The broader impact/commercial potential of this Small Business Innovation Research Phase II project will be to stabilize and support a more robust and diverse power grid. The goal is to countervail today's stress on the grid, caused by rapidly growing electric power demand and the integration of renewable power sources. In this project, a distributed energy storage system will be developed that is robust, scalable, deployable, and price competitive. The storage system will help to improve the power quality, avoid widespread power outages, integrate renewable energy, and improve the utilization of existing grid assets. This storage system will allow utilities and system operators to reduce investments into the existing grid while simultaneously improving the service for their customers. The grid-scaled distributed energy storage market is an emerging market that is projected to growly rapidly in the coming years according to numerous studies. Among all the different storage technologies, batteries have the scalability, calendar life, cycle life, response time and low maintenance costs most suitable to the needs of distributed, power-grid-integrated energy storage. The technical objectives of this Phase II research project are to produce a significantly improved version of the existing sodium metal chloride battery and demonstrate a 4 kWh battery system. Sodium batteries were identified by Sandia National Laboratory as providing the highest technical and economic development potential for grid-scaled distributed energy storage. The main barriers to their wide-spread implementation are their considerably high production cost, their high operating temperature, and their long charge/discharge time. Na4B has developed a new electrolyte to vastly improve the ion transport and to overcome the technical limitations inherent in the existing technology. The electrolyte design, developed in this project, shows superior ion conductivity and is a basis for a prismatic sodium metal chloride electrochemical cell. These achievements allow for the production of a new generation of sodium batteries with greatly improved performance, at a much lower cost.

这个小企业创新研究第二阶段项目的更广泛的影响/商业潜力将是稳定和支持一个更强大和多样化的电网。其目标是抵消电力需求的快速增长和可再生能源的整合给电网带来的压力。在这个项目中，将开发一个分布式能源存储系统，该系统健壮、可扩展、可部署且价格具有竞争力。该储能系统将有助于改善电能质量，避免大面积停电，整合可再生能源，提高现有电网资产的利用率。该存储系统将允许公用事业公司和系统运营商减少对现有电网的投资，同时改善对客户的服务。根据众多研究，电网规模分布式储能市场是一个新兴市场，预计未来几年将快速增长。在所有不同的储能技术中，电池具有可扩展性、日历寿命、循环寿命、响应时间和低维护成本，最适合分布式、并网储能的需求。该二期研究项目的技术目标是生产现有氯化钠电池的显著改进版本，并演示一个4千瓦时的电池系统。桑迪亚国家实验室（Sandia National Laboratory）认为，钠电池为电网规模的分布式能源存储提供了最高的技术和经济发展潜力。其广泛应用的主要障碍是其相当高的生产成本、高工作温度和长充电/放电时间。Na4B开发了一种新的电解质，极大地改善了离子传输，克服了现有技术固有的技术限制。本项目开发的电解质设计具有优异的离子导电性，是柱状金属氯化钠电化学电池的基础。这些成就使得以更低的成本生产性能大大提高的新一代钠电池成为可能。
