Contributing to Realizing the SDGs

Current lithium-ion batteries use electrolyte solution, which raises concerns about safety, battery life, and heat resistance.
We have succeeded in introducing high-performance inorganic solid electrolytes through the joint development with our long-time partner companies.
The all-solid-state battery can solve the problems of current lithium-ion batteries in terms of safety, heat resistance, and longer life, and will contribute to waste reduction and make up for labor shortage in various industrial fields by reducing maintenance work.

The operating temperature range has been improved by using materials with excellent heat resistance and our proprietary encapsulation technology. These batteries are suitable for automotive applications such as power supplies for sensors in TPMS(Tire Pressure Monitoring System). This heat-resistant CR battery will be used in advanced systems for detecting flat tires, thus contributing to the global effort to reduce traffic accidents. From the standpoint of corporate responsibility, this aligns with the goal to protect safety and security of society. Maxell boasts a *70% share of the global market for this product. 　*Based on data as of August 2023, according to Maxell research.

Although lead, a substance subject to the European RoHS Directive, is a hazardous chemical, it is exempted from use in oxygen sensors, for which no alternative technology has been established, and is used throughout the world. At Maxell, we are committed to solving social environmental issues by focusing its management resources on lead-free oxygen sensors, which are environmentally friendly products that we sell. By developing an anode that replaces lead and a weakly acidic electrolyte that is suitable for the anode, we have commercialized a long-life galvanic cell-type lead-free* oxygen sensor that is less susceptible to CO₂ and other acidic gases. By not using lead* as an anode, we are reducing the risk of soil and marine pollution and its impact on the human body. 　*It means that the lead contained in each part (homogeneous substance) constituting the product is 0.1wt% or less.

By reducing water leakage, mold growth, rusting of metal parts, and deterioration of wall and ceiling materials in buildings, waste is reduced. It also helps to improve the efficiency of air conditioning by filling in the gaps between housing components, such as around pipes leading to the interior and exterior of the building. In Southeast Asia, we are promoting the construction of houses using the tarpaulin method, and in North America, we are promoting the use of airtight materials.
By spreading the use of the tarpaulin method and airtight materials, we will not only improve the living space in the region, but also improve the skills of local contractors and consider the environment.

Increasing hygiene awareness is increasing the need for products that can remove bacteria, viruses, and odors.
Ozone has the property of decomposing the source of bacteria, viruses, and odors and returning to oxygen. The "OZONEO series " of disinfectors and deodorizers that take advantage of this characteristic of ozone are used in a variety of places, including hotel rooms and hospital examination rooms.
We will continue to support comfortable lifestyles by developing products and expanding our lineup in line with customer needs.

In recent years, responding to the plastic waste and global warming issues, there has been a growing need for environmentally friendly products and packages using fewer plastic materials.
Conventional DVD-R and CD-R products use a lot of plastic materials for the plastic case and packaging to store the disc. The NEW Packaging Design uses a paper sleeve instead of a plastic case for the package, thereby reducing amount of plastic materials used and making the product to be more environmentally friendly.
Comparing with conventional plastic cases, plastic usage has been reduced by 95% for 10-disc packs and 98% for 20-disc packs. For spindle case products that can store multiple discs in a stack are reduced by 69% for 10-disc packs and 78% for 50-disc packs. In addition, the discs stored in paper sleeves can save more space than conventional style.
* The terms of "plastic reduction" in this content refers to the amount of plastic used in new package comparing with the amount of plastic used in conventional products.
