Abstract
The utility model relates to a 9V lithium thionyl chloride battery with improved voltage lagging components, which is characterized in that: positive and negative electrodes of the battery are connected by a resistance; the value of the connecting resistance between the positive and negative electrodes of the battery is between 1 MQ and 8 MQ; the resistance is placed in a plastic part with a metal electrode cap, and covered at the two ends of the electrode cap of the battery. The utility model has the characteristics that: The lag characteristic of the battery is eliminated by connecting proper resistance to the positive and negative electrodes of the battery, and the lag of the battery is eliminated by large resistance and small current discharge; the battery capacity loss per year is within 3 percents to 7 percents, and the device is simple without affecting the normal use of the batteries, packaging, and electric performance and other requirements. The utility model has the advantages of easy implementation, simple structure, obvious effect, low price and small loss of electric quantity, and can ensure the normal service life of the battery.
Description
Technical field
The utility model relates to electronics and electrochemical field, especially a kind of can be effectively and improve simply that the load voltage hysteresis appears in the lithium thionyl chloride cell long-term storage and band improves the 9V lithium thionyl chloride cell of voltage delay parts.
Background technology
Lithium thionyl chloride cell is the highest a kind of battery of specific energy in the present practical application battery in the world.It is exactly can form the passivating film of one deck densification at electrode surface in storage process that lithium thionyl chloride cell has a characteristic, thereby stops reaction to be proceeded.In discharge process, this tunic can be punctured by electric current. and along with the storage time is more and more longer, this layer passivating film can be more and more thicker, when the needs battery provides electric current, load voltage can drop to very low in moment, cause the battery can't operate as normal, and this phenomenon is referred to as voltage delay.Improve the important topic of lithium thionyl chloride cell hysteresis also becoming battery research.
The engineers of field of batteries has adopted a lot of ways of improving voltage delay for this reason, has also obtained some achievements, but some produces effects not quite, and then cost is too high for some, can't implement.We find that battery can suppress the passivating film formation speed in being in the Weak current discharge process, based on this: we have proposed following can effectively improve the technical scheme that load voltage hysteresis problem appears in the lithium thionyl chloride cell long-term storage.
Summary of the invention
Disclosed technical scheme is a kind of with the 9V lithium thionyl chloride cell that improves the voltage delay parts, and the purpose of this scheme is to improve the problem that the load voltage hysteresis appears in the lithium thionyl chloride cell long-term storage simply, effectively, inexpensively.
Described band improves it is characterized in that of 9V lithium thionyl chloride cell of voltage delay parts: be connected with resistance between described battery plus-negative plate, this resistance places on the protective device of a band metal polar cap, covers the electrode cap two ends of battery.Connect the resistance of resistance between battery plus-negative plate between 1M Ω～8M Ω.
Characteristics of the present utility model are: eliminate the battery hysteresis characteristic in the mode that connects proper resistor between battery plus-negative plate, eliminating battery with the method for big resistance low discharging current lags behind, year battery capacity is lost in the 3%-7%, and device does not simply influence requirements such as the normal use, packing, electrical property of battery.The utility model has the advantages that: implement convenient, simple in structure, effect is remarkable, cheap, electric quantity loss is little, can guarantee battery normal useful life.

Among the figure: 1--9V lithium thionyl chloride cell, 2-anode, 3--battery cathode, 4-protective device, 5-resistance, 6--metal polar cap.
Embodiment.
Fig. 2-1, Fig. 2-2 illustrated that this resistance is to place in the working of plastics protective device 4 of a band metal polar cap 6, and Fig. 3 and Fig. 1-2 represent that protective device 4 covers the anode 2 and battery cathode 3 electrode cap two ends of battery 1.
Resistance places in the working of plastics of a simple band metal polar cap, directly working of plastics protective device 4 is covered the electrode cap two ends of battery before dispatching from the factory, and directly working of plastics is taken off before the use and can normally use.Operation principle of the present utility model is: battery can suppress the passivating film formation speed in being in the Weak current discharge process; on this basis; we adopt and insert little load between battery the two poles of the earth; make lithium thionyl chloride cell ER9V in storage process, keep Weak current to hinder the generation and the growth of passivating film; can effectively improve lithium thionyl chloride cell ER9V long-term storage and the load voltage hysteresis occur; make battery can keep normal use after taking off protective device 4, protective device 4 is plastic fasteners of a kind of built-in resistor.
Battery dispatch from the factory before with parts left-hand thread shown in Fig. 2-1, Fig. 2-2 on battery 1, show as Fig. 3.Removing protective device 4 before the use can normally use.
