SBIR Phase II: Planar ZEBRA Battery Development

这个小型企业创新研究第二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，使用夹在液态钠和氯化镍盐之间的钠离子导电β-氧化铝固体电解液(钠基)(p-斑马电池)。商用的钠-贝塔电池都是由壁厚超过2毫米的基管构成，以保持电池的机械完整性，从而导致相对较低的比能量密度和较大的热量块，从而抑制快速热循环。该计划的主要目标是通过开发具有薄平面架构的先进电池来克服最先进的钠-贝塔电池技术的局限性。具有高强度和高耐潮、抗二氧化碳侵蚀的高性能钠基盘将采用MSRI？S专利气相工艺开发和制造。独特的电池设计加上先进的密封技术开发和降级缓解实施，将使p-Zebra电池集成和操作灵活性适合于具有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)。它还可以与内燃机或固体氧化物燃料电池进行热集成，用于插电式混合动力汽车(PHEV)应用，并扩大行驶里程。该项目的更广泛影响/商业潜力是提供一种低成本、高可靠性的电能存储系统，该系统集成了广泛的发电系统。它包括可再生能源电力系统的快速市场渗透，以缓解电网暂态和国家能源依赖问题，以及汽油内燃机或用于延长行驶距离的PHEV的先进固体氧化物燃料电池。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系统方面的领导地位。

This Small Business Innovation Research Phase II project is to develop a planar, highly compact, sodium-beta rechargeable battery using sodium-ion conducting beta?- alumina solid electrolyte (Na-BASE) sandwiched between liquid sodium and nickel chloride-based salt, (a p-ZEBRA battery). The commercially available sodium-beta batteries are all constructed with BASE tubes having wall thickness of over 2 millimeters to maintain the battery mechanical integrity, thus leading to relatively low specific energy densities and large thermal masses that inhibit fast thermal cycling. The primary objective of this program is to overcome the limitations of the state-of-the-art sodium- beta battery technologies by the development of an advanced battery with a thin planar architecture. High performance Na-BASE discs possessing high strength and high resistance to moisture and CO2 attack will be developed and manufactured using the MSRI?s patented vapor phase process. A unique battery design accompanying an advanced sealing technology development and degradation mitigation implementation will enable the p-ZEBRA battery integration and operation flexibility suitable for intermittent renewable energy storage applications (wind, solar power and geothermal) with high round-trip efficiencies. It also enables thermal integration with internal- combustion engines or solid oxide fuel cells for plug-in hybrid electric vehicle (PHEV) applications with extended driving range.The broader impact/commercial potential of this project is to provide a low cost, highly reliable electrical energy storage system, which integrates a broad spectrum of power generation systems. It includes fast market penetration of renewable energy power systems that mitigate issues of grid transient and national energy dependency, and gasoline internal-combustion engines or advanced solid oxide fuel cells for PHEVs with extended driving distances. The successful development and deployment of the proposed p-ZEBRA battery technology will assist the US in building critical new industry and reinstating US leadership in large-scale electrical energy storage systems.
