ENERGY STORAGE DEVICE, ANODE THEREOF, AND METHOD OF FABRICATING AN ENERGY STORAGE DEVICE

摘要

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.
