Molten Salt Battery: Introduction, Working And Making

Molten Salt Battery: Introduction, Working And Making

Page view

The advance of technology allows researchers to develop many things, and the battery is one of those things. From nickel batteries to lithium-ion batteries, they are invented fr the purpose of better energy and usage by people. Now, molten salt battery has entered the competition. In this article, we will talk about molten salt battery and every aspect of it. We will give the introduction, how it’s working, and how to make a molten salt battery.

What is molten salt battery made of?

What makes molten salt battery different is its content. Unlike other batteries, molten salt battery uses, of course, molten salt as their electrolytes. Molten salt is perfect as electrolytes because they are solid at room temperature, making it passable to be stored at room temperature when the battery is not used.

Another thing that should be note is its density and power. Molten salt batteries are known for their high density and power, making it one of the feasible batteries that can be used until now.

There are different types of molten salt batterie. They are:

Thermal Battery

They are molten salt batteries that cannot be charged. They are used for the purpose of giving a large amount of power at a certain amount of time, usually in seconds. Thermal molten salt batteries are mostly used for objects such as missiles and rockets due to the large amount og energy it delivers.

Liquid Metal Battery

The latest molten salt battery invented by Donal Sadoway. What makes Sadoway’s battery unique is its simple and yet effective and inexpensive design. Due to its inexpensive and yet effective design, Sadoway’s molten salt battery is perfect for large objects such as grid applications. Using liquid metal battery by Sadoway can save lots of expense, hence it’s usage on big-scale objects or projects.

Sodium-Sulfur Battery

Sodium-sulfur battery is another molten salt battery that is also inexpensive in terms of materials. Just like liquid molten salt battery, the sodium-sulfur battery is also used for grid applications. What makes them different are their materials, chemicals, and functional temperature. Sodium-sulfur battery functions around 300 to 350 degree celsius, while liquid metal battery is around 450 degree celsius (thanks to the new design that includes new electrodes that allow higher temperature).

Sodium-Nickel Chloride Battery

Although the main core of the battery uses molten sodium, there are several parts of this battery that uses nickel. To be specific, for the positive electrodes. Moreover, they also used nickel chloride in the charged state (only nicked is used during discharged). The battery usually operates at 270 to 350 degree celsius, but the latest discovery made the battery possible to be used at 90 degree celsius.

People keep researching the advancement of the molten salt battery not without reason. It has many benefits that make it superior to other batteries, such as:

●Longer lifespan due to the nature of the liquid electrode.

●More efficient in terms of energy due to the lack of separator.

●Higher density for the current due to its liquid nature.

●Simple process of creation due to its simple component.

●Inexpensive despite a large amount of energy it delivers.

●Can be made by self at a short amount of time.

With such benefits, no wonder molten salt battery is winning right now!

How does a molten salt battery work?

The way molten salt battery works is pretty simple. Molten salt battery works by having a positive electrode (Usually antimony) and a negative magnesium electrode separated by a thin layer of a paper that has been soaked in a formula. The formula can be the combination of several things such as potassium chloride and lithium chloride (the mixture that will be used in this article).

What makes them unique is the liquid electrodes, which is continuously expanding and contracting. The expansion and the contraction allow the electrodes to be regenerated every time there is a charge and discharge cycle, which is an efficient move that helps to increase the lifespan of the battery.

How do you make a molten salt battery?

Making a molten salt battery is not a hard task. However, it should not be done carelessly, so you need to take precautions. Make sure you’re doing everything on a clean flat surface to get the best of the battery.

The ingredients you need for molten salt battery are:

● Salt, to be specific KCI and LCi salt for making the electrocyte

●Magnesium and nickel for electrodes

●Fiberglass cloth

●Device to measure volt

Once you have them, it’s time to start making the battery! Below are the steps to make the battery:

1.Heat up magnesium,

2.Gives a little bit of heat on nickel.

3.Find the temperature that will melt both potassium chloride and lithium chloride.

4.Weight out the potassium and lithium chloride, then mix them.

5.Gives heat to the mixture and slowly melt them out.

6.Test the voltage by putting the positive and negative hand into the mixture.

7.Put the magnesium and nickel on each side of the string.

8.Dip the fiberglass cloth into the mixture of magnesium and nickel. Make sure you straighten the fiberglass cloth since the mixture can turn into solid easily.

9.Stack the nickel, fiberglass cloth, and magnesium. You can press on it using the cup that contains the liquid mixture.

10.Test out the voltage again to check the amount of voltage you get.

11.Connect the wires to the device you want to light up, such as small light or white LED.

And you’re done! Making a molten salt battery is not that hard, isn’t it?

Making a molten salt battery is not hard to do, although it requires the most meticulous observation and process. It is not complicated, but you still need to do the steps carefully to create the perfect molten salt battery. However, once you’ve understood the basics, you will be able to gain access to one of the most easily-created batteries that provide high energy for your device. So what are you waiting for? Let’s buy the materials and create a molten salt battery as soon as possible!
