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

该PFI项目更广泛的影响/商业潜力是为市场上目前的锂离子电池技术提供替代能源存储解决方案，使用V2 O 5纳米材料提供更安全，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，减少温室气体排放。在过去的十年中，全国住宅太阳能光伏的发展已经破坏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中急剧下降，可以离网运行的住宅太阳能电池系统仍然相对昂贵。 这项技术如果成功，将通过提供基于V2 O 5纳米材料的低成本、环境友好的水性电池系统，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时所需的投资将大大减少，加速了住宅太阳能的采用。拟议的项目是建立在PI先前成功开发用于水溶液K离子存储的无序V2 O 5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实际尺寸的储能装置尚未经过测试，这需要开发原型电池装置。 拟议项目将涉及拟议材料的规模扩大生产，包括使用工业级生产线设备制造和测试原型袋式电池。该项目将提供一个跨越性能差距的关键桥梁，将这项创新从实验室推向商业规模。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发展。该奖项反映了NSF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.
