1Efficient potential-tuning strategy through p-type doping for designing cathodes with ultrahigh energy density显示文摘Designing new cathodes with high capacity and moderate potential is the key to breaking the energy density ceiling imposed by current intercalation chemistry on rechargeable batteries.The carbonaceous materials provide high capacities but their low potentials limit their application to anodes.Here,we show that Fermi level tuning by p-type doping can be an effective way of dramatically raising electrode potential.We demonstrate that Li(Na)BCF2/L i(Na)B2C2F2 exhibit such change in Fermi level,enabling them to accommodate Li^+(Na^+)with capacities of 290-400(250-320)mAh g^-1 at potentials of 3.4-3.7(2.7-2.9)V,delivering ultrahigh energy densities of 1000-1500 Wh kg^-1.This work presents a new strategy in tuning electrode potential through electronic band structure engineering.Zhiqiang Wang Da Wang Zheyi Zou Tao Song Dixing Ni Zhenzhu Li Xuecheng Shao Wanjian Yin Yanchao Wang Wenwei Luo Musheng Wu Maxim Avdeev Bo Xu Siqi Shi Chuying Ouyang Liquan Chen 2020National Science Review2020,7,11:1
2Low Temperature Synthesis of Nano Porous 12CaO?7Al_2O_3 Powder by Hydrothermal Method显示文摘Single-phase insulating 12CaO?7Al_2O_3(C12A7) powder was synthesized using an optimized hydrothermal method. Pure phase of C12A7 was got at a comparatively lower temperature(c.a. 300 ℃) than that has been previously reported. The crystallite size of the synthesized C12A7 powder was 7±2 nm. The surface area values calculated for all the samples at a synthesis temperature range of 250-800 ℃ for 5 h were in the range of about 19-24 m^2/g, with pore sizes of 12-20 nm. This low-temperature-based synthetic strategy along with nano porous structures and a high surface area value can facilitate catalyst application.Karim Khan 李佳 ZOU Wenwei XU Wei YANG Ye SONG Weijie 2016Journal of Wuhan University of Technology(Materials Science)2016,31,6:0
