“Articles introducing four articles” about “materials for lithium batteries that Japan has absolute strengths” was posted.
First material:
“Lithium hexafluoride phosphate”.
So far, Japan has been monopolized, and only three companies have accounted for 75% of the world market share.
Lithium hexafluoride is a major raw material for lithium-ion batteries and is expensive.
China is focusing on domestic production.
However, the quality has not yet reached the level of Japan.
Second material:
“Aluminum laminated film”.
It is also reported that two Japanese companies occupy most of the world market.
Therefore, there is no choice but to import from Japan.
Replacement is effective even if it is made in Korea, but the quality is not as high as that made in Japan.
Chinese companies are still under research.
Third material:
It is a “battery protection IC”.
Fourth material:
Introduced “tab film”.
Regarding these, “It is a field where Japanese manufacturers have a great presence.”
Improvement of technology in China and South Korea:
The article conveys the strength of the materials used in Japanese lithium batteries.
It is certain that the technological capabilities of China and South Korea are improving.
