Suitable for renewable energy?If the lithium ion battery has an application for residential RE storage, the optimal person is a large-scale prismatic lithium iron phosphate (LIFEPO4, LFP) battery. But how do they lead technology?
weight. The weight is compared to the available energy storage, one LFP is about one-third of the lead-acid (LA) battery. This has a great advantage of mobile applications, such as ship / leisure cars, but for stationary regeneration applications, weight is usually only replaced by battery.
space. About half of the volume of a LA battery or the like, a less space occupied by a LFP. This can be the advantage of mobile applications, but the application, size or volume of the still RE is usually not a determinant.
Low temperature capacity. The storage capacity of the location area is reduced by 50% in -4 ¡ã F, compared to 8% of LFP. Keep the lead-acid batteries, allowing them to keep the reasonable capacity in the cold climate can be challenging and given the advantages of a LFP. However, the LFP battery should generally be charged at a slower speed, and the cold usually does not exceed one C / 10 at ambient temperature below 32 ¡ã F. (For example, if you have a 200 AH battery, the charging speed of C / 10 is 20 A.)
Discharge voltage and impedance. The discharge voltage of the LA battery has a significant taper to reduce the national charge, and the voltage of the LFP battery remains quite stable until they are close to complete discharge. A LFP has an internal resistance (impedance) of approximately one-quarter LA battery to reduce the energy of the input heat battery. These are combined to improve the efficiency of the system and prevent the DC voltage plummeted, which can affect the voltage sensitive device.
Charging and discharging current. LFP can be safely charged and discharged in a higher current than the LA battery. However, rare earth applications relatively low currents (relative to electric vehicle applications) make this in this regard.
Self-discharge. At room temperature, an idle (stored or disconnected) LA battery loses 5% to 15% of its capacitance, while 1% to 3% is an LFP. In energy use is only an occasional (such as yacht, RV, or vacation cabbage) RE, or during the low RE source, this may be a very useful attribute.
