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.

该PFI项目的更广泛的影响/商业潜力是为市场中当前的锂离子电池技术提供替代的储能解决方案，并使用V2O5纳米材料采用更安全，更稳定且较便宜的存储系统。 住宅太阳能光伏系统与负担得起的电池存储相结合，越来越有可能通过低排放温室气体的现代电力供应系统的发展。在过去的十年中，全国住宅太阳能光伏的开发破坏了集中电力系统运行的方式。由于太阳能电池板系统的价格在过去几年中急剧下降，因此一种可以在网格中运行的住宅太阳能电池系统仍然相对昂贵。 拟议的技术，如果成功的话，将通过提供基于V2O5纳米材料的低成本，环保水性电池系统，为住宅太阳能系统提供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期间，所需的投资要少得多，从而加速了住宅太阳能的采用。拟议的项目建立在PI先前的成功基础上，该项目是在无序的V2O5纳米材料开发用于k-ion储存水的纳米材料的发展。但是，在实际操作条件下使用此类创新材料的实际尺寸储能设备尚未进行测试，这需要开发原型电池设备。 拟议的项目将涉及提议的材料的扩大生产，包括使用工业级别的线路设备制造和测试原型小袋单元。该项目将为跨性能差距提供一个关键的桥梁，以将这项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该设备从研究发现到商业现实的持续开发。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估的评估来支持的。
