Description

A kind of metal-air battery of the generating that gets wet

Technical field

The utility model belongs to cell art, more particularly to a kind of metal-air battery of the generating that gets wet.

Background technology

The metal-air battery occupation mode that existing multilayer is stacked is got wet when using, and allows suction between positive/negative plate Water material fully gets wet after moistening, makes positive and negative interpolar start to produce chemical reaction and produce electric energy.The purpose just got wet when using It is such battery is had a stable storage condition before being not used, just will not be in advance put using preceding because of from loss problem It is complete electricity and fail, it is adaptable on the disaster prevention emergency product of long term storage.

And the shell of the battery that the multilayer for coating such metal-air battery is stacked is then each different, some are only letters Easy gummed paper voluble wrapping, some then have firm plastic casing to protect, and are fabricated to after a metal-air battery for multilayer again It is placed into the power device to be used.And the multilayer that these prior arts are done stacks metal-air battery and has common common Structural disadvantage：

1. excessively consolidation is coated, and is short of and is considered expansion space：Because the metal-air battery that multilayer is stacked need to make it is positive and negative Level is brought into close contact, so needing to compress multilayer both positive and negative polarity during cladding, either shell is gummed paper, shrink film, soft ebonite jar Or other, all it is enveloping tightly.This can cause to get wet gradually produce metal oxide and body using rear active metal piece Product expansion, the volume for strutting has several risks, causes the battery that content overflows, is stuck in power device to accommodate comprising shell is racked The problems such as cannot being taken out in cavity.

2. there is the slit for adding water and breathing freely on battery case, metal oxide residue can be made easily to be scattered：After oxidation reaction Metal oxide residue have part can be clipped in positive/negative plate between, some oxide residues near edge then can be via battery mould The slit for being added water on block shell/being breathed freely is dropped out.These residues may be scattered in the inside of power device and influence performance；Also may be used Can be scattered in user causes dirty perception on hand.

3. it is all tailored version that existing multilayer stacks metal-air battery, is short of general and interchangeable design：It is numerous many Layer stacks metal-air battery and is all only applicable in single power device, is melted using bonding wire, heat, the fixed form such as gluing, it is impossible to It is convenient to take out and change, replacings therefore often cannot be disassembled when dead battery capability, and must whole device discarding and make Into waste and pollution.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of metal-air battery of the generating that gets wet, it is intended to solved Structural disadvantage existing for metal-air battery certainly of the prior art.

The utility model embodiment provides a kind of metal-air battery of the generating that gets wet, including battery, both positive and negative polarity are led Electric piece and shell, the battery are embedded in the shell, and it includes the metal chip that polylith is stacked, the metal-air Battery also includes bolster and for permeable and ventilative filtration members, and the bolster and filtration members are embedded at described respectively Between the not ipsilateral of battery and the inwall of the shell, also, the battery and both bolsters contact surface Expansion direction that is vertical or favouring battery；Offered on the shell wall body relative with the filtration members for adding water and Ventilative hole.

Further, the bolster is soft liner, and the filtration members are fiber membrane.

Further, the battery have the vertical side vertical with its expansion direction, the vertical side with it is described Described bolster is equipped between outer casing inner wall；The battery has the parallel side parallel with its expansion direction, described Described filtration members are equipped between parallel side and the outer casing inner wall.

Further, the shell and battery are in rectangular-shape, and the thickness direction of the battery expands for it Direction, the vertical side includes leading flank and trailing flank, and the parallel side includes top surface and bottom surface；The battery Leading flank and the antetheca of shell between be equipped with described bolster, between the trailing flank of the battery and the rear wall of shell It is equipped with described bolster；Described filtration members, the electricity are equipped between the top surface of the battery and the roof of shell Described filtration members are equipped between the bottom surface of Chi Xin and the bottom wall of shell.

Further, the shell includes thering is open slot, the battery, mistake in upper lid and housing, the housing Filter part and bolster are embedded in the open slot, and the upper lid is fastened with the notch of the open slot.

Further, mounting groove is additionally provided with the housing, one end of the both positive and negative polarity conducting strip is installed on the peace In tankage, its other end stretches out the housing.

Compared with prior art, beneficial effect is the utility model：The metal-air of the generating that gets wet of the present utility model Battery, it has set bolster between battery and shell, and the metal chip inside battery gradually produces metal oxidation Thing and during volumetric expansion, battery extruding soft liner, so that bolster deformation is stepped down, for its expansion provides space, it is to avoid Battery racks shell and causes that content overflows and battery is stuck in the battery receiving cavity of power device what cannot be taken out Problem.Meanwhile, offered on shell for adding water and permeable hole, can add water from different directions, hole also provides saturating simultaneously Gas, the oxygen needed for enabling oxidation reaction is supplemented.Due to being also equipped with filtration members between battery and shell, the filtration members can Metal oxide residue is avoided to drop out.Prevent residue to be scattered in power device inside and influence its performance, also prevent residue It is scattered in the perception that user causes dirt on hand.
