Overview of Facilities

Glove boxes for all-solid-state battery fabrication

Uniquely able to perform the entire process of all-solid-state battery fabrication in an environment without exposure to the atmosphere. They enable thin-film metal sputtering and most material evaluations, such as mechanical property evaluations.

Sulfide-compatible scanning electron microscope

Uniquely able to observe sulfides, and allows observations to be conducted in a glove box without exposure to the atmosphere.

X-ray diffractometer

Uniquely able to conduct X-ray diffraction measurement of battery materials using a dedicated measurement cell without exposure to the atmosphere in a glove box.

Machine material test apparatus

Enables evaluation of the powder consolidation characteristics of battery materials that are unstable in the atmosphere and the mechanical properties of small specimens.

Compositing equipment

Powder processing equipment for dry compositing of cathode particles and solid electrolyte particles used in all-solid-state batteries without exposure to the atmosphere.

Precision powder mixing equipment

Dry mixing equipment for precise mixing of raw materials for fine powders for all-solid-state batteries with strong adhesion and cohesion properties, without exposure to the atmosphere.

Continuous heating biaxial kneading equipment

Continuous type equipment capable of composite processing of powders for all-solid-state batteries while heating, without exposure to the atmosphere.

Transmission electron microscope

Enables acquisition of high-resolution images with a spatial resolution of 0.3 nm over the wide temperature range of −170 °C to 400 °C. It is also equipped with a hollow cone dark-field image acquisition function, enabling multi-scale microstructure observations.

Mössbauer spectrometer

Uniquely able to conduct Mössbauer spectroscopy measurements without exposure to the atmosphere for materials that are unstable in the atmosphere or electrode materials that have been dismantled in a glove box. Information can be obtained about the state of iron and tin atoms in the material.

Laser Raman microscope

Enables Raman microscopic observation of battery materials by using a dedicated observation cell without exposure to the atmosphere.

Nuclear magnetic resonator

Enables nuclear magnetic resonance (NMR) measurements on battery materials that are unstable in the atmosphere, without exposure to the atmosphere in a glove box.

Electron beam microanalyzer

Uniquely able to introduce samples from the glove box without exposure to the atmosphere, and perform microstructural observation and elemental analysis of microscopic regions. In particular, the attached soft X-ray emission spectrometer is effective for detection and state analysis of light elements.
