| 1 | Nanostructured strategies towards boosting organic lithium-ion batteries显示文摘Pursuing material development for next-generation batteries,organic electrode materials have shown great potential for lithium-ion batteries.However,their widespread adopting is plagued by intrinsic problems such as poor electronic conductivity,high dissolution inside electrolytes and unstable chemical peculiarity.Recently,nanostructured-strategies promoted organic electrodes with exotic properties for enhancing electron and ion transport together with the stability during electrochemical process,have received increasing attention and have been extensive applied in boosting the organic lithium-ion based energy storage.In this review,we summarize the applications of nanostructures to improve the performance of both organic anodes and cathodes,including(i)nanoscale design of zero-dimensional organic electrode materials,(ii)strategies of one-dimensional nanostructured organic electrode materials,(iii)construction of two-dimensional nanosized organic composite electrodes,and(iv)three-dimensional exploration of nanosized organic electrodes.We hope to stimulate high-quality applied research on understanding and handling the relationship between the nanostructure and performance of organic lithium-ion batteries that might speed up the commercialization of organic lithium ion batteries. | Yujing Liu Guoyuan Sun Xiaohan Cai Fan Yang Cong Ma Min Xue Xinyong Tao | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |
| 2 | Solid polymer electrolytes in all-solid-state lithium metal batteries:From microstructures to properties显示文摘All-solid-state lithium(Li)metal batteries(ASSLMBs)are considered one of the most promising secondary batteries due to their high theoretical capacity and high safety performance.However,low room-temperature ionic conductivity and poor interfacial stability are two key factors affecting the practical application of ASSLMBs,and our understanding of the mechanisms behind these key problems from microscopic perspective is still limited.In this review,the mechanisms and advanced characterization techniques of ASSLMBs are summarized to correlate the microstructures and properties.Firstly,we summarize the challenges faced by solid polymer electrolytes(SPEs)in ASSLMBs,such as the low roomtemperature ionic conductivity and the poor interfacial stability.Secondly,several typical improvement methods of polymer ASSLMBs are discussed,including composite SPEs,ultra-thin SPEs,SPEs surface modification and Li anode surface modification.Finally,we conclude the characterizations for correlating the microstructures and the properties of SPEs,with emphasis on the use of emerging advanced techniques(e.g.,cryo-transmission electron microscopy)for in-depth analyzing ASSLMBs.The influence of the microstructures on the properties is very important.Until now,it has been difficult for us to understand the microstructures of batteries.However,some recent studies have demonstrated that we have a better understanding of the microstructures of batteries.Then we suggest that in situ characterization,nondestructive characterization and sub-angstrom resolution are the key technologies to help us further understand the batteries'microstructures and promote the development of batteries.And potential investigations to understand the microstructures evolution and the batteries behaviors are also prospected to expect further reasonable theoretical guidance for the design of ASSLMBs with ideal performance. | Zongxi Lin Ouwei Sheng Xiaohan Cai Dan Duan Ke Yue Jianwei Nai Yao Wang Tiefeng Liu Xinyong Tao Yujing Liu | 2023 | Journal of Energy Chemistry2023，，6： | 1 |
| 3 | Hemodynamic evaluation of different stent graft schemes in aortic arch covered stent implantation显示文摘Implantation of the left subclavian artery(LSA)stent graft used in fenestration technique of the thoracic endovascular aortic repair(TEVAR)may interfere with the aortic helical blood flow that is believed to have important protective functions against atherogenesis.The present study investigated four different LSA stent graft implantation schemes for their resulted blood flow patterns in the thoracic aortic with hemodynamic computational simulation methods:the flush branch(FB),the protruding branch(PB),the straight cuff branch(SCB)and the cured cuff branch(CCB).The results showed that the PB scheme could slightly enhance helicity of the swirling flow in the aorta,but the other three schemes had less effect on blood flow helicity.The PB scheme produced lowTAWSS,high-OSI and high-RRT around the LSA root,and the FB scheme had similar TAWSS,OSI and RRT in both value and distribution to those in the aorta without LSA stent graft implantation.The SCB and CCB schemes led to less area of high-OSI and high-RRT values along the walls of the LSA branch arteries.The results also showed that the PB scheme would significantly reduce blood supply to the LSA,on the contrary,the CCB scheme enhanced LSA blood supply and less effect on the total blood supply to the three branches of the thoracic aorta.In summary,all of the four schemes have no significant effect on the aortic swirling flow,however,in the terms of TAWSS,OSI,RRT and blood supply to the LSA,the CCB model might be the best option with less area of low-WSS,high-OSI,high-RRT and well blood supply in the LSA. | Jingxin Liu Xinyong Cai Yuliang Zhan Hongmin Zhu Haiyong Ao Yizao Wan Honglin Luo Zhiwei Yang Quanchao Zhang | 2022 | Medicine in Novel Technology and Devices2022，，1： | 0 |
