Japan is accelerating the research and development of solid-state batteries, trying to overtake in a corner? China does not agree!

Recently, China's four major departments jointly issued a document to increase research on key technologies of power batteries . This move is of special significance to China's new energy vehicle industry, which has achieved outstanding upgrades . It means that China will unite the entire industrial chain to ensure that China is at the core of new energy vehicles. Technical leadership.

1. The document on joint research and development to accelerate technological breakthroughs proposes that multiple industries collaborate to promote core technology research on vehicle-network interaction, increase the cycle life of power batteries to 3,000 times or more without significantly increasing costs, and overcome high-frequency two-way charging and discharging conditions. The battery safety prevention and control technology can be said to directly address the technical difficulties of current new energy vehicles.

The penetration rate of new energy vehicles in China has reached 30%, accounting for 60% of the global new energy vehicle market. However, with the popularity of new energy vehicles, the technical shortcomings of existing lithium-ion batteries have become increasingly prominent, such as charging speed, safety , battery life are all difficulties in accelerating the popularity of new energy vehicles.

If these technologies can be broken through, they will further consolidate China's leadership in the global new energy vehicle industry. More than 60% of the world's power batteries are produced in China. Six of the top ten power battery companies in the world are Chinese companies. Among the existing three In terms of lithium-ion batteries and lithium iron phosphate batteries , China has taken a leading position in the world.

Due to China's existing technical foundation in lithium-ion batteries and its complete industrial chain, joint research and development is indeed expected to accelerate the technological breakthrough of power batteries. After all, the breakthrough of battery technology involves many industries such as materials and chips . Joint research and development It helps to open up all links, lead from point to point, and achieve comprehensive breakthroughs.

2. Japanese automobile power battery technology

Japanese cars undoubtedly have strong strength in the global automobile market. Toyota has ranked first in the global automobile industry for many years. However, after the rise of new energy vehicles, Japanese cars failed to seize the opportunity, resulting in lagging behind China and the United States in the new energy vehicle market. and Europe, for which Japan is trying to accelerate the research and development of solid-state battery technology.

In order to achieve overtaking in corners, Japan is increasing its efforts to develop solid-state battery technology, hoping to rely on breakthroughs in battery technology. Toyota has earlier stated that solid-state batteries have made a major technological breakthrough and can achieve 1,200 kilometers of battery life with a 10-minute charge . However, this technology has not been released until 2027. Annual mass production.

In terms of solid-state battery technology patents, Japanese media have analyzed that the Japanese automobile industry has greater advantages and holds more patents, proving that they indeed have stronger strength in the research and development of solid-state battery technology.

If Japanese cars can indeed advance solid-state battery technology as scheduled, then Japanese cars are indeed expected to catch up with latecomers in the new energy vehicle market. This makes the Chinese automobile industry feel urgent, so it is necessary for various Chinese automobile industries to jointly develop advanced battery technology.

3. China’s automobile industry is expected to accelerate breakthroughs in battery technology

China's automobile industry actually has its own layout in solid-state battery technology. Power battery companies have stated that they have always invested in the research and development of solid-state battery technology. Earlier, Guangzhou Automobile Group and Tsinghua University announced major breakthroughs in solid-state battery technology. These all show that China is in Solid-state battery technology has always been attached great importance to.

The development of battery technology is not a sudden change, but a gradual evolution. The Chinese automobile industry is also advancing the technical route from semi-solid batteries to solid-state batteries based on existing battery technology. Some automobile companies have stated that semi-solid batteries have reached mass production. In the first stage, by first developing semi-solid-state batteries and testing related technologies in practice, it will be more feasible to finally realize solid-state batteries.

At the end of 2023, the State Intellectual Property Office pointed out that China has invested heavily in solid-state battery technology in recent years, and the number of solid-state battery patents applied by various companies has grown rapidly. In the past five years, the number of solid-state battery patent applications in China has increased by an average of 20.8% annually, with the growth rate ranking among Ranking first in the world, as of May 2023, China’s solid-state battery patent share has reached 36.7%.

China already has a solid foundation for battery technology and industrial chain. With the cooperation of all parties, it is believed that China's new energy vehicle industry can gain a leading edge in advanced battery technology and continue to maintain its leading position in the new energy vehicle industry. Japanese cars are trying to make corners. Overtaking will only result in being intercepted by China.
