On December 18, Hanyang University announced that a research team led by Professors Lim Hee-dae and Ko Min-jae of the Department of Chemical Engineering developed an innovative multidimensional current collector that can dramatically improve the lifespan and safety of lithium metal 토토사이트 바코드. This technology is expected to be a critical turning point in solving key issues hindering the commercialization of lithium metal 토토사이트 바코드.

With the accelerated adoption of electric vehicles (EVs) and the growth of the energy storage system (ESS) market, the demand for high-performance batteries that surpass conventional lithium-ion batteries is surging. Lithium metal batteries have an energy density ten times greater than lithium-ion batteries, and it’s gaining attention as next-generation energy storage devices thanks to their lightness and high capacity in applications such as EVs, drones, and aerospace. However, the key component of lithium metal batteries, the lithium anode, has a problem of forming dendrites during charging. The dendrites grow asymmetrically on the surface of the anode, not only degrading battery performance but also posing a severe threat to battery safety by causing internal short circuits and fires. This issue has been a significant barrier to the commercialization of lithium metal batteries.

To address these challenges, Professors Lim Hee-dae and Ko Min-jae’s research team jointly developed a novel multidimensional current collector technology suitable for the lithium metal anode. Conventional multidimensional collectors are limited in that they do not fully utilize the internal structure and fail to suppress dendrite formation as Lithium primarily deposits at the top. To overcome these limitations, the research team proposed a new method of depositing lithiophilic magnesium at the bottom of the current collector in a nanoscale in the form of a concentration gradient. The team successfully fundamentally suppressed dendrite growth by guiding lithium deposition from the bottom.

The newly developed current collector demonstrated over three times the lifespan stability compared to existing designs, significantly enhancing both the safety and performance of lithium metal 토토사이트 바코드. Furthermore, this technology allows for precise control over the collector's thickness and porosity, demonstrating its potential as a critical technical foundation for designing high-performance 토토사이트 바코드 with maximized energy density. This breakthrough is regarded as a pivotal advancement, which opens possibilities for applications in large-scale energy storage systems such as EVs, as well as next-generation electronic devices.

"This research holds significance in that it proposed a technology that simultaneously solves the issues of lifespan deterioration and safety, which have long been regarded as major issues of lithium metal batteries," said Professor Lim Hee-dae who led the research. "We plan to further refine this technology to accelerate the commercialization of lithium metal batteries." He further emphasized, "The current collector technology has the potential to be applied to various electrode materials, so it will provide a new paradigm across battery technology."

This research, titled "Electrochemically tailored host design with gradient seeds for dendrite-free Li metal batteries", supported by the Ministry of Science and ICT and the Young Researcher Support Project of the National Research Foundation of Korea, is scheduled to be published in the January 2025 issue of ACS Nano, an internationally renowned journal in the field of materials science. The research team revelated that it plans to continue follow-up studies to optimize the current collector structure and to increase the odds of mass production. This technology is expected to serve as a critical foundation not only for the commercialization of lithium metal batteries but also for the advancement of next-generation energy technologies.
