Today, scientists have unveiled the long-sought-after mechanism of corrosion on anodes. Corrosion is a major issue for many industries, resulting in billions of dollars of economic losses every year. It is especially problematic for the energy storage industry, as anode corrosion can lead to a decrease in the performance of lithium-ion batteries.

The study, conducted by an international team of researchers, reveals that the corrosion of anodes is a result of the formation of microscopic pits on the surface of the material due to the dissolution of lithium ions. This process is accelerated by the presence of impurities, such as water and oxygen, in the electrolyte. The researchers were able to pinpoint the exact mechanism of corrosion, showing that the pits are formed due to the accumulation of ions on the surface of the anodes.

The team’s findings are an important step forward in understanding the corrosion process and could help to improve the performance and durability of lithium-ion batteries.
