Electric vehicles have become the protagonists of future transportation, but their range and charging speed have always been the key bottlenecks restricting their large-scale promotion. However, the landscape is changing dramatically. Recently, the German R&D team successfully developed an all-solid-state sodium-sulfur battery, breaking people's inherent impression of electric vehicles. Not only does this new battery technology provide a range of more than 2,000 km, but it can also be charged extremely quickly, making it truly "zero compromise" for e-mobility. This major technological breakthrough will surely promote the entire new energy vehicle industry into a new stage of development.
Technological breakthrough in all-solid-state sodium-sulfur batteries
1.1 Ultra-high energy density, cruising range of more than 2000 km
After two years of painstaking research and development, the German scientific research team has finally successfully developed a new all-solid-state sodium-sulfur battery. The energy density of this battery is as high as 1000 Wh/kg, which is nearly 3 times higher than that of today's mainstream lithium-ion batteries. When fully charged, an electric vehicle using this battery can travel more than 2,000 kilometers, completely subverting the inherent impression that electric vehicles have a short range.
At the heart of this technological breakthrough lies in the application of all-solid-state structures. Compared with traditional lithium-ion batteries, all-solid-state batteries use a solid-state electrolyte instead of a liquid electrolyte, which can not only greatly improve energy density, but also greatly improve safety. The solid electrolyte does not leak or burn and remains stable even in extreme environments. This provides a more reliable power guarantee for electric vehicles, and also lays a solid technical foundation for the widespread popularization of electric mobility in the future.
1.2 Fast charging, 15 minutes can add 500 km of range
In addition to the ultra-high cruising range, another highlight of the all-solid-state sodium-sulfur battery is the extremely fast charging speed. Compared to the hours of charging time of a regular electric car, it only takes 15 minutes to use this battery to increase the range by 500 kilometers. This not only greatly improves the user's travel experience, but also brings new possibilities for the practical application scenarios of electric vehicles.
The secret to this fast charging lies in the all-solid-state construction. Solid-state electrolytes have a higher ionic conductivity than liquid electrolytes, which results in a much higher rate of ion transport within the battery. At the same time, the all-solid-state structure can effectively avoid the problems of volume expansion and electrode dissolution during the charging process, so as to ensure the stability of the charge-discharge cycle.
In general, the breakthrough progress of all-solid-state sodium-sulfur batteries in the two key indicators of cruising range and charging speed will surely promote the electric vehicle industry to achieve a qualitative leap and truly realize the green travel era of "zero compromise".
