| 1 | Dense ceramics with complex shape fabricated by 3D printing:A review显示文摘Three-dimensional(3D)printing technology is becoming a promising method for fabricating highly complex ceramics owing to the arbitrary design and the infinite combination of materials.Insufficient density is one of the main problems with 3D printed ceramics,but concentrated descriptions of making dense ceramics are scarce.This review specifically introduces the principles of the four 3D printing technologies and focuses on the parameters of each technology that affect the densification of 3D printed ceramics,such as the performance of raw materials and the interaction between energy and materials.The technical challenges and suggestions about how to achieve higher ceramic density are presented subsequently.The goal of the presented work is to comprehend the roles of critical parameters in the subsequent 3D printing process to prepare dense ceramics that can meet the practical applications. | Zhe Chen Xiaohong Sun Yunpeng Shang Kunzhou Xiong Zhongkai Xu Ruisong Guo Shu Cai Chunming Zheng | 2021 | Journal of Advanced Ceramics2021，10，2： | 10 |

| 4 | Novel fast lithium-ion conductor LiTa_(2)PO_(8)enhances the performance of poly(ethylene oxide)-based polymer electrolytes in all-solid-state lithium metal batteries显示文摘At present,replacing the liquid electrolyte in a lithium metal battery with a solid electrolyte is considered to be one of the most powerful strategies to avoid potential safety hazards.Composite solid electrolytes(CPEs)have excellent ionic conductivity and flexibility owing to the combination of functional inorganic materials and polymer solid electrolytes(SPEs).Nevertheless,the ionic conductivity of CPEs is still lower than those of commercial liquid electrolytes,so the development of high-performance CPEs has important practical significance.Herein,a novel fast lithium-ion conductor material LiTa_(2)PO_(8) was first filled into poly(ethylene oxide)(PEO)-based SPE,and the optimal ionic conductivity was achieved by filling different concentrations(the ionic conductivity is 4.61×10^(-4)S/cm with a filling content of 15 wt%at 60℃).The enhancement in ionic conductivity is due to the improvement of PEO chain movement and the promotion of LiTFSI dissociation by LiTa_(2)PO_(8).In addition,LiTa_(2)PO_(8) also takes the key in enhancing the mechanical strength and thermal stability of CPEs.The assembled LiFePO_(4) solid-state lithium metal battery displays better rate performance(the specific capacities are as high as 157.3,152,142.6,105 and 53.1 mAh/g under0.1,0.2,0.5,1 and 2 C at 60℃,respectively)and higher cycle performance(the capacity retention rate is86.5%after 200 cycles at 0.5 C and 60℃).This research demonstrates the feasibility of LiTa_(2)PO_(8) as a filler to improve the performance of CPEs,which may provide a fresh platform for developing more advanced solid-state electrolytes. | Ying Na Zhe Chen Zhongkai Xu Qi An Xi Zhang Xiaohong Sun Shu Cai Chunming Zheng | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 5 | Application Prospect of 3D Printing Technology in Refractory Precast Components显示文摘3D printing is a rapid prototyping technology to shape materials or objects through printing layer by layer driven by digital models, which can be adopted for the manufacture of refractory precast components. Thus, the production technology of refractory precast components as well as the technique and advantages of 3D printing was introduced. The feasibility and application prospect of 3D printing concrete, contour crafting and adhesive 3D printing in refractory precast components were presented. | MAO Limin HU Chenxi YANG Haiyun LIU Jiwang HE Zehong QING Xiaobin CAI Zhongkai | 2019 | China's Refractories2019，28，2： | 0 |
| 6 | Improving cycling stability of Bi-encapsulated carbon fibers for lithium/sodium-ion batteries by Fe_(2)O_(3) pinning显示文摘Bi draws increasing attention as anode materials for lithium-ion batteries and sodium-ion batteries due to its unique layered crystal structure,which is in favor of achieving fast ionic diffusion kinetics during cycling.However,the dramatic volume expansion upon lithiation/sodiation and an insufficient theoretical capacity of Bi greatly hinder its practical application.Herein,we report the Fe_(2 )O_(3) nanoparticle-pinning Bi-encapsulated carbon fiber composites through the electrospinning technique.The introduction of Fe_(2 )O_(3) nanoparticles can prevent the growth and aggregation of Bi nanoparticles during synthetic and cycling processes,re s pectively.Fe_(2)O_(3) with high specific capacity also contributes to the specific capacity of the composites.Consequently,the as-prepared Bi-Fe_(2)O_(3)/carbon fiber composite exhibits outstanding long-term stability,which delivers reversible capacities 504 and 175 mAh/g after1000 cycles at 1 A/g for lithium-ion and sodium-ion batteries,respectively. | Tianyi Hou Anran Fan Xiaohong Sun Xi Zhang Zhongkai Xu Shu Cai Chunming Zheng | 2021 | Chinese Chemical Letters2021，32，8： | 0 |
