description Secondary batteries and methods of manufacture thereof are provided. A secondary battery can comprise an electrode layer comprising a population of spacer structures comprising a material other than the electrode active material, wherein (a) the spacer population occupies a total volume within the electrode layer within the range of about 0.1% to about 35% of the volume, VE, of the electrode layer, and (b) a member of the spacer population is located within each subvolume of the electrode layer comprising (i) at least 25% of the volume, VE, of the electrode layer, and (ii) bounded on all sides by (aa) the unit cell portion of the electrode current collector, (bb) the separator layer, (cc) the top surface of the electrode layer, (dd) the bottom surface of the electrode layer, (ee) the first end surface of the electrode layer, and (ff) the second end surface of the electrode layer.
