The utility model relates to a primary battery and a combination thereof, which belongs to the technical field of chemical power source.
[2]
In recent years, electronic products to micromation, intelligent, series development, the original battery has been applied more widely. Many special series of electronic products to primary battery for special accessory requirements, require safe, reliable, long service life, high specific energy, convenient use, temperature adaptation performance, and the like. key encryption start the electronic equipment of the power supply is one of the example, but the vast majority of the original battery can't be given consideration to achieve the above-mentioned requirements.
[3]
The utility model is to meet series key of the electronic product design of the power supply needs.
[4]
The utility model is realized by the following technical measures:
[5]
A battery pack, the two monomer the original battery, characterized in that two of the original battery packaging into a whole, the size the diameter of 34 mm, height of 64 mm, the nominal voltage is 7.2V, and the battery casing is provided with a safety pressure relief device.
[6]
The monomer primary battery is lithium-thionyl chloride (SOCl 2 ) system battery, shape and size the diameter of 33 mm, height 31 mm, the nominal voltage is 3.6 V.
[7]
The battery casing of the safety pressure relief device is a strip-shaped engraving wound trough.
[8]
The glass insulator by the primary battery, the battery cover, lead, the positive electrode assembly (nickel current collection net and is made of carbon black or the like), diaphragm, cathode assembly (metal lithium, is made of such as a current collector), thionyl chloride electrolyte, insulation, housing, safety pressure relief device, a tube, and the like.
[9]
The design of the original battery limits the lithium , the laminated core part of the coil structure. Outer cover and battery cover composed of nickel-plated cold-rolled steel plate coining forming, sealing structure as a whole. To the top end of the metal-glass seal, a filling tube at the bottom of the, anode lead clamp between the housing and the battery cover, is connected with the negative pole lead wire and the middle tantalum column. The bottom of the core body, and the upper part of the inside of the battery cover has a porosity of 90% of the glass fiber membrane. wound trough a strip moment side of the shell as a pressure relief device.
[10]
key series in accordance with the voltage requirements of electronic products, composed of two superposed cells only, in order to lead wire connecting, insulating sheet isolation, a positive pole of the battery only welds positively pole cap, only one of the following welds negative pole cap at the bottom of the battery, the positive electrode of the battery below directs the seam welding on the shell at the bottom of the battery, and by the insulative polyester wrap integrally packaged into heat shrinkable plastic sleeve, battery pack.
[11]
The overall structure and design dimension, Li/SOCl 2 system is of the product compared with products with other electrochemical system, under the same service conditions, high capacity 6-8 times, high voltage 2 times, the discharge voltage is stable; the working temperature within a range of -45-+ 55 the [...] , years of self-discharge rate is lower than 1.5%, the sealing structure, the life time of the battery is ensured up to 10 years. Reasonable the internal structure and the safety pressure relief device for the safety and the reliability of the battery pack.
