Creating Shared Value (CSV); Helping to Resolve Social Issues

DENKA BLACK Li

Social Issues

  • Urgent need for the reduction of emissions of hazardous particles and greenhouse gases from automobiles through the popularization of EVs, HVs and other eco-friendly vehicles

Society’s Technological Expectations

  • Development of safer automotive secondary batteries with superior functions

DENKA BLACK Li

DENKA BLACK Li

The Denka Group’s Technological Solutions

DENKA BLACK Li is carbon black manufactured through the thermal decomposition of acetylene gas. Boasting a unique structure, the product is used as a conductive material in lithium ion secondary batteries (LiBs).

The most prominent features of DENKA BLACK Li are its chain-like structure and extreme purity. Consisting of fine carbon particles connected in a series like a chain, even a tiny amount of DENKA BLACK Li confers high electric conductivity. Moreover, this product boasts extreme purity as we have eradicated the metallic foreign matter content that commonly compromises battery safety, making it optimal for producing reliable cells.

To ensure the supply of safe and highly functional conductive materials for LiB applications, we launched a dedicated production facility at the Chiba Plant that aims to ensure the most thorough possible eradication of foreign matter content from our output. DENKA BLACK Li is now contributing to the popularization of eco-friendly vehicles.

DENKA RENOTEC

Social Issues

  • An aging social infrastructure due to concrete degradation and emerging as problems ranging from cracking and surface delamination and the development of internal defects to salt damage and neutralization, all of which now plague roads, bridges, tunnels and other structures built during Japan’s high economic growth period, poses the risk of potential disaster

Society’s Technological Expectations

  • Safe and cost-effective repair technologies that require shorter periods to apply and that ensure long-lasting endurance by employing the diagnosis of structure degradation using non-destructive inspection methods (infrared light, supersonic, etc.) and broad-view inspections (such as those using drones, etc.)

DENKA RENOTEC

DENKA RENOTEC

The Denka Group’s Technological Solutions

  • We provide solutions to repair aged concrete structures that have surface delamination due to cracking or internal damage. Our solutions include injecting resins with superior hardening properties and applying mortar with superior waterproof properties. Moreover, with an eye to enhancing the life cycle costs of structures, we develop and employ cutting-edge materials and technologies that ensure long-lasting repair effectiveness.
  • Concrete durability can be compromised by such causes as salt damage and neutralization due to acid rain. We perform non-destructive inspections to assess and analyze the external and internal soundness of concrete, detecting the causes of degradation and identifying optimal repair methods. One such method is the DENKA TECHNOCRETE System, which is capable of restoring the strength of aged structures through electrochemical technologies. In these ways, we are helping maintain the soundness of social infrastructure.

Silicon Nitride and SN Plate

Social Issues

  • A need to popularize HEVs and EVs in order to curb vehicle emissions
  • Demand for HEVs and EVs with greater energy efficiency

Society’s Technological Expectations

  • Thermal solutions for facilitating the weight reduction and miniaturization of ECUs for motor control

DENKA SN PLATE

DENKA SN PLATE

The Denka Group’s Technological Solutions

DENKA SN PLATE, a silicon nitride-based substrate, boasts superior thermal conductivity as well as high strength and reliability. It is used as a thermal conductive substrate for the power modules used in inverters installed in HEV and EV motor control units, providing protection from heat degradation and ensuring that performance is maintained while prolonging durability.

DENKA Thermosheet Special BOPS

Social Issues

  • Growing concerns over food safety
  • A growing need for quick and easy cooking
  • Aging of society and an increase in households in which families rarely eat together

Society’s Technological Expectations

  • Highly transparent containers that allow consumers to view content
  • Heat-resistant containers with adaptability to microwave cooking as well as oil resistance
  • High-strength, lightweight containers that facilitate resource saving and CO2 reduction

DENKA BOPS

DENKA BOPS

The Denka Group’s Technological Solutions

On the back of a growing reliance on take-out food, which is usually microwaved before consumption, we are seeing increasing demand for highly functional plastic food containers with greater heat- and oil-resistant properties. In response, we developed a special BOPS, a food container sheet that incorporates a new polymer. Boasting superior resistance to heat and oil, this product is also highly transparent and lightweight, just like its conventional counterparts. Moreover, efforts are now under way to boost its heat-and oil-resistance even further.

These and other functional BOPS products will contribute to the convenience of consumers by broadening the range of foods that can be microwaved within the container.
