Benefits of Lifepo4 battery

Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency, etc.

Benefits of Lifepo4 battery

◆ Excellent Safety Performance

LiFeP04 batteries completely solve the hidden safety problems of LiCoO2 and LiMn2O4 batteries. LiFeP04 battery is currently the world's only absolutely safe lithium ion battery. Its stability at high temperature can reach 400-500 times, which ensure the inner high safety of battery. It will not explode or burn due to overcharge, high temperature, short circuit and impact.

◆ Long Cycle Life

It has high cycle times, at room temperature 1C charge-discharge cycle more than 2000 times, the capacity retention rate is more than 80%, which is 8 times of Lead-acid battery, 3 times of Ni-MH battery, 4 times of LiCoO2,4-5 times of LiMn2O4.

◆ Environment-Friendly

It does not include any heavy metal or rare metal. It is non-toxic, non-polluting.

◆ Light Weight, Small Volume

Its weight is 1 /3 of lead-acid battery, volume is 2/3 of lead-acid battery.

◆ No-Memory Effect

If rechargeable battery does not completely charge or discharge for a long time,it is easy to leave traces in battery, which will reduce the battery capacity, this phenomenon in known as memory effect. Like Ni-MH and Ni-Cd battery they have memorability, but LIFeP04 battery does not have this phenomenon, no matter what state the battery is, it can be charged and used, without discharging first and then charge.

◆ High Temperature Resistance

It can be discharged between temperature -41 °C and +80°C. LiFeP04 electric heat peak can reach 350°C-500°C. But the LiCoO2 and LiMn2O4 can reach only about 200°C.
