Thermal Management in Batteries
The future development of high-performance batteries that can be charged quickly and hold more power could revolutionize renewable energy technologies and eliminate emissions from electric vehicles. However, obstacles, such as increased heat production and uneven temperature distribution, not only expedite battery deterioration but also raise safety issues.
Our goal is to thoroughly examine the thermal complexities within energy storage systems. This includes conducting microscopic thermal evaluations for a better understanding of the underlying mechanisms, as well as working at the device level for combined electrochemical-thermal fine-tuning. We're determined to explore how uneven temperature distribution influences battery kinetics and thermodynamics, inaugurate methods for mapping internal battery temperatures, develop thermal diagnostic tools that can be used while the battery is operational, and advance battery thermal management through forced convection and phase transition. These initiatives are crucial in facilitating the creation of next-generation batteries that offer superior performance while ensuring safe usage.
Thermal Management in Carbon Capture, Usage and Storage (CCUS)
For effective adsorptive separation, structured adsorbents must meet criteria for mass transfer and pressure drop, as well as effectively manage heat. Our study will explore how the adsorbent's structure impacts the system's thermal activity. The main goal of this research is to evaluate the performance of alternative adsorbents by creating numerical models that predict their thermal behavior under two-step pressure swing adsorption (PSA) conditions. The results of single-step CO2 breakthrough and temperature profiles affirm the structured adsorbents' efficacy in controlling thermal effects generated in the bed under non-isothermal conditions. The outcomes work under real cyclic processes, particularly during fast cycling, consistently showed the superiority of structured adsorbents and presented them as promising options for advanced PSA units. However, the structured adsorbent's performance largely relies on its dimensions and structural specifications, which need to be optimized for each particular separation.
Here is an illustration depicting biomass waste used for carbon capture and storage. It features various materials like crop residues, wood chips, sawdust, and organic waste, showing their transformation into biochar or other carbon storage forms. The background combines agricultural, forestry, and urban settings to reflect the diverse origins and importance of biomass waste in the carbon cycle.
CryoSynthesis for Clean Energy
The single-atom catalysts (SACs) offer controllable coordination environments and exceptional atom utilization efficiency, revolutionizing the design of high-performance, sustainable catalysts. Here I share my research and development of the cryogenic synthesis method as a novel platform for discovering and manufacturing energy and environmental materials with atomic precision. I will begin with the design and demonstration of an ultra-low-temperature scalable synthesis, followed by specific research topics, including single-atom catalysts, high-entropy alloys, and amorphous metals.
