Laser-induced structures in graphite anodes have been reported to improve various performance characteristics of lithium-ion batteries. Nevertheless, electrode structuring has been studied mostly with single-layer coin cells on a laboratory scale to date.
At present, lithium-ion batteries (LIBs) are the predominant solution for portable electronic devices and electric vehicles due to their high energy density and continually declining price, .
Due to the growth in these and other markets, the demand for lithium-ion batteries also continues to grow, motivating the development of lower cost, faster production methods. Lithium-ion batteries have a layered structure, comprised of several elements: a cathode battery foil, an anode battery foil, a separator material, and an electrolyte.
In particular, at high electrode thicknesses, the lithium-ion mobility is impeded by long diffusion pathways resulting in large lithium-ion concentration gradients and overpotentials during rapid charge and discharge .
The improvements can be mainly attributed to decreased lithium-ion concentration gradients in the electrolyte and a reduction of the accompanying overpotentials, . Thus, the improved performance of the structured cell can be assigned to a facilitated lithium-ion transport within the porous anode through the laser-induced migration paths.
