Building a Sustainable Future with Energy Storage Technology

The ionic liquid lithium-ion battery, developed by Professor Masashi Ishikawa of the Faculty of Chemistry, Materials and Bioengineering at Kansai University (our CEO), is a new type of lithium-ion battery that overcomes the fundamental concern that batteries can catch fire.

Its high level of safety has enabled use in space operations, leading to the world’s first successful charge-discharge test in Earth orbit.

By replacing conventional electrolytes with an ionic liquid and eliminating volatile and flammable components, this battery suppresses swelling and has achieved zero fire incidents.

In space, it also eliminates the need for the robust casing required by conventional batteries.

Organic solvent-based slurry preparation and coating have long been widely used in lithium-ion battery electrode manufacturing.

We are developing cathode manufacturing technology that uses water instead of an organic solvent (NMP), with a focus on electrode manufacturing processes based on aqueous slurry and water-based binders.

This aqueous process is expected to reduce VOC emissions, simplify solvent recovery and recycling, conserve energy, and lower manufacturing costs.

However, transitioning to an aqueous process presents challenges different from conventional organic-solvent systems, including slurry dispersion, pH, viscosity and rheology, coating properties, drying characteristics, and electrode adhesion.

By optimizing material design together with slurry and electrode processes, we aim to achieve both electrode performance and productivity in an aqueous process.
