METHOD OF MANUFACTURING SOLVENTLESS MULTILAYERED ELECTRODES

A method for manufacturing a solventless multilayered electrode may include mixing electrode particles with binders to form dry electrode mixtures, compressing the dry electrode mixtures to form electrode films, stacking the electrode films, and compressing the stacked electrode films. Suitable electrode films may include active material particles, conductive particles, electrochemically inactive ceramic particles, and/or the like. In some examples, compressing the stacked electrode films may include compressing the electrode films between pairs of rollers having patterns disposed on one or more exterior surfaces, thereby increasing surface roughness of the electrode films. A system for manufacturing solventless multilayered electrodes may comprise a first plurality of rollers configured to compress dry electrode mixes into electrode films, and a second plurality of rollers configured to compress a stack of electrode films into a single electrode stack.
