Abstract
The utility model provides a cylindrical primary lithium battery, relates to a battery structure, and in particular relates to a structure of a primary lithium battery. The cylindrical primary lithium battery comprises a positive pole terminal (8), a cover group (9), a sealing steel ball (10), a glass seal (11), an insulation gasket (12) and a PTEE gasket (5) which are arranged at the upper end of a shell (1), wherein the shell (1) is provided with simple substance lithium (2), a diaphragm (3) and a positive electrode (6) from outside to inside, a positive electrode current collecting net (4) is arranged between the diaphragm (3) and the positive electrode (6), a metal strip (7) is arranged at the upper end of the positive electrode current collecting net (4) to be connected with the positive pole terminal (8), the top of the positive electrode (6) is low in the middle and high in the periphery, and the positive electrode current collecting net (4) is made of a metal material. The cylindrical primary lithium battery has the beneficial effects that the contact area between a positive electrode current collecting body and a positive electrode part is increased, the internal resistance of the battery is reduced, the discharge capacity and large-current discharge capacity of the battery are increased, a nickel net or a stainless steel wire net as the stainless steel wire adopts a un-closed or closed form, and the structure is simple.
Description
Technical field
The utility model relates to battery structure, especially the disposable lithium-battery structure.
Background technology
At present, the known cylindrical disposable lithium-battery that forms as negative pole as anodal carrier and lithium simple substance as positive pole or particle with particle, the battery plus plate current-collecting body of this structure and anodal contact area are too little, and internal resistance is very large, and discharge capacity is low and limited heavy-current discharge.
Summary of the invention
The purpose of this utility model is to provide a kind of discharge capacity of battery and cylindrical disposable lithium-battery of large current discharging capability of improving.
It comprises the positive terminal (8) of shell (1) upper end setting, lid group (9), sealing steel ball (10), glass envelope (11), insulation spacer (12), polytetrafluoro pad (5); Shell (1) is from simple substance lithium (2) being set outside to inside, barrier film (3) and anodal (6); Between barrier film (3) and anodal (6), anode collection net (4) is set.
The upper end of anode collection net (4) arranges bonding jumper (7) and connects positive terminal (8).。
The top of anodal (6), middle low, surrounding is high.
Anode collection net (4) is that metal material is made.
The beneficial effects of the utility model are, can increase plus plate current-collecting body and anodal contact area partly, when reducing the internal resistance of cell, improve discharge capacity and the large current discharging capability of battery, nickel screen or stainless (steel) wire employing as plus plate current-collecting body are not sealed or closing form, and be simple in structure.

Accompanying drawing 1 is main pseudosection of the present utility model;
Accompanying drawing 2 is stereograms of the utility model anode collection net;
Accompanying drawing 3 is main view plane expanded views of the utility model anode collection net;
Accompanying drawing 4 is that the utility model battery and conventional capacity type battery are that the 200mA cut-ff voltage is the discharge curve comparison diagram of 2V at the lower discharging current of low temperature (30 ℃);
Accompanying drawing 5 is that utility model battery and conventional capacity type battery are that the 60mA cut-ff voltage is the discharge curve comparison diagram of 2V at the lower discharging current of normal temperature (25 ℃);
Embodiment:
The positive terminal (8) that shell (1) upper end arranges, lid group (9), sealing steel ball (10), glass envelope (11), insulation spacer (12), polytetrafluoro pad (5); Shell (1) is from simple substance lithium (2) being set outside to inside, barrier film (3) and anodal (6); Between barrier film (3) and anodal (6), anode collection net (4) is set.The upper end of anode collection net (4) arranges bonding jumper (7) and connects positive terminal (8).The crown center of anodal (6) is low, and surrounding is high.Anode collection net (4) is that metal material is made.As stainless steel, nickel etc.
Bonding jumper (7) between anode collection net (4) and pole (8) can be integrally welded with nickel bar or stainless steel strip.The height of barrier film (3) will prevent that with anode collection net (4) both positive and negative polarity from contacting and short circuit higher than simple substance lithium (2).Anode collection net (4) can add in the mode that rectangle (Fig. 3) is reeled, and also can add with cylinder web form (Fig. 2).The crown center of anodal (6) is low, and surrounding is high, can increase the contact area of both positive and negative polarity when satisfying storage electrolyte.Add anode collection net (4) can increase collector and anodal contact area partly, can reduce the internal resistance of battery, improve discharge capacity and improve discharge capability under large electric current.
Fig. 4-Fig. 7 is the utility model and conventional capacity type battery discharge curve comparison figure; In figure, 1 is: the utility model battery discharge curve, 2 is conventional capacity type battery discharge curve.
