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.
