嵌入型过渡金属氧化物因具有安全的工作电压、高比容量和快速的嵌锂能力而受到广泛关注.但低本征电导率特性严重影响其作为锂电负极材料的寿命和性能.本文通过简便易行、可规模化放大的二氧化碳热处理方法构筑了具有新型嵌覆型碳结构的Nb_(2)O_(5)/C纳米杂化材料.在控制碳含量的前提下,实现了颗粒聚集体内部表面可控碳包覆.以嵌覆型碳结构的Nb_(2)O_(5)/C纳米杂化材料为负极组装的锂离子电池在40 mA g(-1)电流密度下容量可达387 mA hg(-1),而在200 mA g(-1)电流密度下循环500次后,容量保持率在92%以上.采用电化学滴定、差分电化学质谱(DEMS)等方法对嵌覆型五氧化二铌/碳纳米杂化材料脱嵌锂动力学过程以及产气行为进行了研究.本文提出的嵌覆型碳结构有望为高性能嵌入型过渡金属氧化物的结构设计提供参考.

Impact of Electric Vehicles on Travel and Electricity Demand in Metropolitan Area： A Case Study in Nagoya

引用

Journal of Civil Engineering and Architecture 2015年第3期9卷 341-349页

作者： Ryo Kanamori Takayuki Morikawa Masaya Okumiya Toshiyuki Yamamoto Takayuki Ito Institute of Innovation for Future Society Nagoya University Nagoya 464-8603 Japan Department of Environmental Engineering and Architecture Nagoya University Nagoya 464-8603 Japan Eco.Topia Science Institute Nagoya University Nagoya 464-8603 Japan Department of co.puter Science and Engineering Nagoya Institute of Technology Nagoya 466-8555 Japan

In this study, we examine the impacts that EVs (electric vehicles) have on vehicle usage patterns and environmental improvements, using our integrated travel demand forecasting model, which can simulate an individual activity-travel behavior in each time period, as well as co.sider an induced demand by decreasing travel co.t. In order to examine the effects that charging/discharging have on the demand in electricity, we analyze scenarios based on the simulation results of the EVs" parking location, parking duration and the battery state of charge. From the simulation, result under the ownership rate of EVs in the Nagoya metropolitan area in 2020 is about 6%, which turns out that the total co. emissions have decreased by 4% although the situation of urban transport is not changed. After calculating the electricity demand in each zone using architectural area and basic units of hourly power co.sumption, we evaluate the effect to decrease the peak load by V2G (vehicle-to-grid). Acco.ding to the results, if EV drivers charge at home during the night and discharge at work during the day, the electricity demand in Nagoya city increases by approximately 1%, although changes in each individual zone range from -7% to +8%, depending on its characteristics.
