Abstract
The utility model relates to an air electrode performance recovery device for an air battery. The air electrode performance recovery device comprises a lead for connecting an air battery electrode, and is characterized in that: the lead is embedded into a cover cap; one end of the lead is positioned in the inner cavity of the cover cap, and the other end of the lead is positioned outside the cover cap; a bottom plate is detachably connected to the bottom of the cover cap, and is provided with an annular groove; and the cover cap is buckled in the annular groove. Due to the adoption of the structure of the device, the airtightness is ensured, convenience is brought to replacement of the battery, and the battery can be replaced only by lifting the cover cap, taking the battery out, changing a new battery, coating Vaseline in the annular groove and sealing.
Description
Technical field
The utility model relates to a kind of air pole performance recovery device of air cell.
Background technology
Because the significantly lifting of the battery performance that has very big specific area and bring thus, gas-diffusion electrode is extensively adopted as metal-air battery and fuel cell electrode.Yet in long use, will occur inevitably descending owing to receive the performance that influences gas-diffusion electrode of various factors.As discharging through multiple cycles, activity of such catalysts can reduce, and catalyst granules can spread with the diffusion of materials such as water and proton in gas electrode inside simultaneously; For alkaline battery, alkali lye can form carbonate after having absorbed carbon dioxide in air, and gas-liquid duct in the electrode is stopped up in its crystallization meeting, and then causes declining to a great extent of electrode reaction efficient.
Improve the gas-diffusion electrode method of life at present and can be divided into two kinds: be a kind of through improvement raising electrode life to electrode material, catalyst; Like Chinese patent 200510032676.X disclosed " a kind of preparation method of zinc-air cell eelctro-catalyst "; Introduced a kind of preparation method of zinc-air cell eelctro-catalyst; Take by weighing Li, Mn, Co metal soluble salt by a certain percentage, heating behind the adding solvent solution-forming, oven dry, heat treatment obtains eelctro-catalyst; Thereby another kind of method through improvement electrode manufacture craft change electrode structure reaches the purpose that improves electrode life; Having introduced a kind of like " functional material " fourth phase in 2006 disclosed " sintering is to the life-span of air electrode and the influence of microcellular structure " is raw material with active carbon, acetylene black, PTFE emulsion, the method that sintering is made air electrode in inert gas after the roll-in.First method relates to new material, Preparation of catalysts electrode life through the improvement of electrode material, catalyst is improved; Cost of manufacture is higher; Be unfavorable for popularizing, its corresponding subsequent technology such as material recovery etc. need be carried out corresponding supporting exploitation simultaneously, drop into bigger; Second method changes the manufacture craft of electrode also need develop corresponding manufacturing and processing equipment, needs bigger input equally.Under sealed environment, utilize discharge instrument that air cell is carried out the discharge of appropriateness, can realize the significantly rise of electrode performance, improve it and recycle the life-span, practiced thrift production cost.This just needs a kind of device simple in structure, easy to use, can air cell be sealed in wherein.
Summary of the invention
The purpose of the utility model provides a kind of air pole performance recovery device of simple air cell; To the gas-diffusion electrode performance decrease that various factors causes, need not electrode material and manufacture craft improved to significantly improve electrode performance.
For achieving the above object, the utility model adopts following technical scheme:
The air pole performance recovery device of the described air cell of the utility model; Comprise the lead that is used to connect the air cell electrode; It is characterized in that: said lead is inlaid on the cover cap, and an end of lead is arranged in the cover cap inner chamber, and the other end of lead is positioned at the outside of cover cap; The bottom of cover cap removably connects base plate, and base plate is provided with annular groove, and cover cap is fastened in the annular groove.
Owing to there has not been the participation reaction of oxygen, in fact battery is in the state of a kind of " reverse charge " under sealed environment, and meeting exciting electrode catalyst is owing to repeatedly using the activity that descends; Simultaneously, the crystallization salt that stops up the porous electrode micro channel can be decomposed and be ionic condition, and the diffusion of porous electrode thereby be restored is the place that provides with reaction of passing through of gas.The comprehensive function of this two aspect is gone up electrode performance.The structure of device has guaranteed sealing, has also made things convenient for the replacing of battery, when changing, only needs cover cap is uncovered, and takes out battery and changes new battery, in annular groove, smears the vaseline sealing again and gets final product.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
The air pole performance recovery device of the said air cell of the utility model comprises the lead 4,5 that is used to connect the air cell electrode, and said lead 4,5 is inlaid on the cover cap 2, and an end of lead 4,5 is arranged in cover cap 2 inner chambers, is used to connect the electrode of air cell; The other end of lead 4,5 is positioned at the outside of cover cap 2, is used to connect discharge instrument; The bottom of cover cap 2 removably connects base plate 1, and base plate 1 is provided with annular groove 3, and cover cap 2 is fastened in the annular groove 3.Said cover cap 2 can adopt rectangular box-shaped structure, also can adopt cylindrical structure or hemisphere shell-like structure.
During use, air cell is placed in the cover cap 2, the inside and outside end of lead 4,5 is connected with air cell and discharge instrument respectively, in annular groove 3, smear vaseline, make cover cap 2 and the sealing of base plate 1 junction.Constant-current discharge through after a while can increase substantially the air pole performance of air cell.
