New Manufacturing Facility Opens in Onojo City, Fukuoka, to Produce RENERATH, a Storage Battery System Using Recycled EV Batteries—Supporting Local Circular Economy

I-PEX Inc. (Headquarters: Kyoto City, Kyoto Prefecture, Representative Director and President: Reiji Konishi, hereinafter referred to as I-PEX) has renovated the second building of Onojo Plant (hereinafter referred to as the core location) in Onojo City, Fukuoka Prefecture, and started operations in June 2025 as a production location for the RENERATH storage battery system product series, which reuses lithium-ion batteries from electric vehicles (hereinafter referred to as used EV batteries).

Prior to this, an opening ceremony was held on May 30th, inviting relevant parties.

I-PEX entered the environmental and energy solutions business (currently Energy Solutions Business) in February 2024 and began developing and selling the storage battery system RENERATH. In July of the same year, it joined the Green EV Battery Network Fukuoka (hereinafter referred to as GBNet Fukuoka)*.

As the core location for I-PEX's battery storage system, this facility will handle a series of processes for used EV batteries, from battery pack dismantling, module inspection, and storage battery assembly, and will manufacture the RENERATH battery storage system. In addition, through activities at this location, we will contribute to the realization of a decarbonized, resource-circulating society by promoting resource circulation of used EV batteries, mainly in Fukuoka Prefecture, through GBNet Fukuoka.

The opening ceremony, held on May 30, 2025, was attended by approximately 60 people, including representatives from Fukuoka Prefecture and GBNet Fukuoka member companies and organizations, as well as media representatives. The ceremony began with a speech by Reiji Konishi, Representative Director and President of I-PEX Inc., followed by congratulatory and encouraging speeches from guests Mr. Yoshikawa (Deputy Director of the Environment Department of Fukuoka Prefecture) and Mr. Kido (Senior Specialist at the Center for Emergence Strategy at the Japan Research Institute, Ltd.).

The opening ceremony included a ribbon-cutting ceremony and a tour of the battery storage system products and factory, as well as an opportunity for stakeholders to interact with each other toward renewable energy and the circulation of local resources.
