By establishing the representative volume element (RVE) model of three-dimensional (3D) six-directional braided composites, stiffness prediction of the composite under different braiding angle and fib
MnO作为一种过渡金属氧化物,其比容量高(理论容量756 mAh·g-1,是石墨的2倍)、密度大(5.43g·cm-3)、电动势低(1.032Vvs.Li+/Li)、环境友好[1].而广西的锰资源占全国锰矿资源的三分之一,居全国首位,高附加值MnO/C负极材料的开发,可为锰资源的开发利用提供新的发展思路,促进我国及广西锰资源的深加工利用,具有良好的应用前景.针对目前文献中报道的MnO负极材料存在电
Lithium-ion batteries are widely used in modern instruments and devices because of their long lifetime,environmental benignity and high energy density.In recent years,intensive research has been condu
Despite most porous silicon-based anode materials manifest excellent lithium-ions storage properties and have great potential application in the next generation lithium-ion batteries,the scalable and
目前商业化锂离子电池负极材料多使用石墨类碳材料,由于受到材料比容量低的限制(石墨类碳材料的理论容量仅为372mAh/g),不能满足高容量锂离子电池的需求.过渡金属氧化物具有较高的可逆比容量( 500-1OOOmAh/g),作为锂离子电池负极材料早有研究,但工作电压较高.复合过渡金属氧化物能综合运用各种单一过渡金属氧化物的电化学活性,很有可能成为下一代极具潜力的高比能量、高比功率锂离子电池负极材料[
