Abstract
Solid composite electrodes with electrode active layers that include an electrode active material, an optional electron conductive material, an optional binder and other optional additives for batteries which are not fuel cells are provided. The solid composite electrodes are formed by the deposition of an electrode composition (slurry) onto a current collector in one or many layers. The electrode structure may be characterized by a porosity of the electrode composition layer that decreases in a direction from the back side of the layer (close to the current collector) towards the outer side of the layer. The electrode structures can be used in for example chemical sources of electric energy such as primary (non-rechargeable) as well as secondary (rechargeable) batteries.
