Professor Jong-sung Yu's team developed a nitrogen-doped porous carbon material that boosts lithium–sulfur battery performance, achieving rapid charging (12 minutes) and long-term stability (82% capacity retention after 1,000 cycles). This breakthrough could accelerate battery commercialization.

    Even under rapid charging conditions with a full charge time of just 12 minutes, the battery achieved a high capacity of 705 mAh g⁻¹, which is a 1.6-fold improvement over conventional batteries. Furthermore, nitrogen doping on the carbon surface effectively suppressed lithium polysulfide migration, allowing the battery to retain 82% capacity even after 1,000 charge–discharge cycles, demonstrating excellent stability.

    Assuming that this is scalable for production… Which is a big if for many of these “breakthroughs”, then this could replace current Lithium Ion batteries in most devices with a noticeable bump in capacity. Everything else is pretty par for the course though with current technologies.

    The full charge time is meaningless without knowing what capacity they were working with. And a quick skim didn’t seem to have that in the article.
