Abstract
The invention relates to a lithium battery which belongs to the technical field of a primary lithium battery, and is mainly used for solving the problem that the battery capacity is greatly reduced and the short circuit happens due to the displacement of a positive electrode along the axial direction when the existing lithium battery is subjected to the axial impact or severe movement. The lithium battery is mainly characterized by comprising a battery shell, a positive column, a cover plate, a piece of seal insulation glass, lithium metal, a diaphragm, a positive electrode, electrolyte and a seal steel ball, wherein the positive electrode is of a cylindrical carbon-coating structure, the seal insulation glass is connected between the cover plate and the positive column, and the seal steel ball is arranged at the center of the bottom of the battery shell; the upper plane of the positive electrode is provided with a positive positioning sheet which is fixed on the positive column. The lithium battery has characteristics that the axial movement of the positive electrode when the battery is subjected to the axial impact or severe movement can be effectively prevented and can be mainly used for the primary lithium batteries such as a lithium-thionyl chloride battery, a lithium-sulfur dioxide battery and a lithium-manganese dioxide battery.
Description
Technical field
The invention belongs to lithium primary cell technical field.Be specifically related to a kind of structure of lithium battery.
Background technology
Carbon packet mode lithium-thionyl chloride primary cell is by battery case, cover plate, the lithium anode being attached to internal surface of battery shell, positive pole (cylindrical carbon bag, make for main with acetylene black and PTFE), wrap up fibreglass diaphragm that whole positive pole makes itself and cathode of lithium separate and electrolyte (with thionyl chloride with tetrachloro-lithium aluminate for main preparation face becomes) and form, the structure of cylindrical carbon packet mode is the electric current in order to limit battery, ensure the fail safe of battery, the capacity relative of this battery is higher.This anode structure is very high to the requirement of producing, in manufacturing process, the more abnormal capacity of battery that will cause produces larger fluctuation, and anode does not have powerful fixation, if battery axial direction impacts or strenuous exercise, positive pole can produce displacement vertically, thus causes battery capacity greatly to decline even producing short circuit.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, provide a kind of positive pole that can effectively prevent at the lithium battery of battery by movement vertically when axial direction impact or strenuous exercise.
Technical solution of the present invention is: a kind of lithium battery, comprise battery case, positive terminal, cover plate, sealed insulation glass, lithium metal, barrier film, positive pole, electrolyte, sealing steel ball, just very cylindrical carbon wrap type structure, sealed insulation glass is connected between cover plate and positive terminal, sealing steel ball is positioned at battery case bottom centre, it is characterized in that: on described positive pole, plane place is provided with the positive pole spacer be fixed on positive terminal.
Positive pole spacer described in technical solution of the present invention is by the one section of sleeve be sleeved on positive terminal and be fixed on this sleeve ends and the plane shuttering panels vertical with sleeve is formed.
Positive pole spacer described in technical solution of the present invention is the positive pole spacer of metal material, is welded on positive terminal.
Positive pole spacer described in technical solution of the present invention is the positive pole spacer of telfon plastic or mica material, is fitted on positive terminal.
The area of the plane shuttering panels described in technical solution of the present invention is less than the side end face area of positive pole.
Plane shuttering panels described in technical solution of the present invention is the annular plane baffle plate that diameter is less than positive polar diameter.
Plane shuttering panels described in technical solution of the present invention is that circumferential periphery is along being corrugated annular plane baffle plate.
The present invention is due on the basis of the existing lithium battery be made up of battery case, positive terminal, cover plate, sealed insulation glass, lithium metal, barrier film, positive pole, electrolyte, sealing steel ball, on positive pole, plane place adds a positive pole spacer be fixed on positive terminal, thus positive pole is made can to move in no instance, thus ensure that battery is when severe impact or motion, all there will not be the situation of capacity decline or short circuit.Through experimental verification, the consistency of battery capacity is greatly improved, and solves people and wants for a long time to solve and open question.Instant invention overcomes the deficiencies in the prior art, have and can effectively prevent positive pole in the feature of battery by movement vertically when axial direction impact or strenuous exercise, be mainly used in the lithium primary cells such as lithium thionyl battery, lithium sulfur dioxide cell and lithium manganese dioxide cell.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1.Lithium battery of the present invention is made up of battery case 1, positive terminal 2, cover plate 3, sealed insulation glass 4, lithium metal 5, barrier film 6, positive pole 7, electrolyte 8, sealing steel ball 9 and positive pole spacer 10, wherein, except positive pole spacer 10, is prior art.Battery case 1 and cover plate 3 can be stainless steel or mild steel.Positive terminal 2 can be stainless steel or steel alloy (as 4J28,4J29,4J50 etc.).Sealed insulation glass 4 is connected between cover plate 3 and positive terminal 2, and being the glass that matches with cover plate 3 and positive terminal 2 thermal coefficient of expansion is bonded together through high temperature sintering and cover plate 3 and positive terminal 2, is formed and seals and insulate.Lithium metal 5 on battery case 1 inwall, becomes galvanic anode active material with metal lithium bands roll extrusion.Barrier film 6 makes a basic sealed cylindrical by glass fibre, for cell cathode and positive level are separated.Positive pole 7 is cylindrical carbon wrap type structure, is that main component is made by acetylene black and PTFE.The main component of electrolyte 8 is thionyl chloride and tetrachloro-lithium aluminate, injects battery by the liquid injection hole of battery case 1 bottom centre, and sealing steel ball 9 is stainless steels.Positive pole spacer 10 is fixed on the positive terminal 2 at plane place on positive pole 7.Positive pole spacer 10 is by the one section of sleeve be sleeved on positive terminal 2 and be fixed on this sleeve ends and the plane shuttering panels vertical with sleeve is formed.Positive pole spacer 10 is the positive pole spacer of metal material, as nickel, stainless steel etc., is welded on positive terminal 2.Plane shuttering panels is the annular plane baffle plate that diameter is less than positive pole 7 diameter, and the area of plane shuttering panels is less than the side end face area of positive pole 7, can not have influence on the effect of electrolyte 8 like this.Plane shuttering panels also can be circumferential periphery edge is corrugated annular plane baffle plate, is equally also the effect that can not have influence on electrolyte 8.The above-mentioned positive pole spacer be made up of sleeve and plane shuttering panels can also be the nonmetal positive pole spacer as the material such as telfon plastic, mica, and available mechanical mode compresses and is installed on positive terminal 2.
