What is the difference between a liquid battery and a lithium polymer battery?

The main difference between a liquid battery and a lithium polymer battery is the difference in electrolytes used in their manufacturing. A liquid battery has a liquid electrolyte. One the other hand, a lithium polymer battery comes from a dry solid electrolyte. So, this is a major manufacturing difference between these batteries; therefore, they both have amazing features. 

Which option is better if you are considering buying between a liquid battery and a lithium polymer battery? You would certainly want to buy a safer, more durable, and long-lasting battery. In this debate, a lithium polymer battery is a safer option as compared to a liquid battery.

The solid gel-like electrolyte is safer than the liquid electrolyte

You might wonder why a lithium polymer battery is safer than a liquid battery. Basically, the liquid electrolyte doesn’t have much stability, so it can move from cathode to anode and then back to cathode.

The battery will have more stability when it comes to a solid gel-like electrolyte. The thermal runaway would be none in a lithium polymer battery when the battery is under any impact or in situations of extreme temperatures. The reason is the physical barrier layer that the solid electrolyte creates between the positive and negative electrodes.

If there is a barrier between the positive and negative charges, it is obvious that the battery would perform battery. The ions between the negative and positive charges won’t collide much, and the chances of the battery getting heated up are also minimal. 

If you want to consider a safer battery option, a lithium polymer battery is the best so far because it would be safe for the device to which you will connect it. Plus, you must remember your safety while deciding on the battery. 

Raw Material 

You would certainly want to know about the raw material used in manufacturing both liquid and lithium polymer batteries. As we have discussed, liquid batteries consist of liquid electrolytes that would move from the cathode to the anode and back to the cathode. In lithium polymer batteries, you would find a solid polymer.

The Raw Material of the Liquid Battery

The raw material of a liquid battery would be lithium, cobalt, manganese, and graphite. As we all know, a battery consists of a positive charge, a negative charge, and a separator. It also consists of a liquid electrolyte. The electrolyte material would be an organic solvent, for example, ethylene carbonate. The liquid electrolyte consists of solvent molecules and salt anions that would keep the ionic charge organized to form solvation shells. 

The Raw Material of Lithium Polymer Battery

The construction of liquid batteries and lithium polymer batteries is not much different. You will also find lithium, manganese, cobalt, and graphite in a lithium polymer battery. Basically, you will have to decide which type of battery you want to buy from all the options. When it comes to the electrolyte of a lithium polymer battery, it consists of a solid electrolyte. Yes, a polymer electrolyte would transport ions from the positive anode to the negative cathode but with more stability. 

Electrolyte Form

Every type of battery consists of an electrolyte that takes ions from the positive to the negative charge, so the battery gets recharged. The only difference you would find between a liquid battery and a lithium polymer battery would be the difference in the type of electrolyte only. Following are the two types of electrolytes that you would find in the batteries:

Liquid Electrolyte Form

A liquid electrolyte is a solution of salts like LiPF6 in an organic solvent like ethylene carbonate. The electrolyte in the battery transports the ions from the anode to the cathode and vice versa to generate energy and recharge the battery. In a liquid battery, you will find liquid electrolytes.

Solid Electrolyte Form

A lithium polymer battery consists of a solid electrolyte, which is rechargeable and consists of lithium-ion technology. The solid electrolyte would be a polymer that transports ions from anode to cathode and vice versa. The polymer electrolyte would be a solid gel-type material.

Design of a Liquid Battery and a Lithium Polymer Battery

As we have discussed, the main difference between a liquid and a lithium polymer battery is. The only difference is the different types of electrolytes in both types of batteries. What about the rest of the design? A liquid battery consists of 4 basic components. Anode, cathode, electrolyte, and separator. All these are very basic components that you would find in all the batteries, and every single component plays a significant role. 

If we talk about a liquid battery, the separator is one of the most important components to keep stability between the moving ions so the battery doesn’t heat up and explode eventually. On the other hand, a lithium polymer battery also consists of these four basic components. Still, because of the solid electrolyte, the separator doesn’t have to main much distance between both positive and negative charges. 

Li-polymer batteries are more popular.

You must know that lithium polymer batteries are more popular because you can have them customized according to your requirements. Yes, you can design it in a very small size, and it would be flat and lightweight. These batteries can fit into smaller spaces and any type of shape. Lithium polymer batteries are a durable and long-lasting option because they have more resistance against external factors.

The casing of a lithium polymer battery would be made up of laminated aluminum foil. It means the internal components get more safety from the external factors that might have done damage to them. Because of the aluminum foil casing factor, you can design the final product into almost any type of shape.

Final Words:

You might have understood the difference between liquid and lithium polymer batteries. The manufacturing components are the same, but the only difference is the type of electrolyte that you would find in these batteries. The presence of a liquid electrolyte in a liquid battery and the presence of a solid polymer electrolyte in a lithium polymer battery is the only differentiating factor.
