Ion-Conductive Polymers

In ion-conductive polymers, a substance such as an alkali metal salt is dissolved in a polymer which forms the matrix. These polymers are roughly divided into two categories: pure polymer solid electrolyte and polymer gel electrolyte. The former is a complex made of a polymer backbone and alkali metal salt. In the latter, ion-conductive liquids such as electrolyte solution or ionic liquids are changed into a quasi-solid state using polymer.
When an ion-conductive polymer is used as the electrolyte in a lithium battery, it has various advantages over conventional electrolyte solution, including preventing leakage, ensuring physical reliability, suppressing abnormal runaway reactions, and otherwise improving safety and allowing greater freedom in terms of shape. In addition to lithium batteries, we are also developing applications as an electrolyte for electric double-layer capacitors and dye-sensitized solar cells.

Conductive Pastes

Conductive pastes are used in LTCC (Low Temperature Co-fired Ceramic) boards employed in applications such as mobile phones, personal digital assistants and laptop PCs. Conductive paste is comprised of metallic powder particles and fusible binder, and 30-50 micron fine lines are formed on ceramic boards.

Ceramic Materials

Binders, dispersants, lubricants and mold release agents for ceramics are used to form fine ceramics. Fine ceramics are used in applications such as automobile engines, IC substrates, sensors and mobile phones.

Ionic Liquids

Ionic liquids are compounds made of ion pairs, which generally assume the liquid state at temperatures of 100°C or less. They have no vapor pressure, and are nonflammable. Since they are highly safe and have high ion-conductivity, we are developing electrolyte applications such as lithium ion batteries and capacitors. These liquids are also attracting attention as next-generation materials in the energy device field, and as green solvents for reducing environmental impact.
