Whereas electric vehicles typically require several hours for a full charge, an innovation led by Professor Won Bae Kim and his research team at POSTECH significantly narrows this time span to a mere six minutes. The team achieved this breakthrough by utilizing manganese ferrites nanosheets, generated through a distinct synthesis method, which enhances both battery capacity and charging rate.
Conventionally, electric vehicle batteries require approximately 10 hours to charge. Even the most advanced fast-charging technologies merely reduce this duration to a minimum of 30 minutes, assuming a vacant slot at a charging station is available. The ability to charge electric vehicles as quickly as fossil fuel vehicles could mitigate the scarcity of electric vehicle charging locations.
Professor Won Bae Kim of the Department of Chemical Engineering and the Graduate Institute of Ferrous & Energy Materials Technology at Pohang University of Science and Technology (POSTECH, President Moo Hwan Kim) steered a research initiative aimed at crafting a new anode material for lithium-ion batteries, the prevalent type utilized in electric vehicles.
The research has been acknowledged for its quality and was prominently published in the journal Advanced Functional Materials.
Joining Professor Kim in this endeavor were Ph.D. candidates Song Kyu Kang and Minho Kim. The team synthesized manganese ferrites (Mn3-xFexO4) nanosheets via an innovative self-hybridization process rooted in a simple galvanic replacement technique. Remarkably, this novel method amplifies storage capacity to roughly 1.5 times the theoretical maximum and enables electric vehicles to achieve a full charge in just six minutes.
In this study, researchers employed a unique synthesis method for manganese ferrites, a material known for its outstanding lithium-ion storage capacity and magnetic properties. The galvanic replacement reaction occurred in a manganese oxide and iron solution, resulting in a heterostructure compound comprising internal manganese oxide and external iron oxide layers.
The team then utilized a hydrothermal procedure to generate nanometer-thick manganese ferrites sheets with expanded surface areas. Through the control of highly spin-polarized electrons, the process considerably amplified the storage capacity, accommodating a significant quantity of lithium ions. This development enabled the research team to surpass the theoretical storage capacity limits of manganese ferrites anode material by over 50%.
By increasing the anode material’s surface area, the researchers facilitated the rapid movement of a high volume of lithium ions, thereby improving the battery’s charging speed. Experimental outcomes confirmed that a battery of equivalent capacity to those currently in electric vehicles could be fully charged and discharged in just six minutes. The study paves the way for innovations that could fundamentally enhance both battery charging times and storage capacity.
Professor Won Bae Kim, who led this groundbreaking research, stated, “By applying rational design in conjunction with surface alteration via electron spin, we have provided new insights into how to transcend the electrochemical constraints of traditional anode materials. This could significantly enhance battery longevity and decrease charging times for electric vehicles.”
The study was funded by the Mid-Career Researcher Program, the Advanced Research Center Program of the National Research Foundation of Korea, the Ministry of Science and ICT, and the Ministry of Trade, Industry and Energy Program dedicated to enhancing next-generation rechargeable lithium-ion batteries and developing new manufacturing technologies.

Mn3-xFexO4 as an anode material? Revolutionary. But I’m curious about its long-term durability and any potential trade-offs.
This could shake up the whole automotive market. Traditional car makers better catch up or they’re gonna get left in the dust.
Wow, just 6 mins to charge an EV? That’s game-changing. i always thought that long charging times were a deal-breaker for me but now i’m reconsidering.
Anyone got the stock ticker for POSTECH? Or maybe Prof. Kim’s team has a startup? This is where the money’s gonna be.
Sounds too good to be true. Would love to see how it performs in real-world conditions, not just lab tests.
im no scientist, but if this means I can charge my car as fast as I fill up my gas tank, then sign me up.
If this is for real, it’s not just a win for electric car owners, but a big win for the planet too. Fossil fuels, your time is up.
gotta say, i’m all about old school combustion engines, but this is mindblowing. If they pull this off, i might just swap to an electric.
Impressive! Prof. Kim and his team are on the verge of revolutionizing the entire electric vehicle industry. Finally, battery tech catching up.
This is exactly the push we need for more ppl to adopt electric vehicles. less time at the charging station means its way more convenient.
