Abstract

The invention encompasses batteries, battery electrodes and methods of forming batteries and battery electrodes. In one aspect, the invention includes a method of forming a battery electrode comprising: a) forming an electrode material mixture, the electrode material mixture comprising electrode active material, a conductive medium, and EPM; and b) curing the electrode material mixture to form an electrode having a thickness of less than 24 mils. In another aspect, the invention includes a battery comprising: a) a first electrode comprising: i) a thickness of less than 24 mils; ii) electrode active material; iii) a conductive medium; and iv) a binder comprising EPM; b) a second electrode; and c) an electrolyte between the first and second electrodes. In yet another aspect, the invention encompasses a battery electrode comprising EPM and a thickness of greater than 0 and less than 24 mils.
