Abstract

A nitrogen-containing porous carbon material, and a capacitor and a manufacturing method thereof are provided. A carbon material, a macromolecular material and a modified material are mixed into a preform. The modified material includes nitrogen. A formation process is performed on the preform to obtain a formed object. High-temperature sintering is performed on the formed object to decompose and remove a part of the macromolecular material, while the other part of the macromolecular material and the carbon material together form a backbone structure including a plurality of pores. As such, the nitrogen becomes attached to the backbone structure to form a hydrogen-containing functional group to further obtain the nitrogen-containing porous carbon material. The nitrogen-containing porous carbon material may form a first nitrogen-containing porous carbon plate and a second nitrogen-containing porous carbon plate, which are placed in seawater to form a storage capacitor for seawater. The problem that the performance of the conventional porous carbon materials cannot be further improved can be solved.

Description

technical field [0001] The invention relates to a porous carbon material, in particular to a nitrogen-containing porous carbon material, a capacitor and a manufacturing method thereof. Background technique [0002] Porous carbon materials refer to carbon materials with different pore sizes, and their pore sizes can range from nano-scale pore sizes equivalent to molecular sizes to micron-scale pore sizes suitable for microbial proliferation and activities, and porous carbon materials are durable. With a series of advantages such as high temperature, acid and alkali resistance, electrical conductivity, and heat transfer, it has been widely used in gas and liquid refining, water treatment, air purification, catalytic materials, electronic energy materials, bioengineering materials, etc. [0003] Porous carbon materials such as the Porous carbonmaterial and manufacturing method thereof and supercapacitor in US Patent Publication No. US 2014 / 0118884, which discloses a porous carb...
