As the pandemic is subsiding, global travel, van life, and camping are back on track. People are running to exotic and unknown destinations to find some much-needed fun and peace. At this time, the market is flooded with alternative power solutions like solar power stations, diesel generators, inverters, etc. Most of the devices for power generation use lithium-ion battery chemistries like NCM and NCA. However, Bluetti is at the forefront of technological innovation and uses LiFePo4 (LFP) batteries for its solar generators.

The LFP battery is less expensive than some of the other lithium-ion chemistries, like NCA and NCM as it does not use cobalt. Moreover, it offers long cycle life, fast charging, and low toxicity. So let’s take a detailed look at the LFP battery technology used by Bluetti.

LiFePo4 Batteries

LiFePO4 is a natural mineral of the olivine family. In 1996 it was identified as a cathode material belonging to the polyanion class for use in batteries. Its anode material is LiaC6, and the cathode material is LiFePO4, with the carrier being Li+. Due to the nano-scale phosphate cathode material found in the battery, LFP batteries provide some of the best electrochemical performance with added lower resistance on the market. 

Advantages of LiFePo4 Batteries:

• Thermal stability 
• Long life cycle
• Higher current rating
• An extra layer of safety
• No maintenance
• Lightweight and portable
• Improved discharge and charge efficiency
• Low toxicity

How do LiFePo4 Batteries work?

An LFP battery is essentially made up of the following components: Positive electrode (cathode), Negative electrode (anode), Electrolyte, Separator, Lithium metal oxide (LiFePO4), Graphite, Lithium salt, and Polymer membrane Charging. 

Charging the Battery:

When a LiFePO4 battery is being charged, lithium ions are released from the cathode and move to the anode using the electrolyte.

Discharging: 

When a power load is applied to the battery, the opposite reaction takes place and Lithium ions move from the anode to the cathode.

Electricity:

This movement of the lithium ions from the cathode to anode and vice-versa creates an electron flow between these two electrodes, which generates an electric charge and powers your devices. 

Why LiFePo4 Batteries are the perfect companions for your solar generators?

• Long Life Span: The greatest advantage of an LFP battery over a lithium-ion NCM / NCA battery is its ability to charge and discharge over a thousand times. For e.g. Bluetti’s largest solar generator can discharge over 3500times. This is a significant decision-making factor as LFP technology gives you not only high-quality batteries but also long-lasting ones. 
• Highly efficient: Unlike lead-acid batteries, LFP ones are highly efficient because they can discharge over 90% of their capacity. This means you get the most out of your solar generator for as little space used as possible.
• Zero maintenance: Another big advantage of LFP technology is that it requires no active maintenance. LFP batteries require pretty much no maintenance. This means you do not need to do anything to extend its lifespan. You can simply charge and discharge as you see fit. 
• Lightweight and portable: When compared to other similar battery technologies available in the market, LiFePo4 batteries are much lighter.  This is particularly important when their application is found inside a solar generator as lesser weight means higher mobility. For e.g. Bluetti’s new AC200 MAX weighs only 61.9lbs (28.1kg). This may sound like a lot but compared to its discharge power and energy density, 61 pounds is nothing.
• High Safety: LiFePO4 batteries are the safest lithium-ion batteries on the market. These batteries are encased in an airtight aluminum case, specifically designed to withstand temperature, pressure variations, punctures, and impacts.
• Extreme Temperatures: Temperature is not something to overlook when it comes to battery performance, as it can have a profound effect on any battery. However, LiFePO4 stands the best chance during extreme temperature variations. Thus Bluetti’s solar generators are able to operate in a wide range of temperatures, which makes them desirable in different surroundings and environments. 

Why Bluetti is a better and cheaper option?

Let’s now compare Bluettis Solar generators with other manufacturers like Jackerry and Ecoflow:

*Please note that Bluetti uses LiFePO4, Jackery lithium-ion, and Ecoflow NCM. 

**We could not find a comparable capacity size for the Jackery, so we included their largest capacity generator, which is 1,534 Wh

When it comes to energy storage, one cannot simply rely on the actual buying price of the solar generator (up-front cost).  We also need to take into account the total energy in watt-hours that the solar generator can store and release (the charge/discharge cycle) during its lifetime. Thus we need to find the  LCOS or Levelized Cost Of Storage in USD/Wh.

LCOS = Upfront Cost / (total kWh capacity x (DoD %) x cycle life) 

Let’s work out the LCOS for each solar generator manufacturer and their respective product models. 

Bluetti

2 kWh x 0.9 x 3500 = 6300

$1,799 / 6300 = $0,285 per kWh

Jackery 

1.5 kWh x 0.8 x 500 = 600

$1,599 / 600 = $2.67 per kWh

Ecoflow

2 kWh x 0.8 x 800 = 1280

$1,899 / 1280 = $1.48 per kWh

As we can see when working out the LCOS, Bluetti is by far the much cheaper option over the long run, as the LiFePO4 technology lasts much longer than both lithium-ion and NCM. Please note that the above LCOS includes other components such as the charge controller and inverter, as these two components are included in the upfront purchasing price. 

Conclusion:

We now know the importance of LFP battery technology and how it has revolutionized the portable power sector. If you are looking for a high-quality, long-lasting, safe, and zero-maintenance power solution then Bluetti stands out in the market with its use of LiFePo4 batteries. Models such as the new AC200 MAX and the AC300 modular power system are capable of providing you with incredible amounts of energy storage.
