The broader impact of this Small Business Innovation Research (SBIR) Phase II project is to enhance lithium-ion battery safety in electric vehicles (EV). Battery safety is critical for EVs, and existing monitoring of temperature, voltage, and current is insufficient. This project advances a new sensor to improve safety. This Small Business Innovation Research (SBIR) Phase II project will introduce Si CS-FET-based gas sensors as an advanced safety monitoring modality for EV battery packs. Lithium-ion cells vent certain gases, indicating potential problems such as overcharging and overheating. This project will develop and optimize materials and processes for high-volume manufacturing of Si CS-FET-based gas sensors. Key outcomes will be Si CS-FETs with high sensitivity and selectivity, low-power operation, and demonstrated reliability through accelerated lifetime studies. Successful project completion will also significantly advance the field of battery monitoring sensors and the broad field of battery diagnostics.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.

小企业创新研究（SBIR）第二阶段项目的更广泛影响是提高电动汽车（EV）中锂离子电池的安全性。 电池安全性对电动汽车至关重要，现有的温度、电压和电流监测是不够的。 该项目提出了一种新的传感器，以提高安全性。该小型企业创新研究（SBIR）第二阶段项目将引入基于Si CS-FET的气体传感器，作为电动汽车电池组的先进安全监测模式。锂离子电池会排出某些气体，这表明存在过度充电和过热等潜在问题。 该项目将开发和优化用于大批量制造基于Si CS-FET的气体传感器的材料和工艺。关键成果将是具有高灵敏度和选择性、低功耗操作并通过加速寿命研究证明可靠性的Si CS-FET。 该项目的成功完成也将极大地推动电池监测传感器领域和电池诊断领域的发展。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。
