Electronic components and electrodes for transforming, storing and shielding devices have ablated femtosecond pulsed laser machined with developed nano structures for substantially increasing surface areas. Storage is multiplied in capacitors and supercapacitors, and small sizes have increased capacity. Supercapacitor heating upon charging and discharging is reduced by femtosecond pulsed laser ablation of inner and outer surfaces of cases. Battery storage capacity and charging time, fuel cell size and capacity, hydrogen generation and storage and seconds are improved by femtosecond pulsed laser machining ablation of electrode surfaces followed by chemical vapor deposition of carbon nano structures.
