Researchers from South Korea have developed a new generation of lithium-sulfur batteries. It should be able to be fully charged within twelve minutes.
Researchers from South Korea have developed a new technology that could make lithium-sulfur batteries (Li-S) suitable for everyday use. They managed to fully charge a battery in just twelve minutes – with apparently unprecedented efficiency and stability.
Compared to lithium-ion batteries, lithium-sulfur batteries have some advantages. They have a higher energy density and are based on sulfur, a cheap and readily available material. These properties make the battery particularly attractive for applications such as electric vehicles or stationary energy storage.
Lithium-sulfur batteries can withstand 1,000 charging cycles
Until now, slow charging times and loss of capacity due to chemical reactions inside the battery have been obstacles to commercialization. The team led by Professor Jong-sung Yu from DGIST (Daegu Gyeongbuk Institute of Science and Technology) therefore developed a new type of carbon material that is doped with nitrogen and is porous.
This material solves several problems. Thanks to a special structure, the chemical reaction between sulfur and lithium accelerates, allowing charging times of just twelve minutes. Even after 1,000 charging cycles, the battery retains 82 percent of its capacity. This shows that it remains stable in the long term.
In the test, the battery achieved a capacity of 705 milliamp hours per gram. This is around 1.6 times more than conventional batteries.
Commercialization could be imminent
What is special about the new approach is the structure of the carbon material, which is produced through thermal reduction with magnesium and an organic frame material (ZIF-8). This structure provides plenty of space for sulfur and improves contact between sulfur and the electrolyte.
Nitrogen on the surface also prevents the migration of lithium polysulfides, which would otherwise affect the battery’s performance. The fast charging capability and long-term stability make this battery a promising alternative for the energy transition.
Although further optimization is needed, this technology could accelerate the commercialization of lithium-sulfur batteries and reduce reliance on expensive materials such as cobalt and nickel.

As a Tech Industry expert, I am thrilled about the potential of the new lithium-sulfur battery that can be fully charged in just 12 minutes. This breakthrough has the potential to revolutionize the way we use and store energy in various applications, from electric vehicles to portable electronics.
The fast charging capability of the lithium-sulfur battery addresses one of the major limitations of current lithium-ion batteries, which can take hours to charge fully. This means that users can spend less time waiting for their devices to charge and more time using them.
Additionally, the use of sulfur in the battery’s cathode offers a more sustainable and cost-effective alternative to traditional lithium-ion batteries. Sulfur is abundant, low-cost, and environmentally friendly, making it an attractive option for mass production.
Overall, the development of a lithium-sulfur battery that can be fully charged in just 12 minutes is a significant advancement in battery technology. It has the potential to improve the efficiency and performance of various electronic devices while also reducing our reliance on fossil fuels. I am excited to see how this technology continues to evolve and make a positive impact on our daily lives.
