In the rapid development of the automotive industry, new energy technology has always been an important force to promote the industry. On the evening of April 8, at a press conference held in Shanghai, Zhiji Automobile, a subsidiary of SAIC, officially launched the Zhiji L6 smart car, which is not only another masterpiece of SAIC, but also the world's first model equipped with mass-produced "ultra-fast charging solid-state battery". This major breakthrough not only marks Zhiji Auto's leading position in the field of new energy, but also indicates that the entire automotive industry is about to usher in a revolutionary change.
At the press conference, Liu Tao, co-CEO of Zhiji Auto, introduced in detail the core technical highlights of the Zhiji L6 - the "Grey Lizard Digital Chassis" and the world's first mass-produced "ultra-fast charging solid-state battery". This innovative product, called "Light-Year Solid-State Battery", although only the first generation of solid-state batteries, has already significantly outperformed traditional batteries, achieving a power increase of more than 30% at the same weight. This is not only a major leap for liquid batteries, but also a huge boost to the technological progress of the entire industry.
The ultra-fast charging solid-state battery of the Zhiji L6 has a massive capacity of 133 kWh and is capable of achieving a CLTC range of more than 1,000 km. What's even more impressive is that thanks to the quasi-900V high-voltage platform, the Zhiji L6 can achieve a peak charging power of 400kW, which means that the driver and passengers can supplement the range of 400 km in just 10 minutes. Such charging efficiency is undoubtedly a major breakthrough in existing charging technology.
Zhiji Auto's achievements in the field of solid-state batteries are inseparable from the technical support of its partner Qingtao Energy. As an important enterprise in the research and development of solid-state battery technology in China, Qingtao Energy has received multiple rounds of financing in recent years, with a valuation of nearly 20 billion yuan, and its strength should not be underestimated. The cooperation between Zhiji Automobile and Qingtao Energy is not only reflected in the capital investment, but also in the in-depth integration of the two parties in technology research and development.
The technology of "high ionic conductivity, high-temperature resistant solid-state electrolyte" and "dry solid-state electrolyte layer integrated molding" adopted by Qingtao Energy greatly reduces the internal resistance of the battery and makes the battery have the ability to charge ultra-fast. At the same time, in order to enhance the lithium-ion conductivity of the solid-state electrolyte, Qingtao Energy added 10% sapizing solution to the electrolyte, an innovative measure that further improved the performance and safety of the battery.
Although Zhiji Auto's solid-state battery technology has received a lot of attention in the industry, it has also caused some controversy. Some industry insiders questioned that the battery is still "semi-solid", in this regard, Zhiji Auto said that there is no clear standard to define semi-solid and quasi-solid-state batteries, but products using solid-state electrolytes should be recognized as solid-state batteries. Zhiji Auto emphasized that they are committed to driving the industry forward through technological innovation, not playing with words.
The first-generation solid-state battery jointly developed by SAIC and Qingtao Energy has begun to be scheduled. The development of this technology not only brings the possibility of upgrading the existing lithium-ion battery system, but also brings new business opportunities for enterprises in the industrial chain.
The release of the world's first mass-produced ultra-fast charging solid-state battery model by Zhiji Automobile is not only an important breakthrough for SAIC in the field of new energy, but also a milestone in the development of the entire automotive industry. With the continuous progress of new energy technology, we have reason to believe that the future automotive industry will be greener, more efficient and more intelligent. For consumers, such technological advancements mean a more convenient, safe and comfortable travel experience, and for the industry, it is an opportunity for technological innovation and industrial upgrading. This innovative attempt of Zhiji Auto has undoubtedly injected new vitality into the development of the entire industry.
