| 1 | Recent research progresses in ether-and ester-based electrolytes for sodium-ion batteries显示文摘Owing to the natural abundance and low cost of sodium resources,sodium-ion batteries(SIBs)have drawn considerable attention for state-of-the-art power storage devices over the last few years.To enable advanced SIBs with a brighter future,great effort has been made,not only through optimizing the electrode materials,but also with rationally designing various electrolyte systems.Among the available electrolyte systems,organic electrolytes,especially those based on esters as well as ethers,are the most promising ones for practical application in the foreseeable future,due to their numerous inherent advantages.This review is concerned with the recent research progresses on organic electrolytes for SIBs,focusing on etherbased and ester-based ones. | Zeheng Lin Qingbing Xia Wanlin Wang Weishan Li Shulei Chou | 2019 | InfoMat2019，1，3： | 12 |
| 2 | Enhancing thermodynamic stability of single-crystal Ni-rich cathode material via a synergistic dual-substitution strategy显示文摘Nickel(Ni)-rich cathode materials have become promising candidates for the next-generation electrical vehicles due to their high specific capacity.However,the poor thermodynamic stability(including cyclic performance and safety performance or thermal stability)will restrain their wide commercial application.Herein,a single-crystal Ni-rich Li Ni_(0.83)Co_(0.12)Mn_(0.05)O_(2) cathode material is synthesized and modified by a dual-substitution strategy in which the high-valence doping element improves the structural stability by forming strong metal–oxygen binding forces,while the low-valence doping element eliminates high Li^(+)/Ni^(2+)mixing.As a result,this synergistic dual substitution can effectively suppress H2-H3 phase transition and generation of microcracks,thereby ultimately improving the thermodynamic stability of Ni-rich cathode material.Notably,the dual-doped Ni-rich cathode delivers an extremely high capacity retention of 81%after 250 cycles(vs.Li/Li+)in coin-type half cells and 87%after 1000 cycles(vs.graphite/Li^(+))in pouch-type full cells at a high temperature of 55℃.More impressively,the dual-doped sample exhibits excellent thermal stability,which demonstrates a higher thermal runaway temperature and a lower calorific value.The synergetic effects of this dual-substitution strategy pave a new pathway for addressing the critical challenges of Ni-rich cathode at high temperatures,which will significantly advance the high-energy-density and high-safety cathodes to the subsequent commercialization. | Jixue Shen Hui Li Haoyu Qi Zhan Lin Zeheng Li Chuanbo Zheng Weitong Du Hao Chen Shanqing Zhang | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
