From batteries to artificial bone: bringing out the full power of ceramics.

AboutAbout the lab
Creating solid materials for energy and medicine.
The Functional Solid State Chemistry Lab studies the analysis, design, and synthesis of functional solid materials for energy, the environment, and medicine.
Focusing on electrochemical energy, which converts energy with high efficiency, the lab develops materials for fuel cells, lithium-ion secondary batteries, and more.
Based on crystal chemistry theory, the lab precisely analyzes and designs structures.
By synthesizing ceramics inspired by how living organisms form bone, the lab also develops materials that heal bone and microcapsules that deliver drugs.
Key terms
- Solid electrolyte
- A solid material that conducts ions inside a battery.
- Solid oxide fuel cell

ResearchResearch themes
The lab works on the analysis, design, and synthesis of functional solid materials for energy, the environment, and medicine. Its research rests on two pillars: the design and development of electrochemical energy materials, and the development of functional ceramic biomaterials.
*Illustrative imageElectrodes that charge fast and hold more
The lab develops positive and negative electrode materials that take in lithium more easily and in larger amounts. From the standpoint of battery degradation, it also uses structural analysis, for example on graphite negative electrodes, to study how structures shift to the most stable form after charging and discharging.
*Illustrative imageElectrolytes for all-solid-state batteries
For all-solid-state batteries, which pose no risk of leakage or fire, the lab develops oxide-based solid electrolytes. It found that a composite of LATP with finely dispersed LaPO4 raises lithium-ion conductivity by about three times.
*Illustrative imageElectrolytes for fuel cells
Solid oxide fuel cells, which operate at high temperatures, have high power generation efficiency and do not need expensive catalysts. The lab develops electrolytes that conduct ions well by controlling defect structures, and uses neutron diffraction to investigate the pathways ions take.
*Illustrative imageMaterials that bond with bone
Using biomimetic methods inspired by the processes of living organisms, the lab develops bone-repair materials that bond well with bone and have strength and softness suited to where they are used. Aiming at applications in orthopedics and dentistry, the work is carried out through collaboration among medicine, dentistry, and engineering.
