4. Battery safety inspection


         Due to the widespread use of various electrical and electronic devices, the pursuit of high energy density in lithium-ion batteries highlights the urgent need to ensure their safe and reliable operation. However, both individual batteries and battery packs face significant challenges in improving safety due to their complex structural composition and chemical reaction processes. Key factors directly related to battery safety include electrode material fracture, SEI formation, and structural changes induced by stress. Particularly, volume changes in electrode active materials during electrochemical cycling are a major cause of battery failure and danger. Therefore, accurately monitoring internal stress caused by volume changes in electrode active materials is more effective in providing early warning signals for thermal runaway in lithium-ion battery systems compared to external temperature monitoring. Our research group has developed a new type of internal pressure sensor for batteries using special carbon nanotube arrays, capable of detecting changes in internal stress during battery cycling.

2. Strong adhesion for underwater environments


       Underwater adhesive materials are widely used in underwater basic energy devices, underwater monitoring, and underwater robots. However, the nanoscale hydration layer formed by water molecules on the surface of objects hinders the contact between adhesive materials and substrates, making underwater adhesion challenging. Carbon nanomaterials, including carbon nanotubes, graphene, and carbon nanoparticles, are key to improving underwater adhesion performance due to their excellent mechanical strength and chemical stability. Our research group has designed and constructed underwater adhesive materials with a multi-scale pore structure, which includes vertically aligned submicron-sized pores, forming a complete network through nanopores on the pore walls. Under pre-pressure, these adhesive materials absorb and lock water from the hydration layer into nanopores through submicron-sized vertical channels, achieving super-strong adhesive force through internal and external pressure differences.

3. Integrated medical device for human health


         The integration of diagnosis and treatment is a new type of biomedical technology that organically combines the diagnosis and treatment of diseases. The rapid development of integrated devices for diagnosis and treatment has changed the traditional medical model. Because the integration of diagnosis and treatment integrates the functions of diagnosis and treatment, compared with There are obvious advantages over a single model.It has great potential in refined patient classification and personalized medicine, drug delivery, and implementation of drug feedback.For example, measure various health-related signs such as body movement, muscle movement, pulse, heart and breathing rate, body temperature, skin and respiratory humidity, electrophysiological signals such as electrocardiogram(ECG), electromyography(EMG), brain Electrograms (EEGs), electroophthalmograms (EOGs), and electrogastrograms (EGGs), as well as biochemical components (such as metabolites and electrolytes), and process the information to give comprehensive treatment recommendations.Compared with other candidate materials, advanced carbon nanomaterials such as carbon nanotubes (CNTs), graphene (including graphene oxide (GO) and reduced graphene oxide (rGO)) and other carbon materials (such as graphite, carbon black and Carbon materials derived from natural biomaterials) have unique advantages such as good electrical conductivity, high chemical and thermal stability, low toxicity, and easy functionalization, which make them have great application potential in integrated medical devices.

1. Underwater low-frequency sensor


      Underwater low-frequency detection devices and systems solve the limitation of detection mechanisms on the frequency range of underwater detection from the source, achieving underwater detection capabilities across a broad frequency domain from 0.1 to 50,000 Hz and pressure detection capabilities from 190 mPa to 50 kPa. The detection frequency and pressure range have been expanded by 2 to 3 orders of magnitude compared to the most advanced underwater detection technologies currently available. Additionally, the energy generated by low-frequency piezoelectric materials is 6 to 9 orders of magnitude greater than the PZT-507 materials used by the U.S. military. This technology has unique advantages in the detection domain of quiet submarines and is expected to be applied in national defense-related fields, which is of significant importance to national maritime security. Relevant achievements have been patented under multiple patents, including “Self-Powered Pressure Sensor Based on Electrochemical Principles and Its Preparation Method,” and have completed patent layout in related fields. The related devices have undergone third-party certification testing at institutions such as China Electronics Technology Group Corporation (CETC) 23rd Research Institute, Puget Sound Marine, and Northwestern Polytechnical University.

5. Extreme low temperature energy storage device


        With the advancement of technology and the growing demand for energy, energy storage technologies under extreme low temperatures have become a research hotspot. Extreme low-temperature environments, such as those in polar exploration, deep space exploration, and liquid nitrogen cooling technologies, require energy storage devices to operate stably under harsh temperature conditions. Traditional energy storage devices often exhibit performance degradation and shortened lifespan under extreme low temperatures. Therefore, developing high-performance energy storage devices for extreme low temperatures has significant practical implications and application prospects. This research aims to design and develop energy storage devices that can operate efficiently and stably under extreme low temperatures. Starting from key scientific issues, we design new energy storage materials suitable for extreme low-temperature environments, and prepare energy storage devices with high energy and power densities that can still operate stably in such conditions. By combining advanced experimental equipment and theoretical models, we aim to overcome current technological bottlenecks and achieve innovative development in extreme low-temperature energy storage devices.
