        Why to choose LIFEPO4 battery as the energy sourse of smart all in one solar street light


 Why LiFePO4 Battery



New patternSafeEV power Li-ion battery LiFePO4 material is safe than LiCoO2 & LiMn2O4 for it’s stable structure can be kept very well under continuous charging & discharging situations.  nThe superior high temperature & storage performance make LiFePO4 the most suitable one for Li-ion battery positive material. nLonger than 1000 cycle life is more suitable for application use.

 LiFePO4 battery could reach 2000 DOD (Depth of Discharge) cycles but still remaining 70% initial capacity, comparing to traditional lead acid battery with only average 300-500 cycles or some very best with 1000 cycles


Safety 

LiFePO4 battery is not like Li-ion battery that used in our cell phone or mobile device that has explosion risk in extreme condition such as crash, burn or threw into fire etc.   LiFePO4 has been proved by industry as very stable and safe chemistry structure and has very minimum risk to cause safety accident even in the most extreme condition.


 High Energy Density 

In the same volume, LiFePO4 has much higher capacity than lead acid battery because of its higher energy density. It could save a lot of volume and weight in the design and also save the transportation cost


 No Memory Effect 

LiFePO4 can discharge almost 100% of its initial capacity without damaging the battery structure, unlike lead acid battery that could only discharge 65-70% of initial capacity. The over discharge on lead acid battery will damage the battery´s cycle life dramatically. 


 Environmental Friendly

Unlike lead acid battery, LiFePO4 battery doesn´t include hazard material or heavy metal. It could be recycled much easier with very low cost.
