Blomiky 4 Pack 3.6V 2700mAh ER14505 Lithium AA Size Li-SOCL2 Battery for Smart Electronic Sensor Gas Water Meter 14505 4

This battery can storage 10 years, and 650WH/KG+ hight energy density, so battery can up to 3.6V 2700mAh for each unit. The battery work in temperate range -60? to 85?. Factory get UL TUV certification, and meet UN standard request. Lithium thionyl battery is non-rechargeable lithium metal battery, its electrolyte and positive electrode are all thionyl chloride. When metal lithium have chemical react with thionyl chloride, it will produce lithium chloride oxide, which attached to metal lithium, we called it oxide film(also named passivation film). This passivation film can prevent the reaction going on continuously and quickly. That’s to say, this oxide film have protection function to the negative electrode metal lithium, which is also the reason why the battery have long term static storage feature. After produced Lithium chloride protection film, the stop of internal reaction is relatively not absolutely, no matter spiral type battery suitable to high current discharge or bobbin type battery for small current discharge. As long as the battery stand still, internal extreme slow reaction will make the passivation film thicken. The appearance of passivation film makes the internal resistance of lithium thionyl keep changing continuously. It’s also just the generation of passivation film makes the year self-discharge of lithium thionyl battery very small in normal temperature. (bobbin type lower than 1%, spiral type lower than 2%) . What’s more, the energy density of lithium thionyl battery can high to be 700wh/kg, which makes it to be absolute star product of IOT presently with low power consumption and long life features. The passivation of lithium thionyl battery cannot be totally resolved by internal formula at present. But in practical application, there are some ways to eliminate the passivation, taking ER14505M for example, if start to use after half an year storage, it can use 15? resistance discharging 10-20 minutes to active. If other models stored a long time before usage, please consult xx for the according safety resistance to eliminate the passivation. To avoid the passivation influence terminal electrical equipment after battery inserted, xx recommend below two solutions of circuit. A.Add a pulse discharge when eliminate passivation by active circuit, by using proper current to compact the battery, the current and frequency of pulse discharging decided by the equipment working requirement of highest current and lowest working voltage. a.
