Particles of active electrode material, such as a fibrillized mixture of carbon, and binder are deposited onto a surface of a current collector sheet. The current collector sheet and the particles are processed in a high-pressure nip, such as a calender. As a result of the high-pressure processing, a film of active electrode material is formed on and bonded to the surface of the current collector sheet. The process is then repeated to form a second film on the second surface of the current collector sheet. In an embodiment, the particles are applied to both surfaces of the current collector sheet at the same time, followed by a pass through a calender. The current collector sheet with the bonded films is shaped into electrodes suitable for use in various electrical devices, including double layer capacitors.
