能量，这对我们的生活至关重要。能源的需求越来越多地用于个人使用，工业用途，而且不论其面积如何。同时严格要求在供应能源方面深入考虑和关注环境影响。FDK将在有效，安全和可靠的能源管理领域做出全球贡献，通过积累的技术和先进的研发来满足这两个社会要求。

FDK成立于1950年，从锰干电池的制造和销售开始。从那时起，进行了各种电池材料实验，并根据相关材料中获得的专业知识，决定FDK将进入铁氧体业务。 FDK从铁氧体材料的发展扩展到电力变压器等电子设备。现在，我们的产品被客户用于各种领域，如工业设备，汽车电器，移动产品，通信设备和服务器产品。通过我们的电池业务，FDK提供高品质的碱性电池，用于火警的专用锂电池以及高耐久性的镍氢电池，可以快速充电重复使用。 FDK继续投资电池材料的研发。FDK的电池存在于许多生活场景中，从工业现场到家庭应用。 FDK还参与电力存储系统，因为协同产品将电池和电子技术以及传感器设备相结合，不断响应物联网并大幅发展。

由于电力是我们生活中必不可少的能源，能源管理，如何创造，储存和明智地使用电力，是我们社会中持续存在的挑战。 FDK将继续提供技术和产品，以支持应对这些挑战的最终解决方案。

FDK将努力从材料中汲取无限潜力，同时迅速适应不断变化的商业环境。 FDK集团通过“One FDK”作为“智能能源经理”为全球客户提供服务和价值，通过结合电池技术，电路技术和电力电子技术的优势，为社会提供有效利用电能的技术。

The Energy, which is essential and important in our lives. The demand of Energy is increasing more and more for the individual use, industrial use, and regardless of the area. At the same time it is strictly requested to consider and to care the environmental influence deeply in supplying energy.
FDK will globally contribute in the fields of effective, safe and reliable energy management to respond to these two social requirements by the accumulated technology and advanced research and development.

Founded in 1950, FDK started from the manufacture and sales of manganese dry batteries. From that time, various experiments with battery materials were conducted, and from the expertise gained in the related materials, it was decided that FDK would entered the ferrite business. FDK expanded from the development of ferrite materials to electronic devices such as power transformers. Now, our products are used by customers in various fields such as industrial equipment, automotive appliance, mobile products, communications equipment and server products. With our battery business, FDK offers high quality alkaline batteries, specialized lithium batteries used in fire alarms as well as high durability nickel-metal hydride batteries, which can be used repeatedly with rapid charging. FDK continues to invest in the research and development of battery materials. Our batteries are found in many life scenes, from industrial sites to household applications. FDK also engages in power storage systems as the synergy products combine the battery and electronic technology as well as sensor device responding to IoT continually and dramatically evolving.

As electricity is an essential energy in our lives, energy management, how to create it, store it and use it wisely, are on-going challenges in our society. FDK will continue to provide technologies and products in our quest to support the ultimate solutions to these challenges.

FDK will strive to pull the infinite potential power from materials while adapting rapidly to the ever-changing business environment. FDK Group provide the service and value to customers by “One FDK” as “Smart Energy Manager” globally to contribute to society with technology that efficiently uses electric energy by combining our strength of battery technology, circuit technology and power electronics technology.
