With the increasing attention given to electric vehicles due to their impact on the environment, the demand for high-quality LIBs–which are a source of power–has increased rapidly, and technological innovation to improve productivity has become a pressing need. The key to improving manufacturing efficiency is the development of camera technology that accurately captures the position of fast-moving objects. The successive repetition of errors led us to devise our own imaging technology that succeeded in ultrahigh speed shooting. This technological innovation has increased the daily production capacity of each production line by 18% and annual production by 130,000 units. OEZ is contributing to the protection of the environment and the realization of a sustainable society through further technological innovation along with our customers.
