摘要:
An energy storage structure includes an energy storage device containing at least one porous structure (110, 120, 510, 1010) that contains multiple channels (111, 121), each one of which has an opening (112, 122) to a surface (115, 116, 515, 516, 1015, 1116) of the porous structure, and further includes a support structure (102, 402, 502, 1002) for the energy storage device. In a particular embodiment, the porous structure and the support structure are both formed from a first material, and the support structure physically contacts a first portion (513, 813, 1213) of the energy storage device and exposes a second portion (514, 814, 1214) of the energy storage device.
摘要:
Methods of increasing an energy density of an energy storage device involve increasing the capacitance of the energy storage device by depositing a material into a porous structure of the energy storage device using an atomic layer deposition process, by performing a procedure designed to increase a distance to which an electrolyte penetrates within channels of the porous structure, or by placing a dielectric material into the porous structure. Another method involves annealing the energy storage device in order to cause an electrically conductive substance to diffuse to a surface of the structure and form an electrically conductive layer thereon. Another method of increasing energy density involves increasing the breakdown voltage and another method involves forming a pseudocapacitor. A method of increasing an achievable power output of an energy storage device involves depositing an electrically conductive material into the porous structure.

An energy storage device comprises at least one porous structure (500, 900) containing multiple channels (510), each one of which has an opening to a surface (505) of the porous structure. Each one of the channels has a first end (511) having a first average width (513) and a second end (512) having a second average width (514), with the first end being located where the channel opens to the surface of the porous structure and the second end being located at a distance from the first end as measured along a length of the channel. For at least some of the channels, the first average width is larger than the second average width.
