Description
Technical Field

Background
The passivation of the lithium/thionyl chloride battery is that after the lithium battery is stored for a long time, the negative metal Li of the battery reacts with the positive active material thionyl chloride, a thin passivation film composed of compact crystals is formed on the surface of the negative lithium, the main component of the passivation film is LiCl, and the passivation film effectively prevents the further chemical reaction of the electrolyte thionyl chloride and the lithium metal, so that the lithium thionyl chloride battery has good storage performance. However, the passivation film also limits the lithium ions from flowing to the electrolyte from the metal surface, so that the initial value of the internal resistance of the battery is high, and the initial load voltage is low.
