SBIR Phase I: Development of novel sensors to determine health of batteries

该项目更广泛的影响/商业潜力是改善电池健康状况并预测与电池性能相关的危险事件。这将通过促进太阳能和风能的可靠储能，以及与医疗保健相关的关键应用，对消费者安全和可持续能源发展产生重要影响。随着电池的功率密度不断增加，消费者开始看到潜在的灾难性电池故障的证据，导致火灾和爆炸。该小型企业创新研究（SBIR）第一阶段项目将验证初步结果，即传感器灵敏度，尺寸和速度足以捕捉电池特征的细微变化，这些变化表明电极，电解质和其他电池组件的SEI降解形成。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 project is to improve battery health and predicting hazardous events related to battery performance. This will have an important impact on consumer safety, sustainable energy development via promoting reliable energy storage from solar and wind power, as well as in critical applications related to healthcare. As the power density of the batteries keeps increasing, consumers start seeing evidence of potentially catastrophic battery failures, resulting in fires and explosions. This Small Business Innovation Research (SBIR) Phase I project will be to validate the preliminary results that sensor sensitivity, dimensions and speed are sufficient to capture subtle changes in the battery's signatures that are indicative of formation of SEI degradation of electrodes, electrolytes and other battery components. It will be based on ex-situ and in-situ measurements, modelling and machine learning.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.
