Abstract: A method of fibrillizing a fibrillizable binder component of an electrode film can include providing a negatively charged fibrillizable binder component, and applying an electric field upon the negatively charged binder component to fibrillize the negatively charged fibrillizable binder component. A system for fibrillizing a binder component of an electrode film can include a mixing container made of a material having an affinity to donate electron(s) to the binder component, and an actuator configured to apply a force upon the mixing container so as to contact the mixing container with the binder component and to move the mixing container and the binder component relative to each other within a speed and range of motion sufficient to create an electrostatic force on the binder component and fibrillize the binder component.

Abstract: An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode comprises a first lithium ion intercalating carbon component and a second lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, and the second lithium ion intercalating component can include graphite or soft carbon. A ratio of the hard carbon to the graphite or of the hard carbon to the soft carbon can be between 1:19 to 19:1. The anode may comprise a first lithium ion intercalating carbon component, a second lithium ion intercalating carbon component and a third lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, the second lithium ion intercalating carbon component can include soft carbon, and the third lithium ion intercalating carbon component can include graphite.

Abstract: An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode and/or electrode includes an electrode film having a super-fibrillized binder material and carbon. The electrode film can have a reduced quantity of the binder material while maintaining desired mechanical and/or electrical properties. A process for fabricating the electrode film may include a fibrillization process using reduced speed and/or increased process pressure such that fibrillization of the binder material can be increased. The electrode film may include an electrical conductivity promoting additive to facilitate decreased equivalent series resistance performance. Increasing fibrillization of the binder material may facilitate formation of thinner electrode films, such as dry electrode films.
