Problems solved by technology

However, the electrochemical aluminum plating method uses expensive reagents such as aluminum-containing ionic liquids, and requires the system not to contain any water, so as to avoid the decomposition of ionic liquids, the formation of various strong corrosive substances and acid mist, and the removal of raw materials and systems. rising water costs
The pure physical sputtering method overcomes the shortcomings of electrochemical aluminum plating, but its equipment is limited in size and cannot realize simultaneous sputtering of large-area samples, and the aluminum deposition rate is too slow
In addition, there is a method of high-temperature physical vaporization of aluminum in the industry, but high-temperature aluminum vapor will directly cause the melting of porous polyurethane film, and no qualified samples can be obtained.
At the same time, compared with porous nickel and porous copper, porous aluminum has insufficient mechanical strength, which leads to poor performance in continuous processing, significantly reduces the efficiency of large-scale industrial production, and increases manufacturing costs.

Description

Technical field [0001] The invention belongs to the technical field of electrochemical energy storage and metal processing, and particularly relates to a porous aluminum or a composite of aluminum and other metals used in an electrochemical energy storage system and a manufacturing system and method. Background technique [0002] At present, various types of secondary battery supercapacitors are a hot research field and a large application market for clean electrochemical energy storage in the world. The common structural characteristics of these energy storage systems are that they have active materials, positive and negative electrodes, and separators. fluid. Traditional processing methods often use non-porous, flat, mechanically strong, and conductive metal foils (such as aluminum foil and copper foil) as current collectors. And in order to increase the mass share of the active material in the device as much as possible, the active material and the adhesive are often fixed on...
