    摘要： An electric double layer capacitor (EDLC) is disclosed including: a first electrode including a first current collector and first plurality of carbon nanotubes (CNTs) disposed substantially directly upon the first current collector; a second electrode comprising a second current collector and second plurality of CNTs disposed substantially directly upon the second current collector; and an electrolyte disposed between and in contact with (e.g., wetting) the first and second electrodes. In some embodiments, the EDLC is configured to have a capacitive frequency window comprising about 1 Hz to about 50 Hz.

    摘要： A thermal interface material is disclosed. The material includes: a sheet extending between a first major surface and a second major surface, the sheet including: a base material; and a filler material embedded in the base material. The base material may include anisotropically oriented thermally conductive elements. In some embodiments, the thermally conductive elements are preferentially oriented along a primary direction from the first major surface towards the second major surface to promote thermal conduction though the sheet along the primary direction. In some embodiments, the base material is substantially free of silicone. In some embodiments, the thermal conductivity of the sheet along the primary direction is at least 20 W/mK, 30 W/mK, 40 W/mK, 50 W/mK, 60 W/mK, 70 W/mK, 80 W/mK, 90 W/mK, 100 W/mK, or more.

    摘要： An electrode active layer is disclosed that includes a network of high aspect ratio carbon elements (e.g., carbon nanotubes, carbon nanotube bundles, graphene flakes, or the like) that provides a highly electrically conductive scaffold that entangles or enmeshes the active material, thereby supporting the layer. A surface treatment can be applied to the high aspect ratio carbon elements to promote adhesion to the active material and any underlying electrode layers improving the overall cohesion and mechanical stability of the active layer. This surface treatment forms only a thin (in some cases even monomolecular) layer on the network, leaving the large void spaces that are free of any bulk binder material and so may instead be filled with active material. The resulting active layer may be formed with excellent mechanical stability even at large thickness and high active material mass loading.
