*** 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. ***

*9761362肖这个小企业创新研究第一阶段项目旨在展示利用一种令人兴奋的新类别的“纳米”材料(即。作为高性能可充电碱性镍电池的活性成分，我们开发了几个压力计数量级的原子尺度颗粒(1纳米=10埃)。美国纳米科技公司(US Nanocorp)的负责人开发了用于合成和加工纳米结构电池材料的专利技术。USN已经开始努力制造活性材料为纳米孔(和介孔)的高密度镍电极，以便孔表面积保持高以进行有效的电解液冲洗，但与传统的和所谓的球形氢氧化镍制成的电极相比，总孔体积有所减少。密度的增加会导致更高的容量。USN在初步的实验室电池测试中实现了高利用率。第二阶段计划将在优化电极的基础上开发原型电池。这种新的方法可以应用于多种电池材料。充电电池的全球业务超过160亿美元/年，其中碱性电池占有20%的市场份额(30亿美元/年)。这将对医疗、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、滑板车、电动汽车和混合动力汽车的大容量电池产生深远的影响。***
