Lithium-ion battery (LIB) separators

The separator is one of the four main components (cathode, anode, electrolyte, and separator) that make up the batteries (LIBs) for electric vehicles (EV/HEV/PHEV).
As a result of their growing popularity, electric vehicles are contributing to a reduction in CO2 during driving, compared with gasoline vehicles. Improving the battery performance (extending range and ensuring safety) is essential to the popularization of electric vehicles, and our development of separator technology is playing a part in this.
S-SBR synthetic rubber for fuel-efficient tires
S-SBR is used for the tread (the part in contact with the road) on passenger vehicle tires. Based on the development of original technology, it balances low fuel consumption and braking performance of tires at a high level, contributing to dramatically increasing the fuel efficiency of automobiles.

Ion-exchange membrane process for salt electrolysis
Caustic soda and chlorine are manufactured through the electrolysis of brine. The methods of electrolysis are the mercury process, the diaphragm process and the ion-exchange membrane process. The ion-exchange process is an environmentally-friendly method that does not use mercury or asbestos. Asahi Kasei is the only manufacturer in the world that manufactures and sells ion-exchange membranes, electrolytic cells, and electrodes, and boasts the top share of the global market. We have engaged in continual development to enable electrolysis using even less electricity, and our latest ion-exchange membrane grade has the lowest power consumption (compared with Asahi Kasei products: approximately 2% less than the current grade).

Xyron™ lightweight resin
(Electric vehicle battery module materials)
Xyron™, a type of engineering plastic, is an environmentally-friendly material with non-halogen flame retardance and reduction of resin usage due to its low specific gravity. Its properties also include dimensional precision, mechanical strength, and resistance to electrolyte solution. Widely used for electric vehicle battery packs and modules, it has played a major role in the spread of electric vehicles. GOAL 7: AFFORDABLE AND CLEAN ENERGYGOAL 13: CLIMATE ACTION
Hebel Haus™

Hebel Maison™
Long Life Homes and Net Zero Energy Houses: Compared with regular housing, our homes contribute to reduction of CO2 during manufacture of all components and construction by meeting the standards for Net Zero Energy Houses, which balance household energy usage at zero or lower through power generation, advanced insulation, and energy conservation, and providing Long Life Home products with a basic structural life of at least 60 years.

Manufacturing process for acrylonitrile
Acrylonitrile, which is the raw material for ABS resin and acrylic fiber, is manufactured by making propylene (or propane) react with ammonia using a catalyst.
Asahi Kasei has continually developed catalysts that enable the efficient manufacture of acrylonitrile from less raw materials.
Asahi Kasei's catalysts can not only reduce raw material consumption compared with manufacturing acrylonitrile using other, ordinary catalysts (in the model case) but can also reduce emissions of by-products, particularly CO2, and the CO2 emissions associated with waste processing. These catalysts, therefore, make a significant contribution to the manufacture of acrylonitrile with a low environmental impact.
