ABSTRACT：Rechargeable batteries are one of the key elements in promoting renewable energy utilization and transportation electrification, which are critical for carbon neutralization. Sulfur is an earth abundant element that is cheap and can offer high redox capacity, and therefore can have great potential to serve as an electrode material for rechargeable batteries. This talk summarizes our research progress on (1) sulfur cathode design strategies for lithium-sulfur battery, (2) high-performance electrolyte designing principles for lithium-sulfur batteries, and (3) establishment of low-cost and highly safe aluminum-sulfur battery based on molten salt electrolytes. The emphasis is on the foundational chemical principles for designing high-performance sulfur batteries, strategies to tune the chemical reactions and the materials approaches to achieve such strategies, and examples of how to establish high-performance sulfur batteries.

可充电电池是支持清洁能源高效利用及交通电气化的重要一环，这于碳中和目标至关重要。硫是一种地壳储量极为丰富的元素，廉价且能提供较高的氧化还原容量，因此是极具前景的电池电极材料。本次报告将总结我们在三个方面的研究（1）锂硫电池的硫正极设计策略，（2）锂硫电池的高性能电解液设计，（3）低成本、高安全铝硫电池的构筑。本报告将重点介绍高性能硫基电池的底层化学设计原则，调节硫电化学反应路径的策略以及实现该策略的材料设计准则，并将举例说明最终如何实现高性能硫基电池。

ABSTRACT：The rising research interest in personalized medicine promises to revolutionize traditional medical practices. This presents a tremendous opportunity for developing wearable devices toward predictive analytics and treatment. In this talk, I will introduce our efforts in developing sweat biosensors for non-invasive molecular analysis. Such wearables can autonomously access sweat across activities and continuously measure a broad spectrum of analytes including metabolites, nutrients, hormones, and drugs. Laser-engraving and inkjet printing are used to manufacture these nanomaterials-based biosensors at large scale and low cost. The clinical value of our wearable systems is evaluated through human studies toward nutritional monitoring, disease diagnosis, mental health assessment, and drug personalization. I will also discuss our research progress on energy harvesting from the body fluids and human motion to realize battery-free wireless wearable sensing. These wearable technologies could open the door to a wide range of personalized monitoring, diagnostic, and therapeutic applications.

基于柔性生物电子技术与功能材料器件的深入研究，个性化医疗健康领域得以快速发展，为病情诊断与术后治疗相关的可穿戴电子、柔性生物传感带来了令人振奋的研究契机。在这里，我将介绍我们在研发全集成皮肤界面的柔性生物传感器方面的相关工作，针对汗液中各类生物标志物，包括代谢物、电解质、激素、药物以及其他各类小分子等，进行了非侵入式的连续准确监测。利用激光加工和喷墨打印，我们可以实现大批量低成本的基于各种纳米材料的可穿戴传感器的制备。通过健康人群与病患群体的临床医学研究，在生理信息监测、心理健康、疾病诊断预警与药物输运等方面，对柔性生物传感器进行了可行性评估。在此基础上，我将进一步展示我们在实现自供能去电池化电子皮肤上的最新进展。这些可穿戴汗液生物传感平台的搭建，为实时监测-原位诊断-精准治疗的个性化医疗健康领域带来了全新的发展思路。
