| 1 | Highly reversible lead-carbon battery anode with lead grafting on thecarbon surface显示文摘A novel C/Pb composite has been successfully prepared by electroless plating to reduce the hydrogen evolution and achieve the high reversibility of the anode of lead-carbon battery(LCB). The deposited lead on the surface of C/Pb composite was found to be uniform and adherent to carbon surface. Because lead has been stuck on the surface of C/Pb composite, the embedded structure suppresses the hydrogen evolution of lead-carbon anode and strengthens the connection between carbon additive and sponge lead.Compared with the blank anode, the lead-carbon anode with C/Pb composite displays excellent charge—discharge reversibility, which is attributed to the good connection between carbon additives and lead that has been stuck on the surface of C/Pb composite during the preparation process. The addition of C/Pb composite maintains a solid anode structure with high specific surface area and power volume, and thereby, it plays a significant role in the highly reversible lead-carbon anode. | Jian Yin Nan Lin Wenli Zhang Zheqi Lin Ziqing Zhang Yue Wang Jun Shi Jinpeng Bao Haibo Lin | 2018 | Journal of Energy Chemistry2018，27，6： | 6 |
| 2 | Topology optimization design of micro-mass sensors for maximizing detection sensitivity显示文摘Micro-mass sensors have attracted increasing attention in the fiel of biomolecular and chemical detection. It has been found that the size, shape, and geometry of the structure may affect the performance of the sensor. As a result, a topology optimization methodology is proposed in this paper for the design of micro-mass sensors. A phasefiel function controlled by nodal variables and finit element shape functions is used to describe the configuratio of a sensor in the constructed optimization problem. The design goal is to maximize the mass detection sensitivity. On the basis of these formulations, an optimization algorithm is constructed using the finit element method and the method of moving asymptotes. Numerical examples are presented to demonstrate the validity of the proposed problem formulation. The results suggest that the performance of the micro-mass sensor can be improved by using the proposed approach. | Zheqi Lin Xuansheng Wang Yiru Ren | 2015 | Acta Mechanica Sinica2015，31，4： | 1 |
| 3 | Lead‑Carbon Batteries toward Future Energy Storage:From Mechanism and Materials to Applications显示文摘The lead acid battery has been a dominant device in large-scale energy storage systems since its invention in 1859.It has been the most successful commercialized aqueous electrochemical energy storage system ever since.In addition,this type of battery has witnessed the emergence and development of modern electricity-powered society.Nevertheless,lead acid batteries have technologically evolved since their invention.Over the past two decades,engineers and scientists have been exploring the applications of lead acid batteries in emerging devices such as hybrid electric vehicles and renewable energy storage;these applications necessitate operation under partial state of charge.Considerable endeavors have been devoted to the development of advanced carbon-enhanced lead acid battery(i.e.,lead-carbon battery)technologies.Achievements have been made in developing advanced lead-carbon negative electrodes.Additionally,there has been significant progress in developing commercially available lead-carbon battery products.Therefore,exploring a durable,long-life,corrosion-resistive lead dioxide positive electrode is of significance.In this review,the possible design strategies for advanced maintenance-free lead-carbon batteries and new rechargeable battery configurations based on lead acid battery technology are critically reviewed.Moreover,a synopsis of the lead-carbon battery is provided from the mechanism,additive manufacturing,electrode fabrication,and full cell evaluation to practical applications. | Jian Yin Haibo Lin Jun Shi Zheqi Lin Jinpeng Bao Yue Wang Xuliang Lin Yanlin Qin Xueqing Qiu Wenli Zhang | 2022 | Electrochemical Energy Reviews2022，5，3： | 1 |
| 4 | Topology optimization of piezocomposite resonator for maximizing excitation strength and synthesizing desired eigenmodes显示文摘A topology optimization method is proposed for the design of piezocomposite resonator with the aim of maximizing excitation strength and synthesizing desired eigenmodes.The objective function consists of maximizing the electromechanical coupling strength at the mode of interest.The topology layout of a structure with desired eigenmodes is obtained by adding the modal assurance criterion as additional constraint in the topology optimization model.Numerical examples are presented and the results illustrate that aside from maximizing the electromechanical coupling strength,the existing eigenmode of the piezocomposite resonator can be modified to be the desired one at the mode of interest. | Xuansheng Wang Zheqi Lin Yiru Ren | 2017 | Acta Mechanica Solida Sinica2017，30，5： | 0 |
