The lab searches for materials for next-generation batteries using experimental robots and data science.
AboutAbout the lab
Finding battery materials with robots and data.
Matsuda Lab researches the search for electrochemical materials using automated experimental robots and data science.
Its aim is to bring high-energy-density batteries and hydrogen production by water electrolysis into practical use in society sooner.
By making experimental processes high-throughput, the lab collects large amounts of data in a short time, and applies data science methods to that data to discover new materials.
Prof. Matsuda, a Project Associate Professor, is the team leader of the Electrochemical Smart Lab Team at the National Institute for Materials Science (NIMS), and the lab accepts doctoral students through a cooperative graduate school arrangement.
Key terms
- Electrolyte
- The liquid inside a battery through which the ions that carry electric charge move back and forth
- Lithium-air battery
- A battery that uses oxygen from the air for its positive electrode. It is expected to reach a higher energy density than lithium-ion batteries
- High-throughput experimentation
- An approach that automatically runs experiments under many conditions one after another to collect large amounts of data in a short time
ResearchResearch themes
In the NIMS Electrochemical Smart Lab Team led by Prof. Matsuda, the lab uses automated experimental robots to make experiments high-throughput and collect large amounts of experimental data in a short time. By applying data science methods to that data, it aims to find innovative electrochemical materials as quickly as possible.
*Illustrative imageMaterials Discovery with an Electrochemical Smart Lab
Unlike crystalline solid materials, non-crystalline materials such as battery electrodes and electrolytes lack the property data needed to search for them with data science. The lab therefore developed its own materials discovery method that combines automated electrochemical experimental robots with data science, and demonstrated its effectiveness on electrolytes for batteries. It is now extending the method to materials for water electrolysis and plating.
*Illustrative imageDegradation Mechanisms in Next-Generation Batteries
The energy density of lithium-ion batteries is thought to be limited to about 300 Wh/kg. Targeting lithium-air batteries and lithium metal batteries, the lab investigates the degradation mechanisms specific to high-energy-density cells and develops new materials that can be used repeatedly over a long time. It has also succeeded in operating a 500 Wh/kg-class lithium-air battery cell stably at room temperature.
