Li-ion/Na-ion Batteries & Battery Thermal Management System
July 12, 2022
Lithium-ion batteries are rechargeable batteries known for their high energy density, long lifespan, and versatility. They use lithium ions moving between an anode and cathode during charging and discharging. They are widely used in consumer electronics, electric vehicles, and energy storage applications due to their performance and adaptability. Sodium-ion batteries use sodium ions for energy storage instead of lithium ions. They are being developed as a more cost-effective alternative to lithium-ion batteries due to the abundance and lower cost of sodium. Battery Thermal Management Systems (BTMS) regulate battery temperature to optimize performance, prevent overheating, and ensure safety. They use cooling or heating systems, sensors, and controllers to maintain the ideal temperature range, crucial for battery lifespan and efficiency.
Aqueous Batteries
December 1, 2022
Aqueous batteries, leveraging water-based electrolytes, emerge as favourable alternatives to lithium-ion batteries (LIBs) for large-scale applications, offering safety, productivity, and environmental advantages. Their resistance to oxygen and moisture streamlines assembly, while rapid reaction rates ensure consistent performance. Zn-based aqueous batteries demonstrate potential with cycling stability and energy density. Al-ion batteries, with low cost and enhanced safety, indicate a significant shift in battery technology towards safer, efficient solutions.
Beyond Li-ion Battery
December 1, 2022
Lithium-Sulfur batteries boast high theoretical energy density, surpassing lithium-ion counterparts, yet face challenges like polysulfide dissolution, limiting cycle life. Solid-state batteries, with solid electrolytes, offer enhanced safety and stability, promising higher energy density and mitigated risks. Metal-air batteries, leveraging reactive metal anodes and atmospheric oxygen, promise high energy density but face hurdles like electrolyte stability. Ongoing research aims to address these challenges for clean energy storage solutions.
Supercapacitor & Hybrid Capacitor
July 26, 2023
Supercapacitors store electrical energy electrostatically at the electrolyte-electrode interface, enabling rapid charge and discharge cycles. With high power density and long cycle life, they suit applications like hybrid vehicles. Hybrid capacitors merge supercapacitor’s rapid capabilities with batteries’ energy density, offering a balance between power density and energy storage. They find use in electric vehicles, portable electronics, and renewable energy systems, showcasing versatility in various applications.
Electrocatalysis
July 26, 2022
Electrocatalysis research for H2 production and CO2 reduction focuses on sustainable energy generation and carbon capture. Exploring cost-effective alternatives like transition metal chalcogenides, and MOF-derived materials enhances H2 production efficiency. Similarly, optimization of copper-based catalysts including LDHs, MOFs, and single-atom catalysts ensures efficient CO2 reduction. This innovative research drives clean energy technologies vital for climate change.
Hydrogen Storage
July 26, 2022
Our primary focus is metal hydride storage, crucial for addressing hydrogen storage challenges, especially in transportation. While traditional hydrides excel in volume storage, weight efficiency is a concern. Tailored chemistry enhances metal hydrides' kinetics and reversibility, ensuring efficient and safe storage. Additionally, we're actively involved in reactor design, reinforcing our commitment to comprehensive solutions for hydrogen utilization in transportation and beyond.
