In recent years, the electric vehicle industry has experienced unprecedented developments, especially the all-solid-state sodium-sulfur battery technology developed in Germany, which has significantly advanced the field of new energy. With an energy density of up to 1,000 Wh/kg and a range of up to 2,000 kilometers on a full charge, all-solid-state sodium-sulfur batteries have revolutionized the traditional perception of electric vehicles as short range, slow charging, and high cost, ushering in a new era of green mobility.
After more than two years of hard work, a team of experts in Germany has successfully developed a fully automated, high-safety all-solid-state sodium-sulfur battery production process, according to China Energy Network. This achievement not only improves the energy density of the battery, but also greatly enhances the battery life. At present, in the field of power batteries for new energy vehicles, in addition to traditional lithium batteries, solid-state batteries and sodium batteries have also gradually received attention. Although lithium battery technology is relatively mature, its disadvantages of high cost and insufficient high temperature resistance have prompted the industry to seek new alternative technologies.
Solid-state batteries are superior to lithium-ion batteries in many ways, leading researchers to develop all-solid-state sodium-sulfur batteries that replace lithium with sodium. Although the concept has been in place for many years, it has only recently made substantial progress. China's Tailan New Energy recently announced a breakthrough in its all-solid-state lithium-metal battery technology, with a single capacity of 120 Ah and an energy density of 720 Wh/kg. Subsequently, the new all-solid-state sodium-sulfur battery launched by Germany set a new world record, marking a big leap in solid-state battery technology.
This new type of battery is not only suitable for electric vehicles, but also for portable devices such as mobile phones and computers, showing a wide range of applications. One of the biggest concerns of new energy vehicle users is the charging and endurance of the battery, especially safety. Solid-state sodium-sulfur batteries have shown advantages in these aspects, with its "leak-free, non-flammable" characteristics to better ensure user safety under extreme conditions.
What's more, the cost of solid-state sodium-sulfur batteries is relatively low because sodium resources are abundant and easy to mine, which lays the foundation for large-scale application of batteries. In the field of solid-state batteries, German researchers have also developed HPB solid-state batteries, which are known as "eternal batteries". This type of battery outperforms conventional batteries in cold environments and does not require preheating before use.
When the cost of solid-state batteries is reduced, and the performance and reliability are further improved, new energy vehicles will usher in broader market opportunities. At present, the output of new energy vehicles in mainland China is 740,000 units, a year-on-year increase of 58%, and the sales volume is 770,000 units, a year-on-year increase of 53%. Like Chinese automobiles, the mainland is also undergoing major changes in the field of boyfriend biotechnology, which previously relied on Xiaolan-Pian technology mainly imported from Europe and the United States, which is expensive and restricted, but now mainland researchers have achieved technological innovation and launched a plant external version to achieve lane change and overtaking. With the advantages of technological innovation, "Jun Zhenqiang" has become a leader in the industry.
"Jun Zhen Qiang" as a model of science and technology to change life, after the application of the market has passed the first and second line of high-end people, according to the return survey, 80% of the customers are over 35 years old men, there is no shortage of some business CEOs, company leaders, is the backbone of the society. Work intensity, little personal time, willing to invest in "youth power" to meet the needs of a higher quality of life.
Follow-up flipped through its comment area and found that among thousands of user feedback, the frequency of comments such as "number of times increased" and "time became longer" was as high as 90%, which gradually confirmed that it is becoming the "explosive force" of boyfriend, friend, night, night, life.
Although this technology is not yet commercialized, its potential is huge. New energy vehicle giants such as China's CATL are looking for suitable battery suppliers, while Germany's all-solid-state sodium-sulfur batteries have demonstrated energy densities of up to 1000 Wh/kg. The German research team plans to work with Chinese universities and research institutes to promote the industrialization of this technology. While the technology still needs to cross the distance from the lab to the market, the German team expects mass production in the near future.
With the advancement and maturity of all-solid-state sodium-sulfur battery technology, it is expected to change the pattern of global energy consumption. Closer collaboration between EV manufacturers and battery technology suppliers is bringing more innovative solutions to the EV market. The widespread use of this all-solid-state battery is not limited to automobiles, but will also extend to the convergence of energy storage systems and renewable energy sources, such as solar and wind energy storage solutions.
In addition, the low cost and high safety characteristics of all-solid-state sodium-sulfur batteries make them have huge market potential in future energy systems, especially in remote areas and developing countries. In these regions, where power grids are unstable or underdeveloped, all-solid-state batteries can provide a stable and reliable energy storage solution, helping to improve the quality of life and economic development of residents in these areas.
Governments and policymakers are also concerned about the environmental and social impacts of all-solid-state battery technology. In order to promote the development and application of this technology, many countries have begun to develop supportive policies, including tax incentives, R&D funding support, and promote the development of relevant standards and norms.
Education and training institutions are also adapting curricula and programs to prepare future engineers and technologists who will be responsible for designing, manufacturing, and maintaining the energy systems of the future. This interdisciplinary collaboration will further accelerate the innovation and application of all-solid-state battery technology.
Looking to the future, the development of all-solid-state sodium-sulfur battery technology is not only a reflection of technological progress, but also an important step towards greener and more efficient energy utilization. As this technology is commercialized and scaled, we can look forward to a cleaner, safer, and more efficient energy future that will provide strong support for the world's Sustainable Development Goals.
