The new generation of domestic "solid-state batteries" was successfully developed! Charging for 10 minutes and a range of 500 kilometers

It has been 10 years since the development of new energy vehicles. During these ten years, new energy vehicles have been comprehensively upgraded from the inside out. New energy vehicles were questioned in the early stages of their development. Many people felt that new energy vehicles had no future. , but judging from the current actual situation, new energy vehicles are indeed very popular. In 2022, my country's new energy vehicle sales will reach 6.68 million units, which is also the highest sales year since the development of new energy vehicles.

After entering 2023, new energy vehicle sales are still on an upward trend. From January to February 2023, sales reached 933,000 units, a year-on-year increase of 20.8%. More and more consumers are beginning to accept new energy vehicles. With the support of national policies, , new energy vehicles have developed rapidly, but the problem that is currently hindering the development of new energy vehicles is charging and battery life. Many consumers are worried about the battery life of pure electric vehicles, although the current battery life of pure electric vehicles exceeds 400 kilometers, which is enough to meet daily travel needs. , but it is really not suitable for long-distance driving, and the charging time is very slow. It takes about 8 hours to fully charge with normal charging and about 1 hour with fast charging. This is in sharp contrast to fuel vehicles.

If the battery life and charging speed of pure electric vehicles can be upgraded, I believe its sales will be far more than that. Major car companies have not stopped researching and developing power batteries, and many car companies have developed new solid-state power batteries. Domestic "solid-state battery" was successfully developed! Charging for 10 minutes has a range of 500 kilometers, dispelling users’ anxiety about battery life. What is the difference between solid-state batteries and common lithium-ion batteries? What new breakthroughs are there? Recently, Zhejiang's Huzhou battery production base, which has China's first high-energy-density solid-state battery production line, has 16 cells coming off the production line every minute. All the products produced here are semi-solid lithium batteries.

Less than a year after this power battery company went into production, its production line has reached full capacity. Even if it operates 24 hours a day, it cannot meet the order demand. It is understood that the higher the energy density of semi-solid battery cells, the longer the battery life. The longer the mileage, the traditional lithium-ion battery uses electrolyte to transmit energy. However, the organic solvent commonly used in this electrolyte is flammable. Once the battery pack is squeezed and severely impacted, it will easily cause spontaneous combustion. There is also the risk of explosion, so traditional lithium-ion batteries are relatively low in safety.

Solid-state batteries are different from traditional lithium-ion batteries. Solid-state batteries are not easy to explode, burn, and are resistant to high temperatures. Their application advantages are much higher than lithium-ion batteries. However, it is not easy to convert from liquid batteries to solid-state batteries, which is also the face of many car companies. The problem is solved, and the solid-state batteries produced at the Huzhou base were developed by a team led by Li Hong, a researcher at the Institute of Physics of the Chinese Academy of Sciences. China's solid-state batteries have experienced trial and error and constant iteration during more than 40 years of research and development, and are about to usher in the dawn of victory. .

At present, China's solid-state batteries have moved towards version 2.0, which is the second generation of solid-state batteries. The success of the new generation of solid-state batteries has brought China to the forefront of the world in the field of solid-state batteries. The energy density of the new generation of solid-state batteries has increased to 400 watt hours per kilogram. , can achieve the target of 500 kilometers of driving range after 10 minutes of charging. With the support of this technology, I believe that the development path of new energy vehicles will be smoother.
