Is LiFePO4 Battery Worth It in Australia?

What Is a LiFePO4 Battery?

LiFePO4 battery technology has improved greatly since its introduction in the late 1990s. Today's LiFePO4 batteries use much better chemistry than traditional Li-ion batteries, making them more efficient in international applications. LiFePO4 batteries are safe, environmentally friendly, and longest-lasting. They are known for their unique chemistry, lithium iron phosphate, or LFP, for short.

LiFePO4 batteries consist of an anode (LiFePO4), a cathode (usually graphite), an electrolyte (usually a lithium salt dissolved in a metal) and a separator. Unlike other lithium-ion batteries that use cobalt, nickel, or manganese, LiFePO4 batteries use lithium iron phosphate as the cathode material. 

As a cathode material, LiFePO4 offers many advantages regarding energy density, power output, and safety. Therefore, compared with traditional lead-acid and other lithium-ion batteries, LiFePO4 batteries have many advantages, including high capacity, stable performance and long service life.

The capacity (measured in ampere-hours Ah) is the energy stored in a battery or power source. Most lithium batteries have a rated voltage of 3.2V or 3.7V per cell, with LiFePO4 batteries having the highest rated voltage of 3.3V per cell.

LiFePO4's high voltage rating allows it to hold more power than other types of batteries, such as lead-acid batteries, making it ideal for applications requiring a long life cycle, such as electric vehicles and outdoor solar projects. In addition, LiFePO4 batteries have a higher watt-hour rating, charge faster, and are more efficient than other types of batteries, making them more popular for a wide range of applications.

LiFePO4 Battery Charging & Discharging

It is essential to avoid overcharging or over-discharging, as this will damage the LiFePO4 battery and shorten its life. Therefore, please read the following information to understand better charging and discharging LiFePO4 batteries.

How LiFePO4 Battery Charging Works 

When an LFP battery is charged, lithium ions move from the surface of the lithium iron phosphate crystal to the surface of the graphite crystal. Then, under electrical energy, lithium ions enter the electrolyte, pass through the diaphragm and finally enter the graphite network.

And electrons flow through the conductor to the aluminium foil collector at the anode. (Electrons flow through the tabs, battery poles, external circuits, negative electrodes, and negative tabs to the copper foil collector at the negative electrode.)

Then, it flows through the conductor to the graphite negative electrode to balance the charge on the negative electrode. After the lithium ions are deintercalated from the lithium iron phosphate, the lithium iron phosphate is converted into iron phosphate.

Note: Separator: Made of a polymer (plastic) that has many tiny pores that allow lithium ions to pass through easily.

How LiFePO4 Battery Discharging Works

When the LFP battery is discharged, lithium ions escape from the graphite crystals, enter the electrolyte, and pass through the separator. The lithium ions then migrate through the electrolyte to the surface of the lithium iron phosphate crystals and then embed into the lithium iron phosphate lattice through the surface.

At the same time, the battery's electrical energy flows through the conductor to the copper foil collector at the negative electrode. (The electrical energy flows through the tabs, the negative battery pole, the external circuit, the positive pole, and the positive tab and flows to the aluminium foil collector at the positive electrode of the battery.) 

Finally, the electrical energy flows through the conductor to the lithium iron phosphate positive electrode to balance the charge of the positive electrode.

How to Properly Charge and Discharge LiFePO4 Batteries? 

The charging and discharging of LiFePO4 batteries are critical to their operation and long-term performance. Therefore, it is necessary to ensure that the battery is charged and discharged appropriately.

How to Charge LiFePO4 Batteries Correctly?

A voltage stabilisation circuit and a corresponding LiFePO4 battery charging circuit are required to charge LiFePO4 batteries properly. The CV charging method is used to charge LiFePO4 batteries, that is, constant current first and constant voltage later. (0.3 C for continuous current and 3.65 V for constant voltage are recommended)

Solar panels cannot charge LiFePO4 batteries directly because the voltage of solar panels is unstable.

Generators cannot charge LiFePO4 batteries directly because the electricity they generate is AC or pulsed DC.

How to Properly Discharge a LiFePO4 Battery?

Here are the steps to properly discharge a LiFePO4 battery:

Step 1: Determine a safe discharge rate. LiFePO4 batteries have a recommended maximum discharge rate, usually between 1C and 3C. 1C means the battery can be discharged at a rate that will completely drain it in 1 hour. 3C means it can be drained in 1/3 hour.

Step 2: Connect the load. Connect the LiFePO4 battery to the device or load you want to discharge, making sure the connection is correct and the polarity is correct (positive to positive, negative to negative).

Step 3: Monitor the voltage. A voltmeter is used to monitor the voltage of the LiFePO4 battery continuously during discharge. (The discharge voltage of a LiFePO4 battery should not be less than 2.5V per cell.)

Step 4: Stop discharging at the right time. Stop discharging when the LiFePO4 battery voltage reaches the recommended minimum voltage of 2.5V per cell.

Step 5: Store the battery properly. After discharge, store the LiFePO4 battery in a cool, dry place. Avoid storing LiFePO4 batteries in a fully charged or fully discharged state. The ideal storage state for LiFePO4 batteries is approximately 50% charge.
