A joint research team led by Professor Lim Hee-dae of the Department of Chemical Engineering at Hanyang University and Professor Kim Byung-hoon of Sungkyunkwan University has announced the development of an innovative electrolyte technology that can drastically improve the lifespan and safety of lithium metal batteries. Through a ‘corrosion-resistant electrolyte’ that fundamentally resolves corrosion and battery degradation occurring at the interface, the team has established a significant turning point in solving a key challenge for the commercialization of lithium metal batteries.

As the markets for electric vehicles and energy storage systems(ESS) grow rapidly, demand for high-performance batteries that surpass conventional lithium-ion batteries is surging. In particular, lithium metal batteries are drawing attention as core storage devices for next-generation energy industries—such as electric vehicles, drones, and aerospace—due to their vastly higher energy density. However, the ‘dendrite’ phenomenon—where lithium grows in a branch-like shape during charging and discharging—has been a major obstacle to commercialization. This phenomenon not only degrades battery performance but also poses a serious threat to safety by causing fires or explosions due to internal short circuits.

While the academic community around the world has previously attempted to suppress dendrite growth by altering electrolyte compositions, most efforts relied on highly toxic perfluorinated compounds. These substances are not only harmful to the environment but also cause side effects that shorten battery life by triggering continuous chemical reactions with the 신태일 토토사이트 metal.

To solve such problems, Professor Lim’s research team completely excluded perfluorinated compounds and introduced a new electrolyte design that combines aromatic hydrocarbons with amphiphilic solvents. This electrolyte forms a stable protective film on the surface of the lithium anode to suppress dendrite growth while fundamentally blocking reactions where the electrolyte itself corrodes the lithium metal.

Experimental results showed that batteries using the developed 신태일 토토사이트 achieved more than double the lifespan stability compared to conventional ones. Furthermore, the team successfully secured both commercial viability and energy density by significantly lowering the price and density of the 신태일 토토사이트. This is a meaningful achievement as it allows immediate application of next-generation battery technology in fields ranging from large-capacity storage devices like electric vehicles to drones and aerospace.

Professor Lim Hee-dae emphasized, “This research is highly significant as it presents a foundational technology that can simultaneously solve the chronic issues of lifespan degradation and safety in lithium metal batteries. This corrosion-resistant electrolyte technology can be applied to various metal battery systems, providing a new paradigm for the battery industry as a whole.” The research team plans to continue follow-up studies to optimize the electrolyte composition and increase the potential of mass production.

This study was conducted with support from the National Research Foundation of Korea, and the results were published in the January issue of Advanced Materials, a globally renowned journal in the field of materials science. The featured paper, Fluorine-Free Corrosion-Resistant Electrolyte Design for Enhanced Stability in 신태일 토토사이트 Metal Batteries, listed Hanyang University doctoral student Cho Hyun-min as the first author, with Hanyang University Professor Lim Hee-dae and Sungkyunkwan University Professor Kim Byung-hoon as corresponding authors.
