Preparation of Mxenes and Its Application in Lithium/Sodium Batteries


Since its discovery in 2011, MXenes have attracted great interest in the field of energy storage due to their unique combination of characteristics such as metal conductivity, hydrophilicity, large interlayer spacing, and rich surface chemical properties. The most significant characteristics of MXene are its large adjustable interlayer spacing and rich surface chemical properties, which make it different from other two-dimensional materials. We mainly discuss the synthesis and pillaring of MXene ultra-thin layers, the preparation of MXene/transition metal sulfide heterostructures through Lewis acid molten salt etching and subsequent in-situ vulcanization treatment, and their applications in lithium/sodium ion batteries.

Pressure-induced structural changes in disordered materials


Due to unique atomic packing structure, disordered materials can exhibit many excellent properties. Pressure, as a thermodynamic parameter, can turn atomic packing and consequently modify properties of materials. Here I talk about pressure-induced structural changes in disordered metallic materials. Some unique phenomena, e.g., amorphous-to-amorphous phase transition, reversible crystallization reaction, will be investigated and their origins are discussed.

Understanding the degradation mechanisms in high-energy density cathodes via synchrotron X-ray techniques


The progress in electric vehicle (EV) development has heightened the demand for lithium-ion batteries (LIBs) with enhanced energy density and extended cycle life. Within this context, the cathode material assumes a critical role in shaping the overall performance of lithium-ion batteries. To advance the development of the next generation of high-energy-density cathode materials, our research endeavors have systematically unraveled the intricacies of performance degradation mechanisms inherent in layered structure cathodes. This exploration leveraged a sophisticated combination of advanced synchrotron X-ray-based characterization techniques across multiple scales. Our investigation has been transformative, shedding light on the intrinsic correlation between stress-strain dynamics and mechanical degradation within layered cathode materials. Specifically, we discerned that the accrual of lattice strain during lithium extraction and insertion plays a significant role in inducing structural distortion and subsequent performance decay. This pioneering insight has given rise to a novel strategy for structural stress regulation, culminating in the innovative development of ultra-low strain layered cathode materials. This accomplishment is a testament to our meticulous approach to material structure design at the lattice scale, effectively mitigating inherent defects and ushering in a new era of advancements in cathode material research.

Preparation and Application of Flexible Ultrafine Titanium Dioxide Nanowire Optoelectronic Materials


Reducing the nanoscale of the catalyst can obtain a higher comparative area. When the nanoscale is less than a critical value, it will also generate a unique photon effect, thereby further improving the photoelectric performance of catalyst semiconductors. In this report, a synthesis technique was introduced for inducing the formation of TiO2 ultrafine nanowire arrays using carbon quantum dots (CQDs) with hydrothermal method. The synthesized TiO2 nanowires were grown in situ on a flexible Ti substrate. Compared with existing reports, the obtained TiO2 nanowires have made breakthroughs in geometric morphology and optoelectronic properties, and have shown good application potential in photoelectrochemical water resolution hydrogen, organic pollutant degradation, and self driven optoelectronic collaborative wastewater treatment.

Recent progress on electromechanical coupling effect in ferroelectric polymer and nanocomposites


Low-cost, light weight, flexible relaxor ferroelectric polymers and nanocomposites are a unique member in ferroelectric materials to develop flexible, wearable and biocompatible devices in acoustic sensors, transducers and actuators. In this talk, we first present our discovery of morphotropic phase boundary-like behavior in ferroelectric copolymers which exhibits the state-of-the-art piezoelectric coefficient of -63.5 pC/N. Moreover, we reveal that the relaxor behavior of ferroelectric polymers originates from conformational disorder, which is completely different from classic perovskite relaxors typically characterized by the existence of chemical disorder. We show that chain chirality is essential to the formation of disordered helix conformation arising from local distortions of gauche torsional angles, which consequently give rise to relaxor ferroelectric properties in polymers. We are dedicated to address recent emerging advance in electro-thermal actuation in ferroelectric polymer nanocomposites which show a strain of over 8% and an output mechanical energy density of 11.3 J/cm3 at an electric field of 40 MV/m in the composite, outperforming the benchmark relaxor single-crystal ferroelectrics. The deep insights into ferroelectric polymers and nanocomposites may pave the way towards rational design of the state-of-the-art electronics and energy storage devices.
