At present, it can require numerous hours to completely charge the battery of an electric vehicle, potentially even up to 10 hours. Despite the implementation of fast charging technology, it still takes a minimum of 30 minutes to fully charge an electric vehicle battery. Nevertheless, overcharging an electric vehicle battery can lead to battery deterioration or ignite a fire.
In order to address this issue, a team of researchers from Korea has achieved a breakthrough by creating a novel anode material that enables electric vehicle batteries to be fully charged within a mere 6 minutes.
Researchers utilized a sophisticated technique to synthesize ultra-thin manganese ferrite nanosheets, which were then employed to develop a novel material for lithium-ion battery anodes. By expanding the surface area of the anode, it became possible to enhance the mobility of a significant quantity of lithium ions, thereby increasing the ion storage capacity to approximately 1.5 times the theoretical threshold. Consequently, the charging speed of electric vehicle batteries has been accelerated, enabling rapid charging in a mere 6 minutes, thereby reducing the necessity to charge the vehicle overnight.
Specifically, the introduction of this new technology will not shorten the lifespan of electric vehicle batteries.
Professor Won Bae Kim, the leader of the research, commented that the new technology aligns with international endeavors for eco-friendly and effective transportation systems. This technology will contribute to the growing popularity of electric vehicles worldwide.
The outstanding results of this research by Korean scientists have been acknowledged and published in specialized journals, as reported by Scitechdaily.
