We all know how important it is to have a dependable power source when we are away from civilization. Whether camping, hunting, or working in the yard, a portable power station can be a lifesaver. But what kind of battery should you use to power your mobile power station?

From ternary lithium batteries to lead-acid batteries, there are many options on the market. But for a power station that is truly portable, lightweight, and long-lasting, there is only one option: the lithium iron phosphate (LiFePO4) battery.

Let’s look at how other batteries stack up against the LiFePO4 battery from the perspective of portability, weight, and lifespan.

Ternary Lithium Battery

A ternary lithium battery is a type of lithium-ion battery that uses three different transition metals in the cathode. The most common configuration is cobalt oxide (CoO), nickel oxide (NiO), and manganese oxide (MnO). While this combination of metals makes for a more stable battery, it also makes it heavier and less efficient.

The lifespan of a ternary lithium battery is around 1000 cycles, and deep charging and discharging will shorten that lifespan even further.

Advantages

The advantage of using multiple metals in the cathode is that it allows for a higher voltage and energy density than batteries with only one type of transition metal. A ternary lithium battery can store more energy in a smaller package than other lithium-ion batteries.

Disadvantages

The disadvantages of ternary lithium batteries are their weight and lifespan. Because they use multiple metals in the cathode, they are significantly heavier than other lithium-ion batteries. And their lifespan is shorter because they are not as stable as other lithium-ion batteries.

The cobalt in the cathode is also a significant concern. Cobalt is a rare and expensive metal, so the cost of manufacturing a ternary lithium battery is high. And because cobalt is mined in countries with unstable governments, there is a risk that the supply of cobalt could be disrupted.

Lead-Acid Battery

A lead-acid battery is a type of battery that uses lead and sulfuric acid to create an electrical current. Lead-acid batteries are the oldest type and are still used in some applications today. This type of battery is heavy and inefficient but inexpensive to manufacture.

The lifespan of a lead-acid battery is around 6-8 years, and it is not very environmentally friendly.

Disadvantages

The main disadvantage of lead-acid batteries is their efficiency. They are not very efficient, so they require more power to run than other types of batteries. With 30-40 watt-hours per kilogram (Wh/kg) of energy density, lead-acid batteries are significantly less efficient than different lithium-ion batteries.

Additionally, lead-acid batteries are heavy and bulky, making them difficult to use in portable applications. Lead-acid batteries also have a relatively short lifespan and are not environmentally friendly.

Sodium-Ion Battery

A sodium-ion battery is a type of battery that uses sodium and other materials to create an electrical current. Sodium-ion batteries are a newer technology and are not as widely used as lead-acid batteries.

However, they can potentially be a more environmentally friendly and efficient alternative to lead-acid batteries or other types of batteries. With further development, sodium-ion batteries could become a viable option for portable applications.

Advantages

One of the advantages of sodium-ion batteries is that they are more environmentally friendly than most other types of batteries. Sodium-ion batteries do not contain lead or other toxic materials, making them less environmentally harmful.

Additionally, sodium-ion batteries are more efficient than lead-acid batteries, with an energy density of around 75–165 Wh/kg.

Disadvantages

Although sodium-ion batteries are more efficient than lead-acid batteries, they are not as widely used. This is because sodium-ion batteries are a newer technology and are not as well understood as other types of batteries. Additionally, sodium-ion batteries can be expensive to produce, which limits their commercial viability.

LiFePO4 Battery

A LiFePO4 battery (lithium iron phosphate or LFP) is a type of battery that uses lithium and iron to create an electrical current. LiFePO4 batteries are similar to other lithium-ion batteries but have vital advantages.

LiFePO4 batteries are a newer technology, but they are quickly gaining popularity due to their high energy density and long lifespan. Since LiFePO4 batteries do not contain cobalt or other toxic materials, they are also more environmentally friendly than other batteries. Lithium-iron phosphate batteries are also more stable than other lithium-ion batteries, making them less likely to catch fire or explode.

Advantages

Using a LiFePO4 battery has several advantages over other types of batteries. One of the most significant advantages is that LiFePO4 batteries have a very high energy density. With an energy density of up to 200 Wh/kg, LiFePO4 batteries are more than three times as efficient as lead-acid batteries.

Additionally, LiFePO4 batteries have a very long lifespan. A LiFePO4 battery can last more than 20 years with proper care. From an environmental standpoint, LiFePO4 batteries are also superior to other types of batteries. LiFePO4 batteries do not contain lead or other toxic materials, making them much safer for the environment.

Disadvantages

One of the only disadvantages of using a LiFePO4 battery is its cost. However, the cost of LiFePO4 batteries has been dropping recently, and they are expected to become more affordable. The good news is that their long lifespan and high efficiency offset the high cost of LiFePO4 batteries.
