Description
Technical field
The present invention relates to field of batteries, particularly a kind of metal air fuel cell.
Background technology
Traditional fossil energy not only resource reserve is limited, and in use brings a large amount of emissions, and this makes energy shortage and environmental pollution be that current social develops the two large outstanding problems faced.One of solution is exactly development of new alternative fuel.The electric power such as water energy, wind energy, solar energy as clean energy resource is difficult to directly directly use on electrical appliance, needs could use as carrier through energy storage material, so development of new battery becomes the key of new forms of energy development.
Metal air fuel cell is the battery of a kind of active metal as fuel, because it has very high energy density and specific power, lower cost, to advantages such as environment nontoxic pollution-frees, to be considered to " green energy resource geared to the 21st century ".The active material of positive electrode that metal-air cell is battery with active metal as lithium, calcium, magnesium, aluminium, iron, zinc etc., with the active material of cathode that the oxygen in air is battery, mainly with alkalescence or neutral aqueous solution be electrolyte, in discharge process, generate corresponding metal hydroxides.These hydroxide come off from surface of metal electrode with sedimentary form in the electrolytic solution, are settled down to battery bottom.Current technology is by scavenger precipitation thing during periodic replacement electrolyte.Because the metal anode of metal-air cell and air cathode distance can not be too far away, in most cases, gap between anode and negative electrode is smaller, if the precipitation of hydroxide that surface of metal electrode produces comes off from electrode surface not in time, but continue too much to be deposited in below metal anode and air cathode at the precipitate particles of electrode surface growth or generation, then as easy as rolling off a logly cause internal short-circuit of battery, affect battery supplying power for outside.This makes the electrolyte replacement cycle of metal current air cell shorter, and the maintenance cost causing battery to use is higher.
Summary of the invention
For the technical problem of above-mentioned existing metal-air cell, the invention provides that a kind of anodic deposition thing is easy to get rid of, the longer and metal air fuel cell that use cost is lower of maintenance period.
The technical scheme that the present invention solves the problems of the technologies described above is: comprise housing, positive electrode cap, negative pole cap, the metal electrode as anode, the air electrode as negative electrode and electrolyte cavities, be provided with the dividing plate of central aperture in described housing, housing is divided into upper and lower two parts by described dividing plate; Described metal electrode is that inverted cone-shaped is located at housing upper, and case top is fixed in the upper end of described metal electrode, and positive electrode cap is directly connected with metal electrode, and the lower end of described metal electrode is relative with dividing plate perforate; Described air electrode is correspondingly relative with the metal electrode conical surface in conical surface shape, and the upper end of air electrode is connected with the negative pole cap of case top, and lower end is connected with dividing plate; Described housing upper sidewall offers multiple pore, and case top establishes electrolyte filling mouth, and described housing bottom establishes leakage fluid dram.
In the metal air fuel cell of above-mentioned band cone-shaped metal anode, described metal electrode is metal or metal alloy.
In the metal air fuel cell of above-mentioned band cone-shaped metal anode, described air electrode comprises current collector layers and catalyst layer.
Owing to adopting technique scheme, beneficial effect of the present invention is: the present invention adopts pyramidal structure, and the space that metal electrode and air electrode are formed is long and narrow, is convenient to anodic deposition thing and drops; The lower electrolyte cavities of lower housing portion, can store a large amount of under gravity from the reaction precipitation thing that electrode surface is peeled off, thus avoid the deposit buildup of anode surface, the large buffer memory of same electrolyte cavities at present can improve the stability of battery and extend the maintenance period of battery, thus reduces use cost; Leakage fluid dram can ensure the timely eliminating of sediment and waste electrolyte, prevents precipitate bulk from causing battery short circuit between the anode and cathode.
