ULTRACAPACITORS COMPRISED OF MINERAL MICROTUBULES

摘要

An ultracapacitor (2200) comprising a first electrode (2110) containing mineral microtubules, a second electrode (2210) containing mineral microtubules, an electrolyte (2030) disposed between the first electrode (2110) and the second electrode (2210), and a separator (2040) disposed in the electrolyte to provide electrical insulation between the first electrode (2110) and the second electrode (2210), while allowing ion flow within the electrolyte (2030). The electrodes may be formed from a paste containing mineral microtubules, or may consist essentially of a conductive polymer containing mineral microtubules, or an aerogel containing the mineral microtubules. The mineral microtubules may be filled with carbon, a pseudocapacitance material, or a magnetoresistive material. The mineral microtubules may also be coated with a photoconductive material.
