Japan and Europe will cooperate in recycling batteries for electric vehicles (EVs). By 2025, a mechanism for sharing information on mining sites and suppliers of minerals used in batteries will be established. Through tracking information, rare metals such as lithium are prevented from leaving overseas, and reuse is promoted. This is to counter China, which has a high market share in battery materials. The Japanese government is developing an autonomous industrial data platform known as the “Uranos Ecosystem.” In addition to major Japanese automobile companies such as Toyota, Nissan, and Honda, more than 50 Japanese companies, including Prime Planet Energy & Solutions, an EV battery company funded by Toyota and Panasonic Holdings, and Denso will also participate. In Europe, there is already an official and private data platform “Catena-X” dominated by car manufacturers and the like. In addition to confidential information related to the core competitiveness of Japanese companies, such as suppliers and procurement volumes of materials and components, Ulanos and Catena-X will be shared by 2025.
