12V LFeLi Battery

12V LFeLi Battery

Lithium iron Phosphate battery (LiFePO4) has a nominal voltage of 48VDC. It is comprised by 16 cells of 3.2V each. The internal structure of LiFePO4 battery cell is shown in the figure on the right. Shown is the olivine structure of LiFePO4 as the positive electrode of cell. Aluminum foil functions as current collector of positive pole. A polymer membrane separates positive and negative electrodes of the cell. The electron (e-) can't pass through the polymer separator but Li+ can pass through it freely. The negative electrode which consists of graphite is shown in the figure on the right. Copper foil is the current collector of negative electrode. There is organic electrolyte in the cell which is sealed by Al-plastic composite film.

Features Application Curves Specification

1.Environment-friendly , not containing heavy metals.

2.Longer Cycle Life, Offers up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership.  

3.Lighter Weight, About 40% of the weight of a comparable lead acid battery. A 'drop in' replacement for lead acid batteries.

4.Low self-discharge rate (per month): ≤2%, no memory effect.

5.Higher Power, Delivers twice power of lead acid battery, even high discharge rate, while maintaining high energy capacity. 

6.Superior Safety, Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situation.  

7. Wide operating temperature range (-20~+60℃) and good high temperature performance.

8.Excellent fast charging performance, after fast charging with 1C current, the capacity can reach 95% of rate capacity in one hours.
