Problems solved by technology

Wang et al. (X.Wang, et al.ACS Appl.Mater., 2014,6,2583) developed a 3D printing process for the preparation of honeycomb metal materials catalyzed by a lead acetate initiator. However, the process is complex and the cost of 3D printers is relatively high. High, so the development of low-cost, new 3D porous electrode materials has become a top priority

Embodiment Construction

[0029] Attached below figure 1 The present invention is described further.

[0030] The three-dimensional porous nickel hollow fiber electrode material is a porous hollow tube as a whole, including a porous tubular three-dimensional base material and a nickel metal layer plated on the surface of the three-dimensional base material. Preferably, the three-dimensional base material is made of alumina particles; the three-dimensional porous nickel hollow fiber electrode material has an outer diameter of 1.8 mm, a thickness of 0.3 mm, and a pore diameter of 0.3-2 μm.

[0031] Based on the preparation method of the above-mentioned three-dimensional porous nickel hollow fiber electrode material, the steps are as follows:

[0032] Step 1: Making hollow fiber tubes with alumina particles as the base material, wherein the alumina particles are prepared by a phase inversion sintering process; the specific method is: adding polysulfone to the alumina particles with a particle size of 0.5...

Abstract

The invention discloses a three-dimensional porous nickel hollow fiber electrode material, a preparation method and a battery based on the electrode. The integral electrode material is of a porous hollow tube shape and comprises a porous tubular three-dimensional substrate material and a nickel metal layer plated to the surface of the three-dimensional substrate material. By combining a membrane process with an electroless deposition process in the preparation method, the prepared electrode material is uniform and controllable in hole diameter, and the surface area of the electrode material isfar greater than that of a two-dimensional electrode material. The microorganism attachment is improved favorably, the electricity generating capacity of a microbial fuel cell is improved, and the fuel cell prepared based on the electrode material is excellent in performance.

Description

technical field [0001] The invention relates to a new energy material, a preparation method thereof and a new energy battery, in particular to a three-dimensional porous nickel hollow fiber electrode material, a preparation method and a battery based on the electrode material. Background technique [0002] Microbial fuel cell (MFC), as a device that can use electrogenic bacteria to biodegrade organic matter to generate electricity, has shown great potential in sewage treatment and renewable energy production. Bruce E. Logan (Microbial Fuel Cell, 1st ed. John Wiley & Sons, Inc., Hoboken, 2007) found that about 1.5% of electricity production in the United States is directly used for sewage treatment, which has caused a great waste of energy utilization. However, on the other hand, domestic sewage contains a large amount of organic matter, and its contained energy is about 9 times that of sewage treatment energy consumption. The use of microbial fuel cells to treat domestic se...
