Elastic zirconium-based ceramic fiber products have gain particular interest due to their exceptional hightemperature resistant performance. Nonetheless, commercial high-performance Zr-based fibers are still difficult to acquire which hinders its widely application in thermal insulation scenes. Herein, large-scale fabrication of various Zr-based（ZrO2, ZrSiO4） ceramic fibers were achieved through solution blow spinning technology, which was endowed with merits such as cost-effectiveness, high production efficiency, reduced energy consumption, and exceptional product quality. Through high-temperature sintering to 1000°C, blow spun organic fibers can be converted into Zr-based ceramic fibers with diameters ranging from 0.5 to 2 μm. Optimizing the crystalline structure of these fibers through high-temperature pyrolysis process enhanced their thermal resistance. Additionally, through introducing polysiloxane as the Si source, ZrSiO4fibers can be synthesized with markedly improved mechanical properties and high-temperature resistance. These blow-spun Zr-based fiber sponges exhibit advantageous internal pore structures, high-temperature elasticity and thermal insulation performance.

High-voltage LiCoO_(2) (LCO) can deliver a high capacity and therefore significantly boost the energy density of Li-ion batteries (LIBs). However, its cyclability is still a major problem in terms of commercial applications. Herein, we propose a simple but effective method to greatly improve the high-voltage cyclability of an LCO cathode by constructing a surface LiF modification layer via pyrolysis of the lithiated polyvinylidene fluoride (Li-PVDF) coating under air atmosphere. Benefitting from the good film-forming and strong adhesion ability of Li-PVDF, the thus-obtained LiF layer is uniform, dense, and conformal;therefore, it is capable of acting as a barrier layer to effectively protect the LCO surface from direct exposure to the electrolyte, thus suppressing the interfacial side reactions and surface structure deterioration. Consequently, the high-voltage stability of the LCO electrode is significantly enhanced. Under a high charge cutoff voltage of 4.6 V, the LiF-modified LCO (LiF@LCO) cathode demonstrates a high capacity of 201 mA h g^(−1) at 0.1 C and a stable cycling performance at 0.5 C with 80.5% capacity retention after 700 cycles, outperforming the vast majority of high-voltage LCO cathodes reported so far.

The ballistic perforation response of composite fabrics made by combining plain weaves with seaming technology is reported and compared with conventional unseamed plain *** effect of the seaming technique on the ballistic resistance of aramid plain fabrics is investigated by varying the seaming *** ballistic experiment uses 8 mm diameter spherical projectiles to impact different fabric sample targets with velocities of 230 m/s and 400 m/*** ballistic performance of seamed and unseamed fabrics is characterized by the specific energy absorption(SEA)values of the *** results show that the seamed fabric has a better energy absorption capacity than the unseamed fabric,e.g.,the SEA of sample 5(seaming lines on every four yarns in a single-ply fabric system)is 135%of sample 1(plain weave without thread seaming).In the single-layer system,the effect of the seaming technique on the energy absorption of the fabric in significant when considering seaming density,seaming orientation,seaming distance,and seaming material on the plain fabric;In addition,it is found that in multi-layer systems,seamed panels(e.g.,sample 7)exhibit better ballistic performance than multi-layer fabrics(e.g.,sample 2),and the specific energy absorption of sample 7 is approximately 156%and 200%of sample 6 and sample 2,***,the energy absorption of the fabric decreases with the increase of impact velocity,which is related to the energy absorption mechanism of the soft fabric system at high impact *** yarn pull-out tests shows that the constraint provided by the seaming thread increases the friction between the fabric-forming ***,when the constraint exceeds a certain level,it is detrimental to the energy absorption of the fabric,which may be due to the overconstraint of yarn mobility.
