Keheng’s Lithium Iron Phosphate (LiFePO4 batteries) are fast becoming the industry’s first choice. But what does lithium iron phosphate (LiFePO4) mean? How are lithium iron phosphate (LiFePO4) batteries different from other types of batteries? (Do not confuse lithium-ion batteries; they are not the same.) Let’s explore these questions in depth.
What is a lithium iron phosphate battery?
Lithium iron phosphate batteries are a variety of lithium batteries made up of lithium iron phosphate. Other members of the lithium battery family include:
- Lithium cobalt oxide (LiCoO22)
- Lithium nickel manganese cobalt oxide (LiNiMnCoO2)
- Lithium Titanate (LTO)
- Lithium manganese oxide (LiMn2O4)
- Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2)
CHEMISTRY AND BATTERY INNOVATIONS You may remember learning about these elements in chemistry class, and you’ve spent many hours memorizing the periodic table or doing experiments. Sometimes students become interested in these experiments and choose chemistry as a career. It was these chemists who discovered the best lithium combination for batteries.
This is how the lithium iron phosphate battery was born. (To be exact, it was invented by the University of Texas in 1996). Lithium Iron Phosphate batteries are now considered to be the safest, most stable and reliable lithium batteries available.
A Brief History of the Lithium Iron Phosphate Battery The lithium iron phosphate battery was originally developed by John B. Goodenough and Arumugam Manthiram. They discovered the materials used in lithium-ion batteries. Anode materials are not suitable for use in lithium-ion batteries because they tend to short-circuit prematurely.
The scientists found that anode materials are a better choice for lithium-ion batteries, as evidenced by the LiFePO4 battery variant. Fast-forward: We increased stability and conductivity, made a series of improvements, and voila! The LiFePO4 battery was born.
Today, rechargeable lithium iron phosphate batteries are everywhere. They have a wide range of applications, from boats and solar systems to electric and gas-powered vehicles.
Keheng’s LiFePO4 batteries are cobalt-free and have a lower long-term cost than most alternatives. They are harmless and have a longer service life. The future looks bright for LiFePO4 batteries.
But what are the advantages of LiFePO4 batteries?
Lithium Iron Phosphate vs Lithium Ion Batteries Now that we understand what lithium iron phosphate batteries are, let’s look at why they are superior to lithium ion and other lithium batteries.
Compared to lithium-ion batteries, lithium iron phosphate batteries have a lower energy density and are therefore not suitable for wearable devices such as watches. However, for applications such as solar energy systems, RVs, golf carts, bass boats, semi-trucks, and electric motorcycles, lithium iron phosphate batteries are the best choice. Why?
First, lithium iron phosphate batteries have more than four times the cycle life of lithium-ion batteries.
Lithium is also the safest type of lithium battery available, safer than lithium-ion and other types of batteries.
Finally, lithium iron phosphate batteries are not only capable of 3,000-5,000 cycles or more, but they are also capable of 100% depth of discharge (DOD). This means you don’t have to worry about over-discharging your LiFePO4 battery. You can also use them for longer periods of time. In fact, high-quality lithium iron phosphate batteries last several years longer than other types of batteries. These batteries are rated for about 5,000 cycles – about ten years. As a result, the average cost is significantly lower over time.
Lifepo4 battery VS. Li-ion battery
Safe, Stable Chemistry The safety of lithium batteries is critical. Lithium-ion laptop batteries are notorious for “blowing up”, making them a popular choice.
Advantages of Keheng lithium iron phosphate battery
One of the outstanding features of Keheng lithium iron phosphate battery is its unparalleled safety. Of all lithium battery types, lithium iron phosphate is considered by far the safest.

Comparison of LiFePO4 with other rechargeable batteries
When comparing ACE Lithium Iron Phosphate batteries to other rechargeable batteries on the market, the advantages are clear.
Lead Acid Batteries
Although lead-acid batteries seem to be more economical at the beginning, they end up costing more due to frequent maintenance and shorter service life. LiFePO4 batteries last 2-4 times longer than lead-acid batteries and do not require any maintenance.
Gel Battery
Both gel batteries and lithium iron phosphate batteries do not require frequent charging and can maintain their charge during storage. However, gel batteries charge slowly and must be disconnected after a full charge to avoid damage.
AGM Batteries
AGM batteries are more costly and easily damaged if discharged beyond 50% capacity. In contrast, Keheng lithium iron phosphate batteries can be fully discharged without causing any damage.
