For decades, lithium-ion batteries have been the preferred choice for mobile phones, electric vehicles, and other consumer electronics. But with the increasing demand for energy storage, lithium-metal batteries are becoming a more promising alternative: and Sweden has indeed the solution, with the Galvanization Technique
Researchers at Chalmers University of Technology in Gothenburg, Sweden, have announced a breakthrough that could enhance the durability of lithium-metal batteries. The team has studied the various reactions and processes occurring within the battery during charging and discharging to better understand what can be optimized.
The Galvanization Technique
The researchers propose a special galvanization technique as a solution. This approach involves creating metal electrodes within the battery cell, which they claim prevents the lithium metal from interacting with the environment and forming the harmful dendritic surface layer.
“Thus, we achieve a more predictable and stable electrode,” says Josef Rizell, a PhD student at the Department of Physics at Chalmers.
The research team at Chalmers is part of a broader, government-funded initiative called Compel. This program aims to advance research and education in electrification and battery technology.
“This is where we lay the foundation for future innovations that contribute to sustainable societal development. Batteries are already a central part of this development, and their importance will only grow in the future,” says Aleksandar Matic, the director of Compel.
