Electrodes are essential components of modern lithium-ion batteries, which are used to power mobile electronic devices, electric vehicles, and many other products. The battery’s surface structure and engineering are directly related to its performance, life expectancy, and safety.

The batteries are manufactured using advanced fabrication technologies, and their quality must be checked to help ensure they are being made correctly. In particular, the surface roughness of the battery’s electrodes must be strictly controlled. Inspecting lithium-ion battery electrodes can be challenging but using a laser confocal microscope enables manufacturers to overcome these challenges to help ensure the quality of their products.
