Synthesis of nanomaterials

for rechargeable battery

systems

Without a magnetic field With a magnetic field

We are researching practical

thermodynamics and electrochemistry, which

are useful in the synthesis of various

materials. Learning through a series of

laboratory seminar is provided.

For example, as shown on the left,

synthesis processes of metal and oxide

nanomaterials are designed based on a

potential-pH diagram.

Liquid-phase synthesis of metal and oxide nanomaterials

Formation of solid electrolyte film via electro-organic synthesis

Improvement in the charge-discharge properties of rechargeable

batteries using nanomaterials as electrode materials

The electron microscopy images on the left

show ferromagnetic metal nanowires, which

were synthesized in a process that combines

ferromagnetic nanoparticles and an external

magnetic field. Metal nanowires can be

modified into oxide nanowires. Selective

oxidation of the nanowire surface can provide

an electrode active material with electron-

conducting paths.

To develop rechargeable batteries with a electromotive force higher

than 4V, establishing a synthesis process of solid electrolyte film with a

high carrier ion and low electron conductivity is important. In this

laboratory, we are also studying the formation of a solid electrolyte film

via electro-organic synthesis.

7

By establishing a simple and low-cost synthesis process of metal and

oxide nanomaterials, we seek to develop next generation rechargeable

batteries with high charge-discharge properties.

We are seeking to synthesize electrode active materials and solid electrolyte materials,

and fabricate batteries to conduct charge-discharge tests. By learning and enjoying how

to create things, we are working to develop next generation rechargeable batteries.

High Pressure Synthesis

Our group tries to synthesize novel materials

which are not available under ambient

conditions. Our high pressure synthesis

techniques developed in collaboration with

geoscientists are beyond other materials

science research groups.

Experiments at synchrotron radiation facility SPring-8.

We especially welcome ambitious young people who want to immortalize themselves in materials science!

A novel material SrCu3Fe4O12, which was

reported by us, demonstrates a giant negative

thermal expansion (NTE). The NTE mechanism

for SrCu3Fe4O12 was found to be to "intersite

charge transfer" between Cu and Fe, being

distinguished from conventional ones. This

was extensively introduced in newspapers and

websites.

We investigate structural and physical properties

of the novel materials and evaluate their

potential.
