"high power density, quick charge and longer lifetime... efficient laser-based drying of water-based electrode coating... diode laser projects high-intensity beam onto copper foil graphene coated which absorbs energy heats up and liquid evaporates... reduce energy 50% and space needed 60%...  high-power ultrashort pulse laser 1 mJ pulse energy introduces hole structure (channels) into electrode... multi-beam arrangement for parallel process control. Four scanners each with six beamlets, process in parallel"
