Pulsed Laser Deposition-based Thin Film Microbatteries.

Emerging applications for robust small format or distributed devices feature a need for power and rechargeable lithium-ion batteries could play a significant role. This review focuses on a high precision technique to controllably grow thin-film electrodes or full all-solid-state batteries, that is, pulsed laser deposition (PLD). The technique and solid-state batteries are introduced followed by a detailed showcase of the depth of PLD-based growth undertaken on cathodes, electrolytes, anodes and whole microbatteries. Emphasis is placed on the various characterization techniques available to study PLD grown components and devices, and how interfaces become both critical and arguably easier to probe in PLD grown films or devices. This work provides a perspective on the techniques, its opportunities for electrodes and devices, and how to probe the resulting growth and its evolution in batteries.
