Abstract
The utility model relates to a cell, particularly a lithium-thionyl chloride cell. The utility model comprises an anode nail which is led from a carbon package, a cathode lithium slice which is contacted with a metal outer shell, side membranes which are arranged between the carbon package and the lithium slice, and bottom membranes which are arranged between the carbon package and the cathode bottom. The utility model is characterized in that the membrane is 2-5 layers. The utility model has the advantages of high temperature resistance, high voltage resistance, vibration resistance, impact resistance, etc.
Description
The utility model relates to a kind of battery, especially lithium---thionyl chloride battery.
Existing lithium---thionyl chloride battery comprises: follows closely from the positive pole that the carbon bag is drawn, and with the contacted negative pole lithium of metal shell sheet, the limit barrier film and the end barrier film that between carbon bag and lithium sheet and carbon bag and negative pole bottom, are provided with respectively.The effect of barrier film is an insulating electron, but allows ion pass and prevent that carbon dust from contacting and short circuit with the lithium sheet.And be in when working in the environment such as high temperature, high pressure, vibration or impact when battery, often, barrier film made battery life cross early stopping because of losing efficacy.
For this reason, the purpose of this utility model is to provide a kind of battery, and it can overcome the deficiency of above-mentioned prior art and adapt to described abominable operational environment.
The technical scheme that realizes the utility model purpose is when comprising aforementioned formation, and its distinctive feature is: barrier film is 2～5 layers.
And barrier film can be glass fibre or polypropylene mat.
In this formation, owing to change single-layer septum into 2～5 layers, increased the inherent mechanical strength of battery, and solved people and often think that membrane thicknesses can only be 0.1～0.2mm, and increased the anxiety that its thickness promptly can influence ion penetration.This battery can adapt to operational environments such as high temperature, high pressure, vibration or impact, already use through oil drilling to show, when entering depths, the face of land with drill bit and use for transducer, it always operate as normal exhaust to electric energy.
The utility model is described in further detail below with reference to accompanying drawing.
Accompanying drawing is the cutaway view of this battery.
With reference to accompanying drawing, lithium described in the utility model---thionyl chloride battery comprises: follow closely 1 from the positive pole that carbon bag 6 is drawn, with metal shell 3 contacted negative pole lithium sheets 4, the limit barrier film 5 and the end barrier film 7 that between carbon bag 7 and lithium sheet 4 and carbon bag 7 and negative pole bottom 8, are provided with respectively.Wherein, shell 3 can adopt stainless steel, is heat shrinking sleeve 2 outside the shell 3.
In order to increase its inherent mechanical strength, barrier film 5,7 is 2～5 layers.
The material of making barrier film 5,7 can adopt glass fibre or polypropylene mat.Usually can select all-glass paper or glass fabric for use, when manufacturing, all-glass paper (fabric) is cut into the strip bigger slightly than electrode.
Claims (2)
1, a kind of battery, especially lithium---thionyl chloride battery, comprise: follow closely [1] from the positive pole that carbon bag [6] is drawn, with metal shell [3] contacted negative pole lithium sheet [4], the limit barrier film [5] and the end barrier film [7] that are provided with respectively between carbon bag [6] and lithium sheet [4] and carbon bag [6] and negative pole bottom [8], it is characterized in that: barrier film [5,7] is 2～5 layers.
2, battery according to claim 1 is characterized in that: barrier film [5,7] is glass fibre or polypropylene mat.
