Fig. 2 is the structural representation that the present invention launches electrical storage device;
Fig. 3 is the schematic cross-section of gas absorption body when cutting off along the cutting line A-B in Fig. 2.
Embodiment
Agricultural machinery electric storage device comprises accumulator plant, charging device and charge and discharge control mechanism, electrical storage device connects charging device, and accumulator plant comprises exterior member, the positive pole negative pole opposed with described positive pole, electrolyte between described positive pole and described negative pole; And sorbing material, wherein, described positive pole, described negative pole, described electrolyte and described sorbing material are arranged in described exterior member, between described electrolyte and described sorbing material, be provided with chorista, further, described chorista do not make described electrolyte through and make gas permeation.
As shown in Figure 1, electrical storage device 100 comprises exterior member 103, is sealed with power storage body 101 and gas absorption body 102 in exterior member 103.At this, apply membranaceous laminated film as exterior member 103.In addition, the formation positive pole 104 of power storage body 101 and a part for negative pole 105 are exposed to the outside of exterior member 103, and are used as terminal.
As shown in Figure 2, be the schematic diagram launching electrical storage device 100.
Power storage body 101 comprises positive pole 104, negative pole 105 and configuration slider 106 between which, also at least between positive pole 104 and negative pole 105, comprises electrolyte.Further, gas absorption body 102 is configured with in the mode overlapping with power storage body 101.
Positive pole 104 is used as the positive pole of power storage body 101, and at least comprises positive active material.In addition, negative pole 105 is used as the negative pole of power storage body 101, and at least comprises negative electrode active material.Positive pole 104 and negative pole 105 can all comprise collector, conductive auxiliary agent and binding agent etc.
Slider 106 is arranged to make positive pole 104 directly not contact with negative pole 105.In addition, use as slider 106 chemical stability that has for electrolyte and make electrolyte through material.
Electrolyte at least has electrolyte and dissolves this electrolytical solvent.Also electrolyte can be set to the state in slider 106 of infiltrating.
Gas absorption body 102 comprises sorbing material 111 and is arranged on the chorista 112 between sorbing material 111 and electrolyte.This sorbing material 111 adsorbed gas.This chorista 112 do not make electrolyte through and make gas permeation.
Chorista 112 has does not make penetration by liquid (infiltration) and the function making gas permeation.As chorista 112, the transmitance that such as can use the object gas (such as carbon dioxide) under normal condition is 0.1 [g/m
2day] more than, be preferably more than 1 [g/m2day], be more preferably the material of more than 10 [g/m2day].In addition, because gas permeation rate depends on material and the thickness of chorista 112, so the material of suitable setting chorista 112 or thickness are to make it have suitable gas permeation rate.Fig. 3 is the schematic cross-section of gas absorption body 102 when cutting off along the cutting line A-B in Fig. 2.Gas absorption body 102 comprises the chorista 112 that its inside has space, comprises multiple granular sorbing material 111 in this space.Adopt by chorista 112 make sorbing material 111 not with the structure of electrolyte contacts.At this, the negative pole 105 as electrical storage device 100 applies the material that electrode potential is extremely low compared with positive pole 104, so its reducing power is strong.Therefore, a part for electrolyte is reduced decomposition and on negative pole 105, forms the overlay film of catabolite.Moreover the part being reduced the electrolyte of decomposition becomes gas sometimes and stays electrical storage device 100 inside.In addition, during the voltage height used in positive pole 104 side (when ratio forms the decomposition voltage height of the solvent of electrolyte), electrolyte also similarly can decompose and produce the gas comprising the element forming electrolyte sometimes.
This gas is impurity concerning electrical storage device 100, and likely becomes the principal element causing various deterioration.Such as when occurred gas is the gas of oxidizability or reproducibility, likely react with exterior member 103 inside, positive pole 104, negative pole 105 or slider 106 etc. and they are corroded.In addition, this gas stays the migration that can hinder charge carrier between positive pole 104 and negative pole 105.In addition, also following bad phenomenon likely occurs: the gas produced makes by the pressure increase of the electrical storage device inside sealed, the framework of electrical storage device expands, even electrical storage device damage or blast etc.Electrical storage device 100 shown in this configuration example when a part for electrolyte be reduced decompose and produce gas can by this gas absorption through chorista 112 in sorbing material 111.Its result, can reduce the gas stayed in electrical storage device 100, therefore can reduce the generation of above-mentioned bad phenomenon, thus realizes the high electrical storage device of reliability.
