The main advantages of the SpaceX darlinks satellite's use of Hall-effect thrusters and krypton-propellant Hall-effect thrusters are that it uses an electron cloud instead of a grid to attract and accelerate ions, which prevents corrosion of the grid, access systems use non-toxic liquid salt-based propellants, they avoid the use of ionization chamber pressurized tanks and valves, they designed a chip with propellant holes that apply a strong electric field to accelerate the thrust of ions, which is called electrospray propulsion, just like inkjet printers work
