In the article below, we will try to introduce you to LifePO4 type batteries, which are more and more often used in construction machines as the main power source of the machine. Are these batteries a good choice? Judge it

LiFePO4 battery Introduction

Long story short, that’s how the LiFePO4 battery was born. (In 1996, by the University of Texas, to be exact). LiFePO4 is now known as the safest, most stable and most reliable lithium battery.

Lithium iron phosphate battery, is a type of lithium-ion battery that uses iron phosphate as the cathode material. LFP batteries are known for their high energy density, long life, and good performance at high temperatures. They are often used in applications where long life and good performance under adverse conditions are important, such as in electric vehicles, grid energy storage systems, and portable power tools. Lithium iron phosphate (LiFePO4) and lithium-ion batteries are commonly used in electric vehicles.

And last but not least, LiFePO4 batteries can not only reach 3,000-5,000 cycles or more… They can reach 100% depth of discharge (DOD). Why does that matter? Because that means, with LiFePO4 (unlike other batteries) you don’t have to worry about over discharging your battery

Lithium iron phosphate has a cathode of iron phosphate and an anode of graphite. It has a specific energy of 90/120 watt-hours per kilogram and a nominal voltage of 3.20V or 3.30V. The charge rate of lithium iron phosphate is 1C and the discharge rate of 1-25C.  

   LiFePO4 used in Zoomlion AWP machines battery has a built-in heating system that uses proprietary technology to obtain power from the charger itself. No additional components are required. The entire heating and charging process is completely seamless. Once you try to charge below 0°C, the heating system will automatically activate and automatically deactivate when it is no longer needed. The heating system does not take electricity from the battery, but from the charger to ensure that the battery does not discharge by itself. Just insert the battery into the lithium charger, the internal heating and monitoring system can complete the rest.  

LifePO4 can be used for a longer period of time as a result. In fact, you can use a quality LiFePO4 battery for many years longer than other battery types. It’s rated to last about 5,000 cycles.

Lithium Iron Phosphate  Offering a Range of Benefits

• Lithium iron phosphate batteries have a long life. Under the same conditions & can be used for 7 to10 years.
• The use of safe. Lithium iron phosphate battery has undergone rigorous safety testing, and even in traffic accidents, they will not explode.
• Fast charging. Use a special charger, 1.5C charging for 40 minutes, that can make the battery complete.
• Lithium iron phosphate battery high-temperature resistance, lithium iron phosphate battery hot air value can reach 350 to 500 degrees Celsius.
• Lithium iron phosphate batteries have a large capacity.
• Lithium iron phosphate battery has no memory effect.
• Lithium iron phosphate batteries are green, non-toxic, non-polluting, raw materials from a wide range of sources, and cheap.
• Lithium iron phosphate cathode vibration density is small, and the density is generally 0.8 to 1.3, so the volume is relatively large.
• The actual specific capacity is low, with poor electrical conductivity, slow diffusion of lithium ions, and high times when charging and discharging.
• Poor low-temperature performance of lithium iron phosphate batteries.
• Lithium iron phosphate overcharge resistance to 100% will not catch fire and explode; lithium batteries that reach the specified value will precipitate gas bulge.

Lithium iron phosphate has excellent thermal and chemical stability. This battery stays cool in higher temperatures. It is also incombustible when it is mishandled during rapid charges and discharges or when there are short circuit issues. Lithium iron phosphate does not normally experience thermal runaway, as the phosphate cathode will not burn or explode during overcharging or overheating as the battery remains cool.
