This Partnership for Innovation project from Cornell University will create carbon-based nanocomposite materials suitable for advanced batteries, super capacitors, and magnetic storage media. The approach relies on co-polymerization of inorganic and organic polymer precursors to create composite materials in which inorganic nanoparticles are uniformly embedded in an electrically conductive carbon host. This platform technology will be applied to the development of new high-energy battery cathodes and anodes based on metal/carbon, metal sulfide/carbon, and metal oxide/carbon nanocomposites. Batteries based on the new composite electrodes offer energy storage capacities four to five times higher than the most advanced units in use today and are expected to find applications in portable electronic devices and electric vehicles. By incorporating highly conductive graphene structures into the composite materials, the project further aims to develop supercapacitors with high power and high energy storage capacities for the power utility grid storage. In addition, the project utilizes mixed metal precursors to create composites based on metal alloys and inter-metallic nanoparticles that facilitate independent control of the magnetic permeability and electrical conductivity.The broader impacts of this research ultimately will include acceleration of commercialization of several unique battery systems with potential market-changing impacts. The global market for secondary batteries alone was estimated to be $11-$13 billion in 2010 and is expected to quadruple by 2020. By bringing together researchers from Cornell University, known world-wide for their innovative contributions in the rechargeable batteries field, with two Up-State New York technology concerns possessing complementary expertise on materials synthesis, formulation, and manufacturing, the project creates a path toward commercial deployment of lithium battery systems that offer multiple unique features. These features include best-in-class energy storage capacity and best-in-class power density. The project will also develop materials and manufacturing processes for battery electrodes, supercapacitors, and magnetic materials that are familiar from other sectors of technology. By doing so, costs associated with deployment of battery manufacturing processes will be contained--a required first-step for improving competitiveness of the new lithium battery systems in the marketplace.Partners at the inception of the project are Cornell University as the lead academic institution andSmall Business partners Graphene Devices Ltd., Rochester, New York; and NOHMs Technologies, Ithaca New York.

康奈尔大学的这一创新伙伴关系项目将创造出适用于先进电池、超级电容器和磁存储介质的碳基纳米复合材料。该方法依赖于无机和有机聚合物前体的共聚来创建复合材料，其中无机纳米颗粒均匀地嵌入到导电碳主体中。该平台技术将应用于基于金属/碳、金属硫化物/碳、金属氧化物/碳纳米复合材料的新型高能电池正负极的开发。基于新型复合电极的电池提供的储能容量是目前使用的最先进单元的四到五倍，预计将在便携式电子设备和电动汽车中得到应用。通过将高导电石墨烯结构引入复合材料，该项目进一步旨在开发用于电力公用事业电网存储的高功率和高储能能力的超级电容器。此外，该项目利用混合金属前驱体来创造基于金属合金和金属间纳米颗粒的复合材料，以便于独立控制磁导率和电导率。这项研究的更广泛影响最终将包括加速几个具有潜在市场变化影响的独特电池系统的商业化。2010年，仅二次电池的全球市场估计就达到110亿至130亿美元，预计到2020年将翻两番。通过将世界闻名的康奈尔大学的研究人员与纽约州北部在材料合成、配方和制造方面拥有互补专业知识的两家公司的研究人员聚集在一起，该项目为提供多种独特功能的锂电池系统的商业部署开辟了一条道路。这些功能包括一流的储能容量和一流的功率密度。该项目还将开发电池电极、超级电容器和其他技术部门熟悉的磁性材料的材料和制造工艺。通过这样做，与部署电池制造工艺相关的成本将得到控制，这是提高新锂电池系统在市场上竞争力所必需的第一步。项目开始时的合作伙伴是作为主要学术机构的康奈尔大学和位于纽约罗切斯特的小型商业合作伙伴Graphene Devices Ltd.；以及位于纽约伊萨卡的NOHMS技术公司。
