  • Patent number: 9553314
    Abstract: An ultra-short pulse laser physically and/or chemically modifies a substrate surface. A laser ablation process is configured to form raised surface features on the substrate. The laser also functions as the energy source in a chemical vapor deposition (CVD) process. The laser delivers energy to the substrate with parameters such as pulse energy, size, duration, and spacing sufficient to simultaneously vaporize substrate material and cause the substrate material to react with a controlled environment that includes constituents of a desired coating composition. A battery electrode having a face with microneedle features coated with an active metal compound can be produced by the process. The active metal compound is a lithium-containing compound in a lithium-ion battery.
