Lithium-ion batteries are rechargeable batteries that use lithium as their active components. Lithium Iron Phosphate Battery is a type of lithium-ion battery. Different lithium-ion batteries have different chemical properties, performance, cost, and safety characteristics.
Lithium batteries are applied in portable electronics, vehicles, medical equipment, and grid energy storage. Lithium iron phosphate is a popular choice of battery recognized by the manufacturing industry because of its low material cost, high-temperature resistance, and stability. The lithium iron phosphate batteries are also used in household solar energy systems, golf carts, outdoor portable energy storage, and electric motorcycles.
In this article, we will mainly discuss why lithium iron phosphate battery is a good choice.Let’s start it!
What is a lithium iron phosphate battery?
A lithium iron phosphate battery uses LiFePO4 as the cathode material and a graphitic carbon electrode with a metallic backing as the anode. It is the safest Lithium battery type on the market because the battery’s operating temperature range is wider and safer.
In addition, the cycle life of a lithium iron phosphate battery is more than 4 to 5 times that of other lithium-ion polymer batteries. This type of battery is small in size, light in weight, and the circle life can reach thousands of times.
Here are the typical specifications for a lithium iron phosphate battery:
- Voltage: 3.2 V nominal, ranging from 2.5-3.65 V
- Specific Energy: 90-120 Wh/kg
- Charge Rate: 1 C
- Discharge Rate: 1-25 C, possibly with 40 A pulses
- Life Cycle: 1,000-10,000 cycles, highly temperature dependent
- Thermal Runaway: 270 °C
- Temperature Range for Maximum Charging Rate: 0-45 °C
- Discharging Temperature Range: -20-60 °C
Why lithium iron phosphate batteries are better?
- Life cycle
Lithium iron phosphate batteries can reach 1,000-10,000 cyclesand can also reach 100% depth of discharge. This type of battery can handle high temperatures with minimal degradation.
Lithium iron phosphate batteries have a long lifespan for applications with embedded systems or require a long-term operation to charge. Other lithium-ion batteries’ higher energy density makes them more unstable, especially when dealing with higher operating temperature environments. Under this circumstance, it has a life cycle of 500-1,000 cycles.
- Long-term storage
When storing unused batteries, choosing chemistry that will not lose charge for a long time is important. Both lithium iron phosphate batteries and other lithium-ion batteries have good long-term storage benefits.
Lithium iron phosphate can be stored longer as it has a shelf life of 350 days. On the other hand, the shelf life is about 300 days for other lithium-ion.
Lithium iron phosphate batteries have excellent thermal and chemical stability. This type of battery stays cool in higher temperatures. Lithium iron phosphate is non-flammable when improperly handled or short-circuited during rapid charging and discharging.
However, the chemistry of other lithium-ion batteries doesn’t have the same safety advantages as lithium iron phosphate. It’s high energy density has the disadvantage of causing battery instability. Due to the heat up faster during charging, other lithium-ion batteries can have thermal runaway.
Another safety advantage of lithium iron phosphate is the disposal of the battery after use. A lithium-ion battery made of lithium cobalt dioxide chemistry is a hazardous material. Therefore, you need to dispose of it carefully because this battery can cause allergic reactions to the eyes and skin when exposed. On the other hand, lithium iron phosphate is non-toxic and easier to handle.
- Excellent efficiency and performance
- Charge efficiency: Lithium iron phosphate batteries will be fully charged in 2 hours or less.
- Self-discharge rate when not in use: Only 2% per month
- Consistent power: Even if the battery life is less than 50%, it can maintain the same current intensity.
