Carbon – Activated carbon for electrodes of energy storage devices (supercapacitors, etc.) MAXSORB – Kansai Coke and Chemicals Company Limited


High-performance activated carbon MAXSORB has become synonymous with electrode materials for high-capacity capacitors due to its characteristic high specific surface area and active point.

In addition, it is expected to demonstrate high performance not only in capacitors but also in electrode materials for next-generation batteries.

Description

MAXSORB is a high-performance activated carbon produced by the alkaline activation method and is synonymous with electrode materials for high-capacity capacitors (electric double-layer capacitors, super capacitors, lithium ion capacitors, etc.) due to its higher specific surface area and greater amount of activated carbon than general steam-activated carbon. It has also become a synonym for electrode materials for high-capacity capacitors (electric double layer capacitors, super capacitors, lithium ion capacitors, etc.).
It is also expected to demonstrate high performance as an electrode material for next-generation energy storage devices other than capacitors (mainly lithium sulfur batteries and all-solid-state batteries).

Innovating for Industry and Society

Founded in 1956 as a joint venture between Mitsubishi Chemical Industries, Kobe Steel, and Amagasaki Steel, Kansai Coke and Chemicals Company, Limited has been a cornerstone in supporting Japan’s steel industry. We specialize in the production of high-quality coke for steel-making, fuel gas, and a variety of chemical products. While these products are not used directly by consumers, they serve as the essential raw materials behind countless everyday goods, contributing to people’s daily lives.

OUR MISSION

Our management philosophy revolves around three core principles: “Treat people as assets, treat nature as an asset, and create new value.” We aim to foster a supportive work environment, protect the natural resources of the Earth, and create innovative products that meet the demands of a changing world. Our current focus includes not only coke and chemical products but also new ventures in carbon and energy chemistry, such as manufacturing electrode materials for electric double-layer capacitors, precision cleaning equipment for semiconductors and solar cells, and conducting environmental and material analyses, including VOC assessments.

CORE BUSINESS

  • Coke Making: Using advanced, environmentally friendly technologies, we produce high-quality coke for steel-making, optimizing resource use and minimizing environmental impact. Our processes include dust control, water purification, and energy recycling systems to ensure sustainable operations.
  • Gas Refining: Our expertise in gas refining allows us to recover valuable by-products, including coal tar, liquid ammonia, crude light oil, and sulfuric acid. These products are critical for industries such as environmental conservation, plastics manufacturing, and energy storage.

TECHNOLOGICAL INNOVATION

Leveraging our deep knowledge of carbon and energy chemistry, Kansai Coke and Chemicals is committed to driving innovation. We are actively engaged in research and development to improve product quality, enhance energy efficiency, and reduce environmental impact. Our capabilities extend to high-tech sectors, including electrode materials for energy storage devices, and precision cleaning technologies for semiconductors and solar cell manufacturing.

COMMITMENT TO SOCIETY

We believe that safety, environmental stewardship, and the creation of new value are the foundations of a trusted company. By maintaining accident-free and disaster-free operations, we ensure the safety of our employees and the communities around us, while our cutting-edge innovations contribute to both society and industry.
