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.
