AbstractLaser processes for cutting, annealing, structuring, and printing of battery materials have a great potential in order to minimize the fabrication costs and to increase the electrochemical performance and operational lifetime of lithium-ion cells. Hereby, a broad range of applications can be covered such as micro-batteries, mobile applications, electric vehicles, and stand-alone electric energy storage devices. Cost-efficient nanosecond (ns)-laser cutting of electrodes was one of the first laser technologies which were successfully transferred to industrial high-energy battery production. A defined thermal impact can be useful in electrode manufacturing which was demonstrated by laser annealing of thin-film electrodes for adjusting of battery active crystalline phases or by laser-based drying of composite thick-film electrodes for high-energy batteries. Ultrafast or ns-laser direct structuring or printing of electrode materials is a rather new technical approach in order to realize three-dimensional (3D) electrode architectures. Three-dimensional electrode configurations lead to a better electrochemical performance in comparison to conventional 2D one, due to an increased active surface area, reduced mechanical tensions during electrochemical cycling, and an overall reduced cell impedance. Furthermore, it was shown that for thick-film composite electrodes an increase of electrolyte wetting could be achieved by introducing 3D micro-/nano-structures. Laser structuring can turn electrodes into superwicking. This has a positive impact regarding an increased battery lifetime and a reliable battery production. Finally, laser processes can be up-scaled in order to transfer the 3D battery concept to high-energy and high-power lithium-ion cells.

Template Process

Uniform and aligned Nickel Oxide (NiO) nanotube bundles have been synthesized by a template process. Individual nanotubes are 60 μm long with a 200 nm outer diameter and wall thickness of 20–30 nm. The synthesis involved forming Ni(OH)2 nanotubes that were subsequently heated to 350°C in order to fully convert the product to NiO nanotubes. NiO nanotube powder was used in lithium-ion cells for assessment of lithium storage ability and electrochemical performance. Discharge capacity of the NiO nanotube electrode was in excess of 30% higher than that of the standard NiO nanocrystalline powder electrode after 20cycles. Impedance data suggests the NiO nanotube electrode provides more controlled and sustainable Li diffusion when compared to the NiO reference powder electrode system.
