Since the 1980s, the Japanese government has provided long-term and stable support for the research and development of lithium-ion batteries and has formulated a roadmap and action plan for power battery research and development. Focus on researching and developing lithium-ion power battery cells, modules, standards, evaluations, and key raw materials. Japan has made significant breakthroughs in lithium battery technology and achieved commercialization of lithium batteries.
In order to cope with the rapid expansion of the global power battery market and reverse the relatively unfavorable situation of the current power battery market, Japan has once again put the development of power batteries on its agenda. By clarifying the development path and goals of the battery industry, we support the rapid development of battery technology.
The Japanese government's strategic plan for the battery industry
With the development of the pure electric vehicle market, the scale of the automotive battery market is also rapidly growing. Japan dominated the battery industry market in the early stages with its technological advantages, but as Chinese and Korean battery companies continue to seize market share, Japan has fallen behind.
In the battery supply chain, Japan's battery components are also losing competitiveness, and the risk of external dependence on raw materials and battery manufacturing is also increasing. In terms of battery material competitiveness, Japanese materials have advantages in terms of quality and market share. However, China has a cost advantage and material quality is also catching up.
In terms of raw material supply, the reserve and production of raw materials in the global battery supply chain are concentrated in Australia, Congo, and other places. The middle reaches of refining production are concentrated in China, and Japan's graphite materials rely on China's imports.
In terms of battery form, liquid lithium batteries are still the current mainstream, while Japan has always been in a leading position at the technology level of the highly anticipated new generation of all-solid-state lithium batteries. In order to achieve the goal of carbon neutrality by 2050 and improve the competitiveness of Japan's battery industry, Japan has released the "growth strategy" and planned the development goals of Japan's battery industry.
Ideas and Measures for the Development of Japan's Battery Industry
So far, the Japanese battery industry has mainly invested in the development of all-solid-state battery technology, while the competitiveness of liquid lithium battery technology has been completely surpassed by Chinese and Korean enterprises. Before the application of all-solid-state lithium batteries, liquid lithium battery companies faced the risk of being phased out. Therefore, the industrial strategy has formulated specific development directions and ideas for the future Japanese battery industry.
In terms of global competitiveness, Japan has also proposed the development direction of "enhancing global industrial competitiveness". On the basis of existing battery technology, Japan will maintain and strengthen its competitive level in the global market and carry out overseas strategic expansion.
From the perspective of standardization and international influence, the global production capacity of Japanese battery manufacturers will increase from the current 60-70 GWh/year to 600 GWh/year by 2030, and the global market share will increase to 20%. In order to achieve the above development direction and goals, Japan's industrial strategy has formulated seven specific actions to build and improve the ecological environment of Japan's local battery industry.
1. A package of policies to expand domestic battery material production facilities.
2. Establish a global battery industry alliance and global standards
3. Ensure the safety of upstream industries in the battery industry.
4. Develop next-generation battery technology.
5. Expand the domestic market in Japan
6. Strengthen human resource protection.
7. Improve the environment for battery manufacturing and utilization in Japan.
Japan actively deploys battery technology research and development plans
The lithium battery industry in Japan developed earlier and is relatively mature. At present, there are leading enterprises in various industry chains within the industry. The Japanese government has provided long-term and stable support for the research and development of lithium-ion battery technology, especially in recent years, increasing investment in solid-state battery research and development, making Japan account for 68% of international patents related to all-solid-state battery technology, ranking first in the world.
Currently, four of the top five companies in the world with solid-state battery patents are Japanese companies. The energy density of all-solid-state batteries is close to twice that of traditional lithium-ion batteries, and they have excellent charging and discharging performance, which will further shorten the charging time. Due to the reduction in the use of expensive raw materials, the cost of batteries can be kept low.
At present, progress is being made in the practical application of small batteries in electronic products, but large-scale automotive batteries are still in the stage of large-scale production technology development. To develop high-performance electric vehicles using all-solid-state lithium-ion batteries. Its goal is to develop first and next-generation batteries.
The goal of the first generation battery is to develop and improve the battery performance and continuous process of existing materials, and ultimately verify the continuous process of 450Wh/L batteries. The goal of the next generation of batteries is to collaborate with collaborative research institutions to create high-energy-density batteries by increasing the capacity of materials.
Summary:
Faced with the rapid development of Chinese batteries, the installed capacity and market share of Japanese companies are declining. Japanese battery and automotive companies are intensifying their layout of battery production capacity, especially increasing investment in the research and industrialization of solid-state batteries.
The Japanese government actively supports the research and development of battery technology, paying special attention to the deployment of future battery technology, with a focus on developing next-generation battery technologies such as all-solid-state batteries. Through the commercialization of new battery technology, we will enhance our global competitiveness in the battery field in the future.
Thanks to long-term investment from the government and enterprises in the field of all-solid-state battery technology, Japan has achieved significant advantages globally. With the rapid development of battery technology, leading technologies will help form industry advantages.
