Because nearly two-thirds of Japan's ground is Cenozoic extrusive rocks and new igneous rocks, the geological tectonic movement is intense and there are many faults. Therefore, Japan has a relatively complete variety of mineral resources, but its reserves are very small, so it is called "the country of metal resource specimens", which means that there are many types of mineral resources, but in fact the reserves are very small. As for lithium resources, talk is better than nothing. Therefore, it can be said that the shortage of lithium resources is the main reason why Japan embarked on the route of hydrogen energy batteries.
At present, there are two kinds of lithium mines that can be developed and utilized in the world, namely salt lake brine mine and pegmatite mine, which are abundant in total and concentrated in distribution, mainly in South America, Australia and China.
Because China's lithium resource reserves account for 20% of the world's total, and it has mastered the lithium resource supply chain, China has become the world's largest lithium battery market, with lithium resource consumption accounting for more than 40% of the world's total. As a result, power battery suppliers headed by Contemporary Ampere Technology Co., Ltd. and BYD have emerged in China, and they are all world-class top suppliers.
The main reason why Japan "went astray" and focused on developing hydrogen energy batteries is that Japan is surrounded by the sea, and the most important thing is water. Hydrogen used in hydrogen energy batteries is taken from water. Its basic principle is the reverse reaction of electrolytic water. Hydrogen and oxygen are supplied to the anode and cathode respectively, and the anode diffuses outward to react, and then reaches the cathode through external load to form energy, which is stored.
In short, Japan lacks lithium deposits and has no supply chain to control lithium resources, so they can't develop ternary batteries and can only go dark on the route of hydrogen batteries. So it is normal to miss the future of the lithium battery industry. After all, it is human nature to foster strengths and avoid weaknesses.
