As the increasing demands for large-scale energy applications such as electric vehicles(EVs) and hybrid electric vehicles(HEVs),it is critical to develop electrodes with high capacity and rate capability.[1] In this abstract,polyhedron Mn2O3 with small interior cavity(mini-hollow polyhedron Mn2O3 for short) by using Mn-based MOFs as precursor was obtained.As is shown in Figure 1a.all the peaks can be well indexed to cubic Mn2O3(JCPDS no.41-1442).Figure 1(b) depicts that the polyhedron Mn2O3 is well dispersed without any aggregation,reaching a length of～0.6-1.2 μm.The smooth surface suggests its single-crystal character.The high-angle annular dark-field scanning transmission electron microscope(HAADF-STEM) image(Figure1c) further confirms the hollow structure with a thick shell and mini-hollow cavity,different from the conventional hollow structure with a thin shell and large-hollow cavity.

复合材料钉群连接是复合材料结构的重要连接形式，也是结构承载的薄弱环节。其失效分析是复合材料结构设计和分析的重要环节。钉群连接的失效分析分为两步：首先进行钉载分配分析，以确定外载荷在各个螺栓的分布情况；然后根据各螺栓承受的载荷，对单个钉孔进行失效评价，其中，挤压和旁路载荷作用下最危险的钉孔处首先失效。因此，深入研究复合材料钉群连接钉载分配测试和预测方法十分必要。
为了发展一种应用于风力机分段叶片的新型连接构造，结合经典层合板理论，首次设计并试制了一只长为13.5米的复合材料分段连接的箱型梁，该连接结构由螺栓套和双头螺栓组成.接着对分段式箱型梁进行模态测试和弯曲载荷作用下的静力试验，以及有限元多维混合建模分析，结果表明：模态频率和挠度的数值分析值与实验吻合很好，验证了模型的有效性，结构的大变形非线性效应不明显，在临近连接局部，复合材料铺层结构存在明显的应力集
基于二维有限元分析模型,提出了一种快速预测复合材料多钉连接钉载分配的分析方法.螺栓采用Fastener单元和Link单元模拟.Fastener单元模拟螺栓和孔之间的挤压作用,Link单元则模拟螺栓的剪切和弯曲刚度.Link单元的刚度通过单钉连接的三维细节分析模型计算得到,以捕捉螺栓端头形式、次弯曲等因素对钉载分配的影响.最后模型通过三维有限元模型和试验数据进行了校核和验证,结果显示所提出的二维模型

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[
