Abstract
A porous product, typically a foam sheet, can be produced by peeling of a foam supply. By peeling the foam supply along its z axis, a product is produced having pores with a uniform pore aspect ratio in the longitudinal direction. Such a porous product, when containing an active filler, can be used as a battery electrode. The electrode can have enhanced electrical and mechanical properties.
