LiFePo4 Batteries – The Secret and Low-Cost of BLUETTI’s Long-Lasting.
BLUETTI’s Solar Generators with LiFePO4 Battery Cells How to End Competition 4-7x times the Price
It debuted with the EB150 and EB240 Solar Generators, with Bluetti’s first products reopening in 2019. Approximately one year later, they released their flagship model AC200 as a crowdfunding campaign at Indiegogo (powered by NCA cells).
The project has raised nearly $ 7 million in two months.
Since then, Bluetti has been at the forefront of technological innovation and has equipped all their new products with LFP technology on NCM, NCA and lithium-ion battery chemistry. You may ask why they did this.Well, in this article, we aim to provide an explanation for their reasoning as satisfactorily as we can.
What are LiFePO4 batteries?
LFP or LiFePO4 is a lithium iron phosphate and was discovered back in 1996.
For all the science geeks out there, its anode material is LiaC6 and the cathode object is LibFePO4, the conductor is Li +.
LFP batteries provide some of the best electrochemical performance with the addition of low resistance in the market.
This is made feasible with the aid of using the nano-scale phosphate cathode cloth located withinside the battery.
This lets in the subsequent benefits:
Long lifestyles cycle
Thermal stability
Higher cutting-edge rating
An greater layer of security
How Do LiFePO4 Batteries Work?
The LFP battery is basically made up of the following components:
Positive electrode (cathode), Negative electrode (anode), Electrolyte, Separator, Lithium metal oxide (LiFePO4),cGraphite, Lithium salt.
Polymer membrane charging
Is being charged
When the LiFePO4 battery is charged, the lithium ions are released from the cathode and moved to the anode. They do this by electrolyte.
Being discharged
When an electric load is applied to the battery, the opposite reaction takes place. Lithium ions circulate from anode to cathode.
This movement of lithium ions creates an electron flow between these two electrodes, which produces an electric charge.
NCF & Lithium-ion batteries against LiFePO4 batteries
For this section, we thought it would be best to create a comparison table of Bluetti, Jackery and Ecoflow.
Uses Bluetti LiFePO4, Zachary Lithium-Ion, and Ecoflow NCM.
Manufacturers Battery Chemistry Capacity Life Cycles Cost
Bluetti LiFePO4 2,000 Wh 3,500 $ 1,799
Zachary Lithium-Ion 1,534 Wh 500 $ 1,599
Ecoflow NCM 2,016 Wh 800 $ 1,899
(For reader information, we couldn’t find a capacity size comparable to Jackery’s, so we added their largest capacity generator, which is 1,534 Wh.)
Next, what we want to do is to calculate LCOS or Levelized Cost of Storage in USD / Wh.
When it comes to energy storage, the actual purchase price of a solar generator is simply not dependent (up-front cost).
We need to take into account the total energy in Watt-hours that the Solar Generator can collect and discharge over its lifetime (charge / discharge cycle).
The formula for working with LCOS is as follows:
LCOS = upfront cost / (total kWh capacity x (DoD%) x cycle life)
Let LCOS work for every solar generator manufacturer and their product models.
Bluetti
2 kWh x 0.nine x 3500 = 6300,
$ 1,799 / 6300 = $ 0,285 per kWh
Zachary
1.five kWh x 0.eight x 500 = 600,
$ 1,599 / 600 = $ 2.67 per kWh
Environmental flow
2 kWh x 0.eight x 800 = 1280,
$ 1,899 / 1280 = $ 1.48 per kWh
As we can see when working with LCOS, Bluetti is a much cheaper option in the long run, and LiFePO4 technology lasts longer than both Lithium-ion and NCM.
Keep in mind that the above LCOS includes other components such as charge controller and inverter, as these two components are included in the pre-purchase price.
Why LiFePO4 batteries are a perfect fit for solar generators
To highlight this section, we thought it best to highlight all the advantages that LFP batteries have and why they are suitable for solar generators.
Lightweight
LiFePO4 batteries are lightweight compared to other battery technologies. This is especially important when their application is found in a solar generator. The less heavy the generator is, the more mobile it is. For example, Bluetti’s new AC200 MAX weighs just 61.9lbs (28.1kg).
Although this may not seem like a lot at first glance, you have to remember how much energy storage this machine has gained. For all that energy density, 61 pounds is nothing.
Longevity – Time scale
Perhaps one of the great benefits of an LFP battery is its ability to charge and discharge thousands of times.
In the case of Bluetti, their latest solar generators can be discharged 3500 times.
This is a significant decision-making factor for consumers who want to invest in high-quality products that will last for many years to come. LiFePO4 technology allows this.
High efficiency
Unlike lead-acid batteries, LFP batteries are incredibly efficient. You can use up to 90% of their capacity, which means you can get the most out of your solar generator using as little space as possible.
Generally, LiFePO4 batteries may be discharged past 90% in their capacity.
Don’t needed active management
LFP batteries require no maintenance. This means you don’t have to do anything to extend its life span. You can simply charge and discharge to suit you.
Safety
LiFePO4 batteries are actually safer than NCM batteries. In fact, they are the safest lithium-ion batteries on the market.
These batteries are enclosed in an airtight aluminium case, specifically designed to withstand temperature, pressure differences, punctures and effects.
Extreme temperatures
Bluetti solar generators are capable of operating at a wide range of temperatures, meaning they can be used for a variety of applications.
Temperature is not something to be overlooked when it comes to battery performance, and it can have a profound effect on any battery. However, LiFePO4 has an excellent opportunity in extreme temperature transformations.
Final thoughts
If you’re looking for a safer solar generator with a better chance of providing you with long-term energy storage, then all Bluetti solar generators with the latest LFP technology are your best bet.
Models like the new AC200 MAX and AC300 modular power system have the potential to provide you with incredible energy storage.
For example, the AC300 is capable of combining 240V, 6,000W and a total of 24,576Wh with our Fusion Box Pro. This allows you to connect two units of the AC300 in series and up to 8 × B300 (four per AC300).
