Characteristics of lithium-thionyl chloride battery

- Oct 11, 2018 -

The nominal voltage is 3.6V, lithium metal is used as the negative electrode, thionyl chloride is used as the negative electrode, thionyl chloride is used as the positive electrode, and lithium primary battery using inorganic electrolyte is used as the lithium-thionyl chloride battery. Lithium thionyl chloride batteries are the highest specific energy and can currently reach levels of 500 Wh/kg or 1000 Wh/L. It is rated at 3 6V and has an extremely flat 34V discharge characteristic at medium current discharge (flat discharge in a 90% capacity range with little change). The battery can operate from -40 ° C to +85 ° C, but the capacity at -40 ° C is about 50% of the normal temperature capacity. The self-discharge rate is low (year self-discharge rate ≤ 1%) and the storage life is up to 10 years. High and stable operating voltage: The standard voltage is 3.6V and the operating voltage remains significantly smooth throughout its service life. Wide temperature range: can be used between -55 ° C and 85 ° C temperature. High energy density: Lithium thionyl chloride battery has a specific energy of up to 430Wh/kg or 1080Wh/L. Good storage life and reliability: It has a special low self-discharge characteristics, annual self-discharge rate <=1%, and its manufacturing is made of stainless steel shell and metal-glass seal hermetic welded structure, so the shelf life of the battery It was confirmed that it can be stored for more than 10 years at room temperature. Good safety, no pollution: no heavy metals such as mercury, cadmium, lead, etc., no environmental hazards.
