In recent years, the progress of South Korean and Chinese battery manufacturers has been particularly remarkable in the lithium-ion battery market for consumer use. On the other hand, although the market of the lithium-ion battery for automobile use is also expanded, it is still in a developing stage. Consequently, it is important to analyze the architecture promptly and to employ in a future manufacturing strategy efficiently. In this research, the product and the process architecture of the lithium-ion battery for automobile use were clarified. Furthermore, consideration was added about the positioning strategy of the architecture of the lithium-ion battery for automobile use.
