Description
Technical field
The present invention relates to the technical field of battery, be meant a kind of lithium/thinly chloride battery especially.
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 increasingly high 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 bottom insulation sheet, battery core body, top insulating trip and metal-glass from bottom to up successively and seals up lid, is perfused with electrolyte in the battery core body; The battery core body is a multilayer web-like structure; Comprise barrier film, negative electrode pole piece, barrier film and anode pole piece successively, barrier film is non-woven glass fiber, and 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, and the center that metal-glass is sealed up lid is provided with newel, and 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 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; In addition; An anode lug is welded on the battery container inwall; Also possibly there is rosin joint in not only operation inconvenience, 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.Simultaneously; 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, decomposes, gasify and the swelling that causes battery, strengthened the possibility that the battery core body becomes flexible 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, and 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 the shock and vibration that can also bear drill bit, drilling rod simultaneously suppress the battery core body and loosening vibration resistance, the lithium/thinly chloride battery of impact occur.
For addressing the above problem; The technical scheme that the present invention adopts is: the lithium/thinly chloride battery of a kind of vibration resistance, impact; Comprise a housing; The inside of housing is disposed with bottom insulation sheet, battery core body, top insulating trip, support ring, top insulating trip and metal-glass from bottom to up and seals up lid, is perfused with electrolyte in the battery core body, between top insulating trip and top insulating trip, is provided with support ring.
The height of described support ring is less than or equal to the distance between top insulating trip and the top insulating trip.
The bottom of said support ring is connected with the top insulating trip, and the top of support ring is connected with the top insulating trip.
The external diameter of said support ring is not more than the internal diameter of housing, and the internal diameter of support ring is not less than the diameter of newel.
