AboutAbout the lab
Supporting renewable energy with nanotechnology
The Homma Lab conducts research that uses nanotechnology to pioneer renewable energy technologies.
The core of its research is the development of processes with low environmental impact and of nanomaterials with useful functions.
Building on this, the lab aims to create energy devices, from carbon dioxide conversion to next-generation secondary batteries, capacitors, and fuel cells.
It is based at the Institute of Multidisciplinary Research for Advanced Materials and was established in April 2010.
Key terms
- Nanomaterials
- Materials made of very small particles or layers roughly 1 to 100 nanometers (one billionth of a meter) in size
- Secondary battery
- A battery that can be recharged and used many times. The lithium-ion battery is the best-known example
- Electrocatalyst
- A substance placed on an electrode surface that makes chemical reactions using electricity proceed more easily

ResearchResearch themes
To build sustainable technologies for the Earth and a low-carbon society, the lab is pioneering the frontier of renewable energy technologies based on nanotechnology. Grounded in advanced materials science, such as single-atomic-layer materials, nanoparticles, and nanoporous materials, it studies energy devices including high-capacity, high-power batteries, fuel cells, and solar cells.
*Illustrative imageNanocrystalline Active Materials and Next-Generation Secondary Batteries
To make batteries that go far beyond today's lithium-ion batteries, nano-sized active materials with low resistance and easy ion movement are needed. The lab devises synthesis processes to make materials whose particle size and shape are precisely controlled, and applies them to electrodes for magnesium-ion batteries and aqueous batteries.
*Illustrative imageDesign of Highly Active Electrocatalysts
The catalysts placed on electrodes determine the efficiency of energy-conversion reactions. Focusing on the reaction that electrolyzes water into hydrogen and oxygen, and on reactions that make fuels and chemical feedstocks from carbon dioxide, the lab develops materials such as metal oxides, metal nanoparticles, and inorganic carbon.
*Illustrative imageMicro Electrochemical Devices
Small, high-capacity batteries that can be built into many kinds of devices are in demand. Using nanomaterial synthesis and techniques for making microelectrodes, the lab is working on materials that can be applied to ultra-small lithium secondary batteries, fuel cells, electrochemical capacitors, and ingestible sensors.
