Description
Technical field
The present invention relates to field of batteries, be meant a kind of lithium/thinly chloride (Li/SOCl especially
2) battery.
Background technology
Lithium/thinly chloride (Li/SOCl
2) battery be a kind of be anode with the lithium, carbon is made cathode carrier, the thionyl chloride (SOCl of anhydrous tetrachloro-lithium aluminate
2) solution makes the lithium battery of electrolyte.Lithium/thinly chloride battery has characteristics such as specific energy height, specific power are big, discharging voltage balance, temperature applicable range is wide, storage life is long, in military and civilian industry such as Aero-Space, underawater ordnance, navigator, geological prospecting, instrument and meter, all is widely used.Lithium/thinly chloride battery is specific energy and the highest a kind of battery of specific power in the current battery field.
Above excellent specific property is arranged just, and in recent years, lithium/thinly chloride battery is used widely in oil exploitation, geological prospecting.In oil exploitation, geological prospecting engineering; Need be to intending exploitation or the enforcement boring of prospecting zone; On the one hand the track in this length of creeping into is measured, on the other hand the environmental aspect in this length of creeping into is measured, to gather and to write down various floor datas.And serve as the power of gathering and writing down various floor datas, be lithium/thinly chloride battery.
Lithium/thinly chloride battery is underground along with the underground survey appearance progressively gets under drill bit, drilling rod drive, and not only will bear more and more higher temperature test, impact and the vibrations that also will bear drill bit, drilling rod simultaneously.According to the relevant criterion requirement, want to bear the environmental test of-40 ℃ ~ 175 ℃ of temperature with the battery tube that brill is gone into the well, can also bear vibration acceleration 196m/s simultaneously
2(swept frequency range 20Hz ~ 200Hz, sweep speed is 1oct/min), impact acceleration 455m/s
2, the harsh operating mode test of semisinusoidal waveform 11ms.
At present, domesticly be used for the battery tube that the While-drilling down-hole measurement appearance is gone into the well, use the improved slightly lithium/thinly chloride battery of domestic production mostly.The structure of existing lithium/thinly chloride battery is: comprise a housing; The inside of housing is placed with the bottom insulation sheet from bottom to up successively; The battery core body; Top insulating trip and metal-glass are sealed up lid; Be perfused with electrolyte in the battery core body; The battery core body is a multilayer web-like structure; Comprise barrier film successively; The negative electrode pole piece; Barrier film and anode pole piece; Barrier film is non-woven glass fibre; The negative electrode pole piece is that carbon and polytetrafluoroethylene binding agent and nickel draw in the net to close film; Anode pole piece is that lithium and nickel draw in the net to close film; The bottom that metal-glass is sealed up lid is placed with the top insulating trip; The center that metal-glass is sealed up lid is provided with newel; A cathode tab directly is welded on the newel; An anode lug is welded on the inwall of housing, or folder is welded in metal-glass and seals up in lid and the crack of housing.
The lithium/thinly chloride battery of existing structure, not only resistance to elevated temperatures is difficult to satisfy the environmental test of down-hole higher temperature, and its immanent structure also is difficult to satisfy the harsh operating mode test of underground vibrating, impact.This is because at first, the play that is difficult to satisfy the battery core body as the cathode tab of monopole ear is split vibrations, impact and might sealing-off or fracture; Split vibrations in the play of battery core body, impact and the ability sealing-off is also arranged down or fracture as the anode lug of monopole ear; Secondly; An anode lug is welded on the battery container inwall; Not only operation inconvenience; Also possibly there is rosin joint; And anode lug folder is welded in metal-glass and seals up the production technology in the crack of lid and housing; Can cause metal-glass to seal up the decentraction of lid and housing again, the consistency of girth welding is reduced; The 3rd; Because metal-glass is sealed up lid and is generally cylindrical structure, the anode lug is being clipped in metal-glass when sealing up in the crack of lid and housing, it is tangent that metal-glass is sealed up the edge, lower surface and the battery container port of lid; Easily the anode lug is cut off, thereby cause rosin joint.
In addition; Some battery production enterprises are in order to overcome the influence of down-hole higher temperature to battery; Adopt the addition that reduces inside battery active material and barrier film; To increase the redundant space of inside battery; Slow down electrolyte and under hot environment, decompose, gasify and the swelling that causes battery, strengthened the loosening possibility of battery core body again.
The lithium/thinly chloride battery of existing structure; When the addition that reduces inside battery active material and barrier film; Certainly lead to the loosening of battery core body; And single cathode tab and single anode ear and welding manner thereof; Can't suppress the loosening of battery core body again, the loosening security performance harm to the performance of battery, especially battery of this battery core body is bigger.Becoming flexible of battery core body can't be satisfied underground vibrating, impacted the requirement to battery, and the lighter causes inside battery to open circuit, and weight person causes internal short-circuit of battery, even causes the battery explosion.These all possibly cause drillng operation to interrupt and compelled the trip-out, and tight amount influences the economic benefit of oil exploitation, geological prospecting job scheduling and wellbore construction troop.
Summary of the invention
Technical problem to be solved by this invention is: a kind of temperature test that can not only bear-40 ℃ ~ 175 ℃ is provided, and impact and the vibrations that can also bear drill bit, drilling rod simultaneously suppress the lithium/thinly chloride battery that loosening shock-resistant, vibration appears in the battery core body.
For addressing the above problem; The technical scheme that the present invention adopts is: a kind of shock-resistant; The lithium/thinly chloride battery of vibration; Comprise a housing; The inside of housing is disposed with the bottom insulation sheet from bottom to up; The battery core body; The top insulating trip; Top insulating trip and metal-glass are sealed up lid; Be perfused with electrolyte in the battery core body; The battery core body is a layer web-like structure; Comprise barrier film successively; The negative electrode pole piece; Barrier film and anode pole piece; Barrier film is non-woven glass fibre; The negative electrode pole piece is that carbon and polytetrafluoroethylene binding agent and nickel draw in the net to close film; Anode pole piece is that lithium and nickel draw in the net to close film; The center that metal-glass is sealed up lid is provided with newel; Cathode tab is connected with newel; The lower surface edge that said metal-glass is sealed up lid is provided with arc transition; Anode lug folder is welded in metal-glass and seals up between lid and the housing, and described anode lug is provided with two at least, and the anode lug evenly distributes along wall circular in the battery container.
Described anode pole piece is provided with 2 ~ 6 anode lugs.
The invention has the beneficial effects as follows: the lithium/thinly chloride battery of above-mentioned a kind of shock-resistant, vibration; Adopt the multianode lug; Can not only strengthen metal-glass and seal up lid and housing concentricity, thereby the quality of girth welding is effectively improved, increase the input and output rate of battery; The more important thing is; Battery core body and battery container closely can be fused; Controlled the loosening of battery core body; Protected inside battery cathode tab and anode lug to avoid damage effectively; Having stopped battery takes place because of the phenomenon that the down-hole is impacted, vibration causes internal break, internal short-circuit; Effectively guarantee the progress of oil exploitation, geological prospecting operation, promoted the economic benefit of wellbore construction troop greatly.
