also manifest favorably high sensitivity (40 kPa^-1 at the range of 2-10 kPa), fast response time (~130 ms), perfect skin conformability, and outstanding stability under static and dynamic pressure conditions. In tum, their complementary unity into a self-powered wearable sensor enables the precise detecti on of physiological motions ranging from pulse rate to phonetic recognition, holding promise for in-practical health monitoring applications.

A layered perovskite oxide Y0.8Ca0.2BaCoFeO5＋δ（YCBCF） was synthesized as a novel cathode material for intermedi-ate-temperature solid oxide fuel cells （IT-SOFCs） by citric acid-nitrates self-propagating combustion method. The phase and micro-structure of YCBCF were investigated by X-ray diffraction （XRD） and scanning electron microscopy （SEM）, respectively. The aver-age thermal expansion coefficient （TEC） of YCBCF was 14.6×10–6 K–1, which was close to other materials of SOFC at the range of RT–1000 oC. An open-circuit potential of 0.75 V and a maximum output power density of 426 mW/cm2 were obtained at 650 oC in a Sm0.2Ce0.8O1.9 （SDC）-based anode-supported SOFC by using humidified （~3%H2O） hydrogen as fuel and static air as oxidant. The results indicated that the YCBCF was a promising cathode candidate for IT-SOFCs.
