Research
We are conducting research on materials used in lithium-ion batteries (LiBs) and next-generation energy storage solutions, including all-solid-state batteries.
1. Layered cathode materials (NCM, NCA)
Layered cathode materials play a central role in the advancement of high-energy lithium-ion batteries, offering a balance of capacity, stability, and scalability. Their unique crystal structures enable efficient lithium transport, making them a key platform for next-generation energy storage. Ongoing research continues to refine their performance through compositional design and structural engineering in our lab.
2. Cathode materials for all-solid-state batteries
All-solid-state batteries are emerging as a transformative technology that promises improved safety and energy density compared to conventional lithium-ion systems. By replacing flammable liquid electrolytes with solid materials, ASSBs open pathways for reliable and compact battery designs. Our goal is overcoming challenges in interfaces, conductivity, and large-scale implementation of ASSBs.
3. All-solid-state lithium sulfur batteries
Our laboratory aims to address the critical challenge of the shuttle effect in conventional lithium–sulfur batteries by developing all-solid-state lithium–sulfur systems. We focus on designing cathode and anode materials as well as stable interfaces based on solid electrolytes, with the goal of achieving both high energy density and long-term cycling stability.
4. Li-metal
Our research on lithium metal anodes explores surface coating and chemical modification strategies to suppress dendrite growth. Through these approaches, we seek practical and stable methods for the application of lithium metal.
