摘要: An energy storage apparatus suitable for mounting on a printed circuit board using a solder reflow process is disclosed. In some embodiments, the apparatus includes: a sealed housing body (e.g., a lower body with a lid attached thereto) including a positive internal contact and a negative internal contact (e.g., metallic contact pads) disposed within the body and each respectively in electrical communication with a positive external contact and a negative external contact. Each of the external contacts provide electrical communication to the exterior of the body, and may be disposed on an external surface of the body. An electric double layer capacitor (EDLC) (also referred to herein as an “ultracapacitor” or “supercapacitor”) energy storage cell is disposed within a cavity in the body including a stack of alternating electrode layers and electrically insulating separator layers. An electrolyte is disposed within the cavity and wets the electrode layers. A positive lead electrically connects a first group of one or more of the electrode layers to the positive internal contact; and a negative lead electrically connects a second group of one or more of the electrode layers to the negative internal contact.

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.

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.
