4Advanced characterizations and measurements for sodium-ion batteries with NASICON-type cathode materials显示文摘NASICON (Na superionic conductor)-type cathode materials for sodium-ion batteries (SIBs) have attractedextensive attention due to their mechanically robust three-dimensional (3D) framework, which has sufficient openchannels for fast Na^(+) transportation. However, they usually suffer from inferior electronic conductivity and lowcapacity, which severely limit their practical applications. To solve these issues, we need to deeply understand thestructural evolution, redox mechanisms, and electrode/electrolyte interface reactions during cycling. Recently,rapid developments in synchrotron X-ray techniques, neutron-based resources, magnetic resonance, as well asoptical and electron microscopy have brought numerous opportunities to gain deep insights into the Na-storagebehaviors of NASICON cathodes. In this review, we summarize the detection principles of advanced characterization techniques used with typical NASICON-structured cathode materials for SIBs. The special focus is on bothoperando and ex situ techniques, which help to investigate the relationships among phase, composition, andvalence variations within electrochemical responses. Fresh electrochemical measurements and theoretical computations are also included to reveal the kinetics and energy-storage mechanisms of electrodes upon charge/discharge. Finally, we describe potential new developments in NASICON-cathodes with optimized SIB systems,foreseeing a bright future for them, achievable through the rational application of advanced diagnostic methods.Yukun Liu Jie Li Qiuyu Shen Jian Zhang Pingge He Xuanhui Qu Yongchang Liu 2022eScience2022,2,1:1
5Study on Redevelopment of Kunming West Mountain Forest Park in the View of Experience Economy显示文摘At the background of the experience economy becoming major economic form in place of the service economy,forest experience develops vigorously and becomes a new approach for people alleviating pressure,acquiring knowledge,and relaxation. On the basis of analyzing concept and characteristics of the forest experience,this paper analyzed current situation of forest experience by taking Kunming West Mountain Forest Park as an example. It found there are existing problems in subject image,development methods and degree,professional personnel and concept. In view of these problems,it came up with recommendations including determining subject image,designing special products,accelerating cultivation of professional personnel,and strengthening training of forest experience concept. It is expected to provide reference for multi-functional use theory of China and provide ideas for developing forest experience projects.Rumin ZHENG Shuo ZHEN Zexiong YANG Xiping CHENG Pingge HE 2016Asian Agricultural Research2016,8,2:0
6Manipulating interfacial stability of LiNi0.5Co0.3Mn0.2O2 cathode with sulfide electrolyte by nanosized LLTO coating to achieve high-performance all-solid-state lithium batteries显示文摘All-solid-state lithium batteries(ASSLBs) based on sulfide solid-state electrolytes and high voltage layered oxide cathode are regarded as one of the most promising candidates for energy storage systems with high energy density and high safety.However,they usually suffer poor cathode/electrolyte interfacial stability,severely limiting their practical applications.In this work,a core-shell cathode with uniformly nanosized Li0.5La0.5TiO3(LLTO) electrolyte coating on LiNi0.5Co0.3Mn0.2O2(NCM532) is designed to improve the cathode/electrolyte interface stability.Nanosized LLTO coating layer not only significantly boosts interfacial migration of lithium ions,but also efficiently alleviates space-charge layer and inhibits the electrochemical decomposition of electrolyte.As a result,the assembled ASSLBs with high mass loading(9 mg cm-2)LLTO coated NCM532(LLTO@NCM532) cathode exhibit high initial capacity(135 mAh g^(-1)) and excellent cycling performance with high capacity retention(80% after 200 cycles) at 0.1 C and 25℃.This nanosized LLTO coating layer design provides a facile and effective strategy for constructing high performance ASSLBs with superior interfacial stability.Jingguang Yi Pingge He Hong Liu Haifang Ni Zhiming Bai Li-Zhen Fan 2021Journal of Energy Chemistry2021,30,1:0
