* 9761362肖 这个小企业创新研究第一阶段项目的目的是证明利用一个令人兴奋的新类别的“纳米”材料（即纳米材料）的独特性能的可行性。几个纳米量级的原子级颗粒，其中1 nm = 10埃）作为高性能可再充电碱性镍电池的活性成分。 US Nanocorp（USN）的负责人已经开发出合成和加工纳米结构电池材料的专有技术。 USN已经开始努力制造高密度镍电极，其中活性材料是纳米多孔的（和中孔的），使得孔表面积保持高以用于有效的电解质冲洗，但是与由常规的和所谓的“球形”氢氧化镍配制的电极相比，总孔体积减小。 增加的密度导致更高的容量。 USN在初步的实验室电池测试中实现了高利用率。 第二阶段计划将开发基于优化电极的原型电池。 这种新方法可以应用于各种电池材料。可充电电池包括全球范围内超过160 B美元/年的业务，其中碱性电池占20%的市场份额（30 B美元/年）。 这将对用于医疗、商业（电动工具）和消费应用的改进电池以及用于无绳割草机、踏板车、电动车辆和混合动力车辆的大容量电池产生深远的影响。 ***

*** 9761362 Xiao This Small Business Innovation Research Phase I project aims to demonstrate the feasibility of exploiting the unique properties of an exciting new class of "nanophase" materials (ie. atomic-scale particles on the order of several manometers, where 1 nm = 10 angstroms) as the active ingredients for high performance rechargeable nickel alkaline batteries. US Nanocorp's (USN) principals have developed proprietary techniques for the synthesis and processing of nanostructred battery materials. USN has begun efforts to fabricate high density nickel electrodes where the active material is nanoporous (and mesoporous), so that the pore surface area remains high for effective electrolyte irrigation, yet the total pore volume is reduced in comparison to electrodes formulated from conventional and so called "spherical" nickel hydroxide. The increased density results in higher capacity. High utilization has been achieved by USN in preliminary lab cell tests. The Phase II program will develop prototype cells based on optimized electrodes. This novel approach can be applied to a wide array of battery materials. Rechargeable batteries comprise a word-wide business of more than $16 B/annum, of which alkaline batteries have a 20% market share ($3 B/annum). This would have profound implications for improved batteries for medical, commercial (power tool), and consumer applications, as well as large capacity batteries for cordless lawn mowers, scooters, electric vehicles and hybrid vehicles. ***
