PFI-TT: Development of Prototype Aqueous Energy Storage Device using Nanomaterials

这个PFI项目的更广泛的影响/商业潜力是为目前市场上的锂离子电池技术提供一种替代能源存储解决方案，使用V2O5纳米材料提供一种更安全、更稳定、更便宜的存储系统。住宅太阳能光伏系统与负担得起的电池存储相结合，越来越有可能推动现代电力供应系统的发展，同时降低温室气体排放。在过去的十年中，住宅太阳能光伏发电在全国范围内的发展已经打破了集中式电力系统的运行方式。由于太阳能电池板系统的价格在过去几年里急剧下降，一个可以离网运行的住宅太阳能电池系统仍然相对昂贵。该技术如果成功，将为住宅太阳能系统提供一种低成本、环保的基于V2O5纳米材料的水电池系统，从而为住宅太阳能系统提供一种具有成本效益的储能解决方案。因此，在安装太阳能电池板系统时所需的投资将大大减少，加速了住宅太阳能的采用。该项目是建立在PI之前成功开发用于水k离子存储的无序V2O5纳米材料的基础上的。然而，在实际操作条件下使用这种创新材料的真实尺寸储能装置尚未经过测试，这需要开发原型电池装置。拟议的项目将涉及拟议材料的扩大生产，包括使用工业级生产线设备制造和测试原型袋电池。该项目将为跨越性能差距提供一个关键的桥梁，将这一创新从实验室转移到商业规模。该项目还将利用现实的评估指标来支持设备从研究发现到商业现实的持续发展。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this PFI project is to provide an alternative energy storage solution to current lithium-ion battery technology in the marketplace, with a safer, more stable, and less expensive storage system using V2O5 nanomaterials. Residential solar photovoltaic systems combined with affordable battery storage are becoming increasingly likely to drive an evolution of modern electricity supply systems with a low-emission of greenhouse gases. In the past decade, development of the residential solar photovoltaic across the nation has disrupted the way in which centralized electricity systems operate. As solar panel system prices have fallen dramatically in the past few years, a residential solar battery system that can operate off-grid remains relatively expensive. The proposed technology, if successful, will provide a cost-effective energy storage solution for residential solar systems by offering a low-cost, environmentally benign aqueous battery system based on V2O5 nanomaterials. Thus, much less investment will be needed during installation of solar panel system, accelerating the adoption of residential solar energy. The proposed project is built on the PI's previous success on the development of disordered V2O5 nanomaterials for aqueous K-ion storage. However, the real-size energy storage devices using such innovative materials under practical operational conditions has not been tested, which requires the development of prototype battery devices. The proposed project will involve the scale-up production of the proposed materials, including the fabricating and testing of the prototype pouch cells using industrial-level line equipment. This project will provide a critical bridge across the performance gap to move this innovation from the lab to commercial scale. This project will also utilize realistic assessment metrics to support the continued development of the device from research discovery toward commercial reality.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
