Lithium Iron Phosphate Battery Discharge Curve

A drop in replacement for lead acid batteries.

Lithium iron phosphate battery discharge curve.

Indeed the voltage. Lithium iron phosphate technology has the flattest discharge curve which makes it very difficult to estimate soc on a simple voltage measurement. The discharge voltage curves of li manganese li phosphate and nmc are very flat and 80 percent of the stored energy remains in the flat voltage profile. The stage 1 of a lithium battery can take as little as one hour to complete making a lithium battery available for use four times faster than sla.

Stage 1 battery charging is typically done at 30 100 0 3c to 1 0c current of the capacity rating of the battery. Its specific capacity is more than 145ah kg. In comparison the lithium iron phosphate lifepo4 cell is a non aqueous system having 3 2v as its nominal voltage during discharge.

Stage 1 of the sla chart above takes four hours to complete. Lithium iron phosphate chemistry eliminates t he r isk of ex pl on or c mb un de to h gh i ac ove r ng. Therefore the gravimetric energy density of lifepo4 battery is 130wh kg four times higher than that of lead acid battery 35wh kg. This opens up new possibility for a simple but very long life backup battery in 3 3 volt systems.

The lithium iron phosphate battery lifepo 4 battery or lfp battery lithium ferrophosphate is a type of lithium ion battery using lifepo 4 as the cathode material on a battery this is the positive side and a graphitic carbon electrode with a metallic backing as the anode the energy density of lifepo 4 is lower than that of lithium cobalt oxide licoo 2 chemistry and also has a lower. The voltage curve of a lithium ion battery is much different than that of a lead acid battery. Delivers twice power of lead acid battery even high discharge rate while maintaining high energy capacity. Lead based batteries have a more linear discharge where voltage consistently drops over time.

While voltage based soc works reasonably well for a lead acid battery that has rested the flat discharge curve of nickel and lithium based batteries renders the voltage method impracticable. However lithium ion batteries have a much flatter discharge curve which means that over a wide operating range the voltage at the battery terminals changes very slightly.
