What is a semi-solid battery? Also, how does it compare to lithium iron phosphate batteries?

Today, batteries are essential in our lives and come in many types. It's important to choose wisely, especially for large batteries in portable power stations and electric vehicles. So, how do you pick the right battery? What are the features, benefits, and drawbacks of each type?

In this article, we'll clearly explain the differences between semi-solid-state batteries, lithium iron phosphate batteries (LiFePO4), and ternary lithium-ion batteries. This will help you find the best battery for your needs.

What is a Semi-Solid State Battery?

A semi-solid-state battery blends solid and liquid electrolytes. Mainly, it was designed for lithium-ion batteries. Notably, it features high ion conductivity. These batteries are seen as promising. They offer high energy density, safety, longevity, and low environmental impact.

Semi-solid-state batteries are available in three forms: gel-polymer, clay-like and with liquid additive.

● Gel-polymer type: These flexible batteries have electrolytes in gel form. They are resistant to bending and can be charged quickly, making them ideal for card-type and portable devices.

● Clay-like type: These batteries have clay-like consistency, with the electrolyte integrated into the electrodes. They pose a low risk of leakage or ignition and are long-lasting, making them suitable for solar power generation and automotive applications.

● Liquid-immersed type: These are ceramic batteries impregnated with a small amount of electrolyte. They have high thermal stability and can operate at high temperatures, making them perfect for IoT devices, industrial equipment and car interiors.

What is a Lithium Iron Phosphate (LiFePO4) Battery?

A lithium iron phosphate battery (LiFePO4) is a type of lithium-ion battery that uses lithium iron phosphate as the cathode material.

Lithium iron phosphate is an affordable and stable material known for its low risk of thermal runaway and ignition. Lithium iron phosphate batteries have a long life and are favored for their high number of charge and discharge cycles. Since lithium iron phosphate is not a rare metal, it is also considered less harmful to the environment.

What is a Ternary Lithium-Ion Battery?

A ternary lithium-ion battery is a type of lithium-ion battery that uses a ternary compound, such as nickel-cobalt-manganese (NCM) or nickel-cobalt-aluminum (NCA), as the cathode material.

Ternary systems are known for their high energy density and stable performance even at low temperatures. However, the inclusion of the rare metal cobalt makes them more expensive and carries a higher risk of thermal runaway and ignition.

Advantages and Disadvantages

Below you will find a summary of the advantages and disadvantages of semi-solid-state batteries, lithium iron phosphate batteries (LiFePO4) and ternary lithium-ion batteries.

Conclusion

Now that you have a basic understanding of the characteristics, advantages, and disadvantages of semi-solid-state batteries, lithium iron phosphate (LiFePO4) batteries, and ternary lithium-ion batteries, it is clear that semi-solid-state batteries stand out in terms of safety, cycle life, portability, and performance.
