Lithium-thionyl-chloride (LiSOCl2) is a type of battery chemistry that was first developed in the early 1970s. It was initially used in military applications, such as powering torpedoes and missiles, due to its high energy density and long shelf life. In the 1980s, LiSOCl2 batteries began to be used in consumer electronics, such as calculators and watches.
Typical Use #
LiSOCl2 batteries are commonly used in applications that require a long shelf life, such as medical devices, emergency lighting, and remote monitoring systems. They are also used in applications that require a high energy density, such as electric vehicles, portable electronics, and military applications. LiSOCl2 batteries are also used in applications that require a wide temperature range, such as in space exploration and deep-sea exploration.
LiSOCl2 batteries are composed of a lithium anode, a thionyl chloride cathode, and an electrolyte. The anode is typically made of lithium metal, while the cathode is typically made of thionyl chloride. The electrolyte is typically a mixture of lithium chloride and thionyl chloride. The battery design is sealed, which helps to prevent leakage and corrosion.
LiSOCl2 batteries are typically designed with a voltage of 3.6V and a capacity of up to 10Ah. They are also designed with a high energy density, typically ranging from 500-1000Wh/kg. LiSOCl2 batteries are also designed with a long shelf life, typically ranging from 10-20 years.
LiSOCl2 batteries are typically designed with a high self-discharge rate, typically ranging from 1-2% per month. This high self-discharge rate is due to the high reactivity of the lithium metal anode. LiSOCl2 batteries are also designed with a high internal resistance, typically ranging from 0.1-0.5 ohms. This high internal resistance can limit the amount of current that can be drawn from the battery.
LiSOCl2 batteries are typically designed with a wide temperature range, typically ranging from -40°C to +85°C. This wide temperature range makes them suitable for use in a variety of applications. LiSOCl2 batteries are also designed with a high cycle life, typically ranging from 500-1000 cycles. This high cycle life makes them suitable for use in applications that require frequent cycling.
