Lithium iron phosphate serves as the positive electrode in these battery packs. This material offers a lot of advantages as far as cycle life and safety performance are concerned. The good thing is that these units can be charged up to 2000 times without the risk of explosion. Plus, they are easy to use when fixed in series. Given below are 8 advantages of these units.
1. High Charge/Discharge Efficiency
LiFePo4 is a type of lithium-ion battery. They are known as high-power battery packs, which is why they have a lot of advantages over Ni-Cd and Ni-MH ones. They offer much higher charge/discharge efficiency. You can enjoy up to 90% efficiency in case of discharge.
2. High Safety Performance
The good thing is that the P-O bond in these units is quite stable and won’t dispose or collapse, unlike a lithium cobaltate. These units can withstand high temperatures.
According to many reports, only a small area of the circuit caught fire when a short-circuit test was performed. In another experiment, they ran a high-voltage charge test. They found that the overcharge safety is quite higher than other types of batteries.
3. Long Cycle Life
LiFePo4 batteries are a type of lithium-ion battery that makes use of lithium iron phosphate. Lead-acid ones feature a life cycle of around 300 to 500 times. On the other hand, LiFePo4 ones can feature a lifecycle of over 2000 times.
As far as theoretical life is concerned, it can be up to 8 years in ideal conditions. If you use a special charger, you can fully charge the unit in 1.5 minutes to get 1.5C charging. On the other hand, you can’t enjoy this performance from a lead-acid battery.
4. Impressive Temperature Performance
The highest temperature these units can withstand is between 350 and 500 degrees. On the other hand, lithium manganate can’t withstand temperatures higher than 200 degrees. The temperature range is -20C and 75C.
5. High Capacity
Unlike ordinary units like lead-acid, these batteries offer a large capacity that varies between 5AH and 1000AH.
6. No Memory Effect
Often, rechargeable batteries can work very well in a variety of conditions when they are not completely discharged. In this case, these products experience a reduction in their capacity. And this concept is known as the memory effect.
The good news is that you don’t have such a problem with LiFePo4 batteries regardless of the state of charge.
If the capacity is the same, LiFePo4 batteries will be lighter than lead-acid ones. As a matter of fact, the weight difference will be 30% of that of lead-acid ones.
8. Environmentally Friendly
Finally, LiFePo4 batteries don’t contain heavy metals or other types of rare metals. In other words, they are free of toxic materials. Therefore, they are safe for the environment.
Long story short, these are some of the 8 primary advantages of LiFePo4 batteries over your regular lead-acid units.
