The field of lithium battery production used to be Japan's strong point, but now the rise of Chinese and Korean companies has attracted the world's attention. With the advantage of the policy, China's local lithium battery manufacturers usher in the development opportunities, the rapid expansion of domestic lithium battery industry is the right time. Japanese companies have accelerated investment in the lithium industry in recent years to build a global supply network of lithium battery raw materials. The next interpretation of the Japanese lithium battery VS China lithium battery.
Japan lithium battery vs China lithium battery
The gap of core technology
All the core technologies of our domestic lithium battery manufacturing are not really innovative. As lithium battery is a very high core technology-intensive industry, every link from materials to equipment manufacturing needs core technology to support. In order to catch up with the lithium battery industry in Japan and South Korea, domestic enterprises had from soft packaging aluminum plastic film, diaphragm, electrolyte up to cathode materials are imported from Japan and South Korea as well as other countries, more than 30% of the entire domestic lithium battery materials from imports. For this reason, the manufacturing cost of domestic lithium battery cells is very high. In the past two or three years, the localization rate of diaphragm, electrolyte and cathode materials has increased rapidly and has now reached over 90%. However, due to the real core invention of these products is still very little, as well as the product has not gone through a long period of extensive experimental verification, it was put into commercial operation. This shows that the lithium battery material has an inherent deficiency compared with Japan and Korea.
The gap in manufacturing equipment
Equipment is one of the most critical parts to ensure product quality. It can be said that the prototype of the equipment manufactured by Chinese battery cell enterprises comes from Japan and Korea. Due to the use of imitation, it is inevitable that in some key core equipment can not do the requirements of Japanese and Korean equipment technology, although the shape is similar, but there is still a large gap between the substance. In particular, Japanese and Korean companies are worried about selling equipment to mainland China is imitated, set up a lot of obstacles in some key equipment, to crack is not an easy task. Therefore, due to the gap in equipment, there is a certain gap in the process of domestic lithium battery manufacturing.
●Gap in enterprise management
Although the gap between Japanese and Korean enterprises is narrowing, it is still a long way to go to reach the management requirements of Japanese and Korean enterprises. Especially in the case of domestic enterprises under increased competitive pressure, the loopholes in management will be constantly exposed, thus affecting the performance and quality of products.
Lithium battery domestic market, Chinese companies need to seize the market opportunity
In recent years, with the promotion of China's new energy vehicles, China has become the world's largest lithium battery production area and consumer market, in recent years, many foreign lithium enterprises have entered China, involving areas such as upstream cathode and anode materials, diaphragm, electrolyte, midstream core, downstream electric vehicles and other applications. With the increasing expansion of Chinese enterprises in the global market share, foreign related lithium battery manufacturers are accelerating their layout in China's market to seize the power source for the development of domestic new energy vehicles.
1, to market advantage, mass production of lithium battery products, reduce costs and improve mass production quality engineering capabilities.
2, invest in research and development to improve the energy density of lithium batteries, and new batteries, materials level of research and development capabilities.
3、Strengthen the ability of lithium battery intelligent manufacturing equipment research and development and advanced production technology.
4, accelerate the development of lithium battery system applications, system integration, from quantity to quality of the process, to improve the added value of products and services.
China has surpassed Japan in the number of papers published, second only to the United States, ranking second in the world, which shows that China is already a global leader in many research areas. Japan's focus is also changing - originally China was just a market for products and solutions for customers, but in the future China will become a center for research and development of cutting-edge products and lead technological change.
