that less vertical curvature values correspond to less riding time. The riding performance formulae were obtained with the variables of riding time, riding velocity and vertical curvature of cycling..., these variables lead to varied designs of cycling tracks and finally affect the racing performance [6-7]. However, there are few literatures evaluating the quality and effectiveness of different......

Improved High-rate Performance and Cycling Stability of 1D LiFePO4 Nanorods by a Facile Annealing Process王雪飞1,WANG Yan1,CHENG Lin1,WU Jing1,余火根1,胡志坚21. Department of Chemistry, Wuhan University... performance. However, our previous synthesized LiFePO4 nanorods only exhibited low high-rate and slightly unstable cycle performance. Possible reasons are the poor crystallization and Fe2+ oxidation......
FePO4-coated Li[Li0.2Ni0.13Co0.13Mn0.54]O2 with improved cycling performance as cathode material for Li-ion batteriesZhong Wang1,2,Hua-Quan Lu1,2,Yan-Ping Yin1,2,Xue-Yi Sun1,2,Xiang-Tao Bai1,2,Xue... initial discharge capacity and columbic efficiency compared to the pristine one. More significantly, the FePO4 coating layer has a much positive influence on the cycling performance. The FePO4 -coated......
Supercapacitor electrode based on few-layer h-BNNSs/rGO composite for wide-temperature-range operation with robust stable cycling performanceTao Yang1,Hui-juan Liu1,Fan Bai1,En-hui Wang1,Jun-hong...-BNNSs/rGO electrode exhibited robustness to wide-temperature-range operations from-10 to 50℃. When the electrodes worked in a neutral aqueous electrolyte(1 M Na2 SO4), they showed a great stable cycling......
