Researchers from the University of Adelaide and Imperial College London have developed a new silicon-anode lithium-ion battery cell designed to achieve ultra-fast charging without the rapid degradation and heat generation typically associated with current high-capacity batteries.
**Key Performance Metrics:**
* Reaches 85% charge in 6 minutes, and 91.4% charge in 10 minutes.
* Delivers an energy density of 240.4 watt-hours per kilogram (Wh/kg).
* Retains approximately 76% of its original capacity after 500 consecutive six-minute fast-charging cycles.
* Achieves an average coulombic efficiency of 99.94% (the ratio of charge output to charge input).
**The Technology:** Traditional fast charging generates excess heat that accelerates degradation and raises safety risks. Standard engineering solutions often involve reworking the electrolyte (the medium ions travel through), but this tends to compromise overall ionic conductivity.
To bypass this, the research team targeted the electrode surface rather than modifying the entire electrolyte system. They used sulfur vacancies as catalytic sites to attract specific anions to the battery interface during charging. This process promotes the formation of a compact, lithium fluoride-rich protective layer—the solid electrolyte interphase (SEI) – which contains built-in pathways for fast lithium-ion transport. By regulating the reactions only at the interface, the strategy enables rapid charging and long-term stability without sacrificing ionic conductivity or generating excess heat.

wasn’t there a post about BYD cars and charging from 0-90% in 5 minutes?

fast charging is nice and all but I want a battery I can slow charge for 10,000 cycles with almost zero degradation and charge from zero to 100% then drain it back down to zero with no degradation and then proceed to store it under a cabinet for a few years and decide to pop it back out and use it again with no problems.
fast charging is near the bottom of my list of wants for a battery.

If I had a nickel for every time I hear a new breakthrough in batterys that never materiazle I would have a few dollars.
