Lithium-Thionyl Chloride Batteries Li-SOCL2

When looking for a battery for your specific application, you will often come across the option of a lithium-thionyl chloride battery, or a Li-SOCl2 battery. This battery has several advantages over other types of batteries, making it a good choice for many applications.

How Does It Work?

A lithium-thionyl chloride battery works by using a thin layer of lithium metal that is deposited onto a carbon electrode. This thin layer of lithium is what provides the battery with its high energy density. The other half of the cell contains a thionyl chloride electrolyte, which helps to facilitate the flow of electrons between the electrodes.

It is this simple chemical reaction that allows the battery to produce a high amount of power for its size. A lithium-thionyl chloride battery can produce up to three times more power than a similarly sized lead-acid battery. When the battery is being used, the lithium metal reacts with the thionyl chloride electrolyte to produce electrical energy.

Li-SOCL2 Battery Features

1. Wide Temperature Range

One of the big advantages that a lithium-thionyl chloride battery has to offer is its wide temperature range. This type of battery can be used in temperatures ranging from -60°C to +85°C. This makes it a good choice for applications that are located in extreme climates.

2. Low Self-Discharge Rate

Another advantage of this battery is its low self-discharge rate. When compared to other types of batteries, a lithium-thionyl chloride battery will hold its charge for a much longer period. This is because the chemical reaction that takes place within the battery is much slower than in other types of batteries.

3. High Energy Density

As we mentioned before, one of the main advantages of a lithium-thionyl chloride battery is its high energy density. This type of battery can store up to three times more energy than a lead-acid battery of the same size. This is because the lithium metal used in this type of battery has a higher energy density than lead.

4. Low Maintenance

Another benefit of using a lithium-thionyl chloride battery is the fact that it requires very little maintenance. Unlike other types of batteries, this battery does not require regular watering or charging. This makes it a good choice for applications where maintenance is difficult or impossible.
