In the world of advanced energy storage, the performance and reliability of lithium-ion batteries depend heavily on the materials used at the microscopic level. Among these, the battery foil—usually aluminum for cathodes and copper for anodes—plays a critical role as the current collector. One of the greatest challenges in battery design is ensuring strong adhesion between the active material layer (electrochemically active compounds like lithium cobalt oxide or graphite) and the foil substrate. Weak adhesion can lead to delamination, reduced conductivity, increased internal resistance, and ultimately premature battery failure. This is where coating technologies have emerged as a transformative solution.
