Electric transmission behavior of self-assembled Cu–W nano multilayers

Metallic nano multilayers were usually prepared by dual targets alternating deposition method. In this paper, a series of self-assembled Cu–W nano multilayers with different modulation periods were deposited on single crystal silicon substrate by dual targets confocal magnetron sputtering technique. The self-assembled film presented an alternation of W-rich layer and Cu-rich layer. The degree of coherence of the layered interface can be adjusted by controlling both the solid solubility of W-rich...

PEO-PAN-PEO三明治结构新型固态聚合物电解质的研究

为了解决聚丙烯腈(PAN)聚合物电解质膜刚性强、界面接触状况差的问题,将聚氧化乙烯(PEO)电解质膜贴合在PAN电解质膜的两侧,形成三明治结构PEO-PAN-PEO新型聚合物电解质复合膜.在高温下PEO层具有的柔性大幅度增加了电极与电解质的接触面积,降低了界面阻抗,成功充当了全固态锂电池的电解质膜.以金属锂为负极、LiFePO4为正极所组装的全固态锂电池在60℃下工况良好,初始放电比容量是153mAh/g,40周容量保持率为87%.

Anode material with Li-Si nano-domains in three-dimensional carbon network

A micro-nano combined composite with Li-Si alloy nano-domains in three-dimensional carbon network was prepared as a novel electrode material.The carbon network constrained the volume contraction and promoted effectively charge transfer of the whole active material.Meanwhile,the abundant interfaces between Li-Si alloy and carbon bound by Li-C ionic bonds,not only enhanced the delithiation at interface but also ensured the structural integrity.The present composite exhibited excellent electrochemical performance.The specific capacity at the first lithiation was as high as 1133 mAh g~(-1) at a current density of 0.1 A g~(-1),which is superior to those reported for the core-shell structured nanoparticles.The Coulombic Efficiency at the first cycle was 90.4%and kept stable at more than 99.0%after only 10 cycles.The capacity retention was nearly twice as that of the incompact mixture of Li-Si nanoparticles and carbon.The energy density of the full cell constructed by the present composite and sulfur was evaluated to be 3 times as high as that of the commercial lithium-ion batteries.This work provides a new universal strategy for developing Li-rich anode materials with high combination properties and low cost.     

《计算机原理与接口技术》课程教学的思索

《计算机原理与接口技术》课程理论性和实践性结合紧密,软件与硬件相辅相承,教学内容包括计算机原理、汇编语言、接口技术,教学容量大,原理性、逻辑性、综合性强,抽象难懂,学生难学,教师难教.为此本文对此课程的教学进行了案例教学,归纳教学,模块记忆,仿真教学,多媒体演示,综合设计等的教学探索与改进研究.通过这些改进,增强学生学习这门课程的兴趣,提高了教学效果.
