Description
Wu and co-authors use shaped laser pulses to drill dense hole arrays through thick battery electrodes, in this 2025 paper. Thick electrodes store more energy, but their winding inner paths slow ions down. Holes can straighten those paths, yet older drilling routes waste material or space.
Their ultraviolet femtosecond laser cut holes six micrometers wide through electrodes two hundred eighty micrometers thick, losing under one percent of the material. The straighter paths cut the winding measure by about a fifth. Batteries built this way gained energy density at several charge rates, roughly doubled in power, and lasted twice as many cycles. The authors pitch the method for next-generation cells.
