The Japanese battery industry
Japan is one of the major battery producing industries in the world and is also home to Battery Japan, the world’s biggest annual expo for rechargeable batteries. The exhibition is held twice per year at locations in either Osaka or Tokyo. For its 2021 event, Battery Japan is expecting high-profile visitors, such as the Japanese automobile manufacturers Mitsubishi, Nissan, and Toyota, as well as major electronics companies like Panasonic, Hitachi, and Toshiba. Panasonic, namely its subsidiary Sanyo, is a leading producer of lithium ion batteries and among the largest battery producers in the global market. Other Japanese battery manufacturers include companies like Kyocera, Sharp, and Sumitomo.
Current Developments in the Industry
For 2020, it was forecasted that over half of the lithium-ion batteries produced globally will be used in the automotive industry, primarily for electric vehicle production. Besides vehicle manufacturing, those battery types are commonly utilized as a power source for a variety of electronic consumer goods and power tools. Lithium-ion batteries are known for their sturdiness in different climate conditions like refrigerated systems.
