Problems solved by technology

[0008] In the lithium / thionyl chloride battery with the current structure, when the amount of active material and diaphragm added inside the battery is reduced, the battery core will inevitably loosen, and the single cathode lug and single anode lug and their welding methods cannot restrain the battery core. The looseness of the battery core is more harmful to the performance of the battery, especially the safety performance of the battery
The looseness of the battery core cannot meet the requirements of underground vibration and impact on the battery. The light one will cause the internal circuit break of the battery, and the severe one will cause the internal short circuit of the battery, and even cause the battery to burst
All of these may cause the drilling operation to be interrupted and forced to pull out the drill, seriously affecting the progress of oil production, geological exploration operations and the economic benefits of the drilling construction team.

Abstract

The invention relates to an impact resistant and vibration resistant lithium / thionyl chloride battery. The battery comprises a housing. The following components are orderly arranged in the housing, from bottom to top: a bottom insulating sheet, a battery core, an upper insulating sheet, a top insulating sheet, and a metal-glass top cap. Electrolyte is filled in the battery core. The battery core is in a structure of rolled layers. The battery core comprises orderly arranged components of: a separating membrane, a cathode sheet, another separating membrane, and an anode sheet. The metal-glass top cap is provided with a central column in the center. A cathode lead is connected with the central column. An arc transition is arranged on the edge of the lower surface of the metal-glass top cap.Anode leads are clamped and welded between the metal-glass top cap and the housing. There are at least two anode leads. The anode leads are annularly and uniformly distributed along the inner wall ofthe battery housing. The battery is suitable to be applied in oil exploitation and geological exploration engineering. The battery resists environmental probations of high temperatures, and impacts and vibrations of drilling bits and drill pipes. With the battery, the battery core is prevented from loosening.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a lithium / thionyl chloride (Li / SOCl 2 )Battery. Background technique [0002] Lithium / thionyl chloride (Li / SOCl 2 ) battery is a lithium as an anode, carbon as a cathode carrier, anhydrous lithium tetrachloroaluminate thionyl chloride (SOCl 2 ) solution as the lithium battery electrolyte.
