Abstract
Electrodes of an electrical charge storage device are separated by forming on the surfaces of the electrodes arrays of substantially uniform electrically insulating microprotrusions made preferably of an organic epoxide polymer. The electrodes are thin, flat electrically conducting metal sheets coated on one or both flat surfaces with electrically conducting porous carbon or a porous metal oxide. The microprotrusions are applied to the coated electrodes through a stencil by screen printing and essentially retain their shape and dimensions after curing.
