| 1 | Emerging miniaturized energy storage devices for microsystem applications:from design to integration显示文摘The rapid progress of micro/nanoelectronic systems and miniaturized portable devices has tremendously increased the urgent demands for miniaturized and integrated power supplies.Miniaturized energy storage devices(MESDs),with their excellent properties and additional intelligent functions,are considered to be the preferable energy supplies for uninterrupted powering of microsystems.In this review,we aim to provide a comprehensive overview of the background,fundamentals,device configurations,manufacturing processes,and typical applications of MESDs,including their recent advances.Particular attention is paid to advanced device configurations,such as two-dimensional(2D)stacked,2D planar interdigital,2D arbitrary-shaped,three-dimensional planar,and wire-shaped structures,and their corresponding manufacturing strategies,such as printing,scribing,and masking techniques.Additionally,recent developments in MESDs,including microbatteries and microsupercapacitors,as well as microhybrid metal ion capacitors,are systematically summarized.A series of on-chip microsystems,created by integrating functional MESDs,are also highlighted.Finally,the remaining challenges and future research scope on MESDs are discussed. | Huaizhi Liu Guanhua Zhang Xin Zheng Fengjun Chen Huigao Duan | 2020 | International Journal of Extreme Manufacturing2020，2，4： | 4 |
| 2 | 合成聚合物衍生硬碳在钠离子电池中的研究进展显示文摘在过去的10年里,便携式电子设备和电动汽车的迅速发展引起了人们对电化学储能系统商业化的兴趣.因钠元素在地球上的丰富储备,钠离子电池是目前锂离子电池最有前途的替代品,作为一种新兴的低成本储能技术,在大规模电化学储能中具有较好的应用前景.由于碳材料的原料丰富、成本低廉、具有低的电化学电位,通常是电池负极材料的首选.其中,石墨具备良好的化学稳定性和相对较高的比容量被广泛用于商业锂离子电池.但是由于热力学的限制,钠与石墨的层间化合物不存在,将石墨作为钠离子电池的负极几乎不显示储钠活性,这导致容量的极大损失.硬碳具有可膨胀的石墨烯夹层、合适的工作电压和相对较低的成本,被认为是最有可能实现商业化应用的钠离子电池负极材料.合成聚合物作为硬碳前驱体的重要来源,可以通过调控化学组成结构和工艺条件,实现不同的结构和形貌,以满足不同的性能需求.本文综述了近年来以合成聚合物为前驱体制备硬碳负极材料的研究进展,重点介绍了合成聚合物的种类和制备方法对硬碳材料的微观结构形态的影响,以及形貌结构和电化学性能之间的关系.此外,还探讨了提升硬碳材料电化学性能的关键因素,并提出了未来主要发展的方向,促进钠离子电池实现商业化. | 李瑀 付浩宇 封伟 | 2022 | 天津大学学报(自然科学与工程技术版)2022，55，1： | 2 |
| 3 | Recent Advances in Molybdenum-Based Materials for Lithium-Sulfur Batteries显示文摘Lithium-sulfur(Li-S)batteries as power supply systems possessing a theoretical energy density of as high as 2600 Wh kg−1 are considered promising alternatives toward the currently used lithium-ion batteries(LIBs).However,the insulation characteristic and huge volume change of sulfur,the generation of dissolvable lithium polysulfides(LiPSs)during charge/discharge,and the uncontrollable dendrite formation of Li metal anodes render Li-S batteries serious cycling issues with rapid capacity decay.To address these challenges,extensive efforts are devoted to designing cathode/anode hosts and/or modifying separators by incorporating functional materials with the features of improved conductivity,lithiophilic,physical/chemical capture ability toward LiPSs,and/or efficient catalytic conversion of LiPSs.Among all candidates,molybdenum-based(Mo-based)materials are highly preferred for their tunable crystal structure,adjustable composition,variable valence of Mo centers,and strong interactions with soluble LiPSs.Herein,the latest advances in design and application of Mo-based materials for Li-S batteries are comprehensively reviewed,covering molybdenum oxides,molybdenum dichalcogenides,molybdenum nitrides,molybdenum carbides,molybdenum phosphides,and molybdenum metal.In the end,the existing challenges in this research field are elaborately discussed. | Henghan Dai Lumin Wang Yue Zhao Jialu Xue Ruicong Zhou Chenyang Yu Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Research2021，，1： | 1 |
