SBIR Phase I: Planar ZEBRA Battery Development

这个小型企业创新研究(SBIR)第一阶段的项目是开发一种平面、高度紧凑的钠-贝塔可充电电池，该电池使用夹在液态钠和氯化镍盐之间的钠离子导电贝塔氧化铝固体电解液盘(P-斑马电池)。所有商用的钠-贝塔电池技术都使用较厚的钠基管，导致相对较低的比能量密度和较大的热量块，阻碍了快速热循环。在该项目中，将使用专利气相工艺开发和制造高性能的平面钠基盘，具有高强度和高抗湿性和抗二氧化碳侵蚀。P-Zebra电池可在200？C至400？C的广泛温度范围内工作，提供适合高往返效率的间歇性可再生能源存储应用(风能、太阳能和地热)的集成和操作灵活性，或适合与内燃机或固态氧化物燃料电池(SOFC)的热集成，用于插电式混合动力汽车(PHEV)应用，扩大续航里程。这项研究的更广泛的商业影响是提供一种低成本、高度可靠的电能存储系统，该系统集成了广泛的发电系统。它包括可缓解电网暂态问题的快速市场渗透的可再生能源电力系统，以及延长行驶距离的汽油内燃机或用于PHEV的先进SOFC。拟议中的p-斑马电池技术的成功开发和部署将有助于美国建立关键的新产业，并恢复美国在大规模电能储存领域的领导地位。

This Small Business Innovation Research (SBIR) Phase I project is on the development of a planar, highly compact, sodium-beta rechargeable battery using sodium-ion conducting beta alumina solid electrolyte disc (Na-BASE) sandwiched between a liquid sodium and a nickel chloride salt, (p-ZEBRA battery). All commercially available sodium-beta battery technologies use thick Na-BASE tubes, resulting in relatively low specific energy densities and large thermal masses that inhibit fast thermal cycling. In this project, highly performing planar Na-BASE discs, possessing high strength and high resistance to moisture and CO2 attack, will be developed and manufactured using a patented vapor phase process. The p- ZEBRA battery allows operation over a wide temperature range from 200ºC to 400ºC, delivering the integration and operation flexibility suitable for intermittent renewable energy storage applications (wind, solar power and geothermal) with high round-trip efficiencies, or thermal integration with internal-combustion engines or solid oxide fuel cells (SOFCs) for plug-in hybrid electric vehicle (PHEV) applications with extended driving range. The broader/commercial impacts of this research are to provide a low cost, highly reliable electric energy storage system, which integrates with a broad spectrum of power generation systems. It includes the fast market penetration renewable energy power systems that mitigate grid transient issues, and gasoline internal-combustion engines or advanced SOFCs for PHEV with extended driving distances. The successful development and deployment of the proposed p-ZEBRA battery technology will assist the US with building critical new industry and reinstating US leadership in large-scale electric energy storages.
