Title: Mxene layer coated hydrophilic fiber membrane based electrokineticic power generator and manufacturing method thereof
IPC: H02N11/00
Filed: 2021-03-23
Abstract: Embodiments of the present invention relate to a new-concept composite power generator and a manufacturing method thereof, capable of performing high-efficiency power generation by applying a polar solution to the composite power generator including a hydrophilic fiber membrane coated with an MXene layer. In detail, an apparatus for generating electrical energy based on a hydrophilic fiber membrane coated with an MXene layer forms the MXene layer by uniformly applying MXene particles to a fiber strand surface of the hydrophilic fiber membrane through a dipping process. The polar solution is dropped only on a region where one of two electrodes connected to the hydrophilic fiber membrane coated with the MXene layer is connected so as to generate the electrical energy by using a potential difference formed by asymmetric wetting of a solvent. The hydrophilic fiber membrane having a large surface area and high polar solvent absorption allows the MXene particles to be applied over an area as wide as possible and absorbs a polar solvent for a long time, so that an electric double layer and a potential difference between the polar solvent and the MXene particles are efficiently formed for a long time. In particular, the electrical energy is generated for 1 hour or more only by dropping a small amount (0.25 ml) of the polar solvent on a surface of the apparatus for generating the electrical energy based on the hydrophilic fiber membrane coated with the MXene layer. The apparatus for generating the electrical energy based on the hydrophilic fiber membrane coated with the MXene layer increases a voltage and a current in forms of stacking, series, or parallel. A DC power generated in the above process is stored in a super capacitor and used in a high-power electronic device.
