Superexcited states of NO molecule and their neutral dissociation processes have been studied both experimentally and theoretically. Neutral excited N^＊ and O^＊ atoms are detected by fluorescence spectroscopy for the NO molecule upon interaction with 800 nm intense laser radiation of duration 60 fs and intensity 0.2 Pw/cm^2. Intense laser pulse causes neutral dissociation of superexcited NO molecule by way of multiphoton excitation, which is equivalent to single photon excitation in the extreme-ultraviolet region by synchrotron radiation. Potential energy curves （PECs） are also built using the calculated superexcited state of NO^＋. In light of the PECs, direct dissociation and pre-dissociation mechanisms are proposed respectively for the neutral dissociation leading to excited fragments N^＊ and O^＊.

锂离子电池潜在的热失控风险及其可能引发的叠加效应对大型锂离子电池电源的安全设计提出了巨大挑战,因此在某些特殊应用领域,如煤矿井下爆炸性环境,大容量锂离子电池电源的使用依然存在诸多限制,难以普及。根据现有针对锂离子电池热失控行为的研究结论,在不进行充分的气体热力学和动力学分析的前提下,仅采用传统隔爆外壳对大容量锂离子电池电源进行防爆保护,存在隔爆外壳内部压力积聚的安全隐患。在分析现有研究工作的基础上,选用不同电池制造商生产的容量在72~280 A·h范围内的磷酸铁锂电池进行了热失控试验研究,全面分析了锂离子电池热失控过程中电池表面以及释放气体的温度、气体释放速度、释放气体在容器内产生的压力和释放气体的成分等相关参数。在此基础上,根据气体动力学和热力学特性,系统阐述了适用于煤矿井下爆炸性环境用可移动设备和后备电源等设备的锂离子电池电源在设计和制造过程中需要重点考虑的2个因素:①锂离子电池电源外壳内部的自由空间,②锂离子电池电源内部单体电池发生热失控事故时针对所释放气体的处理方法,并提出了必要的设计依据。本研究成果有望对爆炸性特殊环境用锂离子电池电源的防爆保护设计和安全完整性评估提供新的重要参考依据。

Charging wearable energy storage devices with bioenergy from human-bodymotions, biofluids, and body heat holds great potential to construct self-powered body-worn electronics, especially considering the ceaseless nature ofhuman metabolic activities. To bridge the gap between human-body bioen-ergy and storage of energy, wearable triboelectric/piezoelectric nanogenerators(TENGs/PENGs), biofuel cells (BFCs), thermoelectric generators (TEGs) havebeen designed to harvest energy from body-motions, biofluids, and body heat,respectively. Researchers have explored various strategies using bioenergy har-vesters to charge wearable supercapacitors and batteries to relieve or even fullyeliminate the recharging process from external power stations, thus, makingwearable electronics more sustainable, autonomous, and user friendly. In thisarticle, we review the advances in the design of sustainable energy storagedevices charged by human-body energy harvesters. The progress in multifunc-tional wearable energy storage devices that cater to the easy integration withhuman-body energy harvesters will be summarized. Then, the focus is laid onthe integrating strategies (single-cell strategy and separated-cell strategy), devicedesign, materials selection, and characteristics of different self-charging human-body energy harvesting-storage systems. Finally, the challenges that impedethe wide application of human-body energy harvesters charged supercapaci-tors/batteries and prospects will be discussed both from materials and structuraldesign aspects.

The next generation of sensors should be self-powered, maintenance-free, precise, and have wide-ranging sensing abilities. Despite extensive research and development in the field of pressure sensors, the sensitivity of most pressure sensors declines significantly at higher pressures, such that they are not able to detect a wide range of pressures with a uniformly high sensitivity. In this work, we demonstrate a single-electrode triboelectric pressure sensor, which can detect a wide range of pressures from 0.05 to 600 kPa with a high degree of sensitivity across the entire range by utilizing the synergistic effects of the piezoelectric polarization and triboelectric surface charges of self-polarized polyvinyldifluoride-trifluoroethylene （P（VDF-TrFE）） sponge. Taking into account both this wide pressure range and the sensitivity, this device exhibits the best performance relative to that of previously reported self-powered pressure sensors. This achievement facilitates wide-range pressure detection for a broad spectrum of applications, ranging from simple human touch, sensor networks, smart robotics, and sports applications, thus paving the way forward for the realization of next-generation sensing devices. Moreover, this work addresses the critical issue of saturation pressure in triboelectric nanogenerators and provides insights into the role of the surface charge on a piezoelectric polymer when used in a triboelectric nanogenerator.
