| 1 | Failure mechanism of bulk silicon anode electrodes for lithium-ion batteries显示文摘Silicon has been investigated extensively as a promising anode material for rechargeable lithium-ion batteries. Understanding the failure mechanism of silicon-based anode electrodes for lithium-ion batteries is essential to solve the problem of low coulombic efficiency and capacity fading on cycling and also to further commercialize this very new energetic material in cells. To reach this goal, the structure changes of bulk silicon particles and electrode after cycling were studied using ex-situ scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The SEM images indicated that the microstructural changes of the bulk silicon particles during cycling led to a layer rupture of the electrode and then the breakdown of the conductive network and the failure of the electrode. The result contributes to the basic understanding of the failure mechanism of a bulk silicon anode electrode for lithium-ion batteries. | Tao Li Juan-Yu Yang Shi-Gang Lu Han Wang Hai-Yang Ding | 2013 | Rare Metals2013，32，3： | 3 |
| 2 | 火花放电和高能球磨组合法制备纳米硅颗粒及微观结构表征显示文摘采用火花放电法制备出粒径均匀分布在30~50 nm的纳米硅颗粒,产量为1 g/h。针对其低产率,在火花放电的基础上组合高能球磨法,成功制备出中径(D50)为80 nm的纳米硅颗粒,产量可达100 g/h。利用SEM、EDS、XRD、TEM等手段分别对产物的微观结构进行表征,结果表明:火花放电法所制备的纳米硅颗粒呈球形,且形貌趋于一致,但颗粒内部出现层错等晶体缺陷及非晶区域;而火花放电和高能球磨组合法制备的纳米硅颗粒呈层片状,其形貌差异较大,但颗粒内部几乎未出现非晶区域,层错缺陷更少,晶体结构更好。 | 曹祥威 赵明才 张林 汪炜 陈秭昕 | 2018 | 电加工与模具2018，，2： | 1 |
| 3 | Mg掺杂SiO_(x)负极材料的电化学性能研究显示文摘采用高温固相法合成Mg掺杂的锂离子电池SiO_(x)负极材料,并探究不同Mg掺杂量对SiO_(x)负极材料电化学性能的影响规律。结果表明,Mg掺杂量为15%(质量分数)的SiO_(x)负极材料具有更优异的首次库伦效率和循环性能,其首次库伦效率可达84.16%,循环100圈后仍具有初始容量的56.03%。适量的Mg掺杂能够消耗SiO_(2)相,生成电化学非活性相MgSiO_(3),抑制不可逆相硅酸锂和氧化锂的生成,从而提高SiO_(x)的电化学性能。 | 杨森 郭致昂 李发丹 赵夷雯 唐博 王振慧 邢安 刘晓燕 | 2023 | 功能材料2023，54，10： | 0 |
