On September 16, a 롤 스포츠토토 team led by Professor Lim Hee-dae from the Department of Chemical Engineering at Hanyang University, in collaboration with Professor Lim Hyung-gyu from the Department of Chemical Engineering and Bioengineering at Kangwon National University, announced that they have proposed an innovative solution to address the problem of uneven metal deposition in anode-free metal batteries. This breakthrough is expected to simultaneously improve performance, lifespan, and safety of the batteries.

Traditional 롤 스포츠토토 batteries have faced the limitation of needle-shaped dendrite growth caused by uneven 롤 스포츠토토 deposition during charge and discharge processes. These dendrites have been pointed out as a critical issue, leading to short circuits and potential explosions, while also hindering high-rate operation and long lifespan. Although countermeasures such as introducing complex additives or coating electrodes with thick protective layers have been studied, commercialization has been difficult due to high processing costs and reproducibility issues.

To tackle these challenges, the research team adopted a method that aligns the facets(orientation of crystal) of the current collector in a single direction. By simply heat-treating the commercially available zinc foil to align it with the (002) plane and reduce bumpiness of the surface and defects, the team achieved effective results. The team explained, “It works like replacing a gravel road with smooth pavement, allowing metal to grow laterally as if sliding to the side.”

The 롤 스포츠토토 was experimentally verified in magnesium secondary batteries, which are gaining attention as cost-effective next-generation batteries. Magnesium metal batteries hold advantages such as high volumetric capacity, abundant resources, and safety; however, commercialization has been limited due to uneven metal deposition. This study overcame the long-standing limitation and has elevated magnesium batteries as a promising next-generation commercial candidate to replace lithium-ion batteries.

Professor Lim stated, “We will continue follow-up studies to optimize this technology and enhance its scalability for mass production to get to commercialization of anode-free metal batteries. This method presents a breakthrough solution that meets the industry's requirements for simplicity, reproducibility, and scalability, representing a crucial turning point toward previously hindered commercialization.”

This research was supported by the National Research Foundation of Korea and was published online in September 2025 in Advanced Energy Materials (IF=26.0, JCR top 2.5%), an internationally renowned journal in the field of energy. The paper, titled “Facet-Guided in-Plane Metal Plating via Accelerated Surface Diffusion in Mg Metal Batteries,” lists Hanyang University researcher Ryu Hee-seung as the first author, and Professors Lim Hee-dae(Hanyang University) and Lim Hyung-gyu(Kangwon National University) as corresponding authors.
