Laser-Materials Processing for Energy Storage Applications

This chapter will review the use of laser-based material processing techniques, such as pulsed laser deposition (PLD), laser-induced forward transfer (LIFT), and material processing via 3D laser structuring (LS) and laser annealing (LA) techniques for energy
storage applications. PLD is a powerful tool for fabricating highquality layers of materials for cathodes, anodes, and solid electrolytes for thin film microbatteries. LIFT is a versatile technique for printing complex materials with highly porous structures for the fabrication of micropower sources, such as ultracapacitors and thick-film batteries. LS is a recently developed technique for modifying the active material by forming advanced 3D electrode architectures and increasing the overall active surface area. LA is a rapid technology for
adjusting the crystalline battery phase and for controlling the grain size on the micro- and nanoscale. This chapter will review recent work using these laser processing techniques for the fabrication of micropower sources and lessons learned from the characterization
of their electrochemical properties.
