This Small Business Innovation Research (SBIR) Phase II project introduces a non-flammable and affordable stationary energy storage solution. Renewable energy generation has significantly increased over the past decade; however, in order for renewable electricity to be fully utilized along with demand and without curtailment, accompanying energy storage is a necessity. Storage capacity is currently lacking and must catch up with renewable generation to ensure a stable and clean grid. Current state-of-the-art lithium-ion storage solutions remain expensive, hazardous, and subject to global supply chain constraints. The technology involved in this project halves the cost of production compared to lithium-ion, is non-flammable, and utilizes abundant, domestically sourced materials. Advancing the technology in this project will open up new energy storage market opportunities, lower the barrier to adoption for energy storage, eliminate the risk of battery fires, and maximize the usage of renewable energy.This Small Business Innovation Research Phase II project develops and demonstrates a new battery in the commercially-relevant amp-hour scale, bringing it from the lab to market. Demonstrating its properties at this scale, namely its energy density, cost, manufacturability, electrochemical properties, and non-flammability, will provide crucial technology and manufacturing validation for the stationary energy storage space. Widespread adoption of this technology will bring about peak power reduction, energy cost reductions, reduced frequency of service interruptions and lower overall greenhouse gas emissions. The Phase I research efforts have successfully demonstrated the feasibility and stability of the chemistry, and the Phase II project will develop an Amp hour (Ah)-level commercially relevant cell product for third party testing and customer validation, as well as for the performance of tests to meet regulatory standards, such as UL 9540A for battery systems. New, safe energy storage technologies are necessary to meet increasing global energy demands, stabilize the grid, and accelerate further renewable energy generation.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.

该小型企业创新研究 (SBIR) 第二阶段项目引入了一种不易燃且经济实惠的固定储能解决方案。过去十年，可再生能源发电显着增加；然而，为了使可再生电力能够根据需求得到充分利用且不限电，配套的储能是必要的。目前存储容量不足，必须赶上可再生能源发电，以确保稳定和清洁的电网。目前最先进的锂离子存储解决方案仍然昂贵、危险，并且受到全球供应链的限制。该项目涉及的技术与锂离子电池相比，生产成本降低一半，不易燃，并利用丰富的国内材料。推进该项目中的技术将开辟新的能源存储市场机会，降低采用能源存储的障碍，消除电池火灾的风险，并最大限度地利用可再生能源。该小型企业创新研究第二阶段项目开发并展示了一种具有商业相关安培小时规模的新型电池，将其从实验室推向市场。在这种规模上展示其特性，即能量密度、成本、可制造性、电化学特性和不可燃性，将为固定储能空间提供关键的技术和制造验证。这项技术的广泛采用将带来峰值功率降低、能源成本降低、服务中断频率减少以及温室气体总体排放量降低。第一阶段的研究工作已成功证明了化学的可行性和稳定性，第二阶段的项目将开发安培小时 (Ah) 级的商业相关电池产品，用于第三方测试和客户验证，以及性能进行测试以满足监管标准，例如电池系统的 UL 9540A。新的、安全的储能技术对于满足日益增长的全球能源需求、稳定电网并加速进一步的可再生能源发电是必要的。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响审查进行评估，被认为值得支持标准。
