Why choose LiFePO4 batteries ?
LiFePO4 batteries use chemistries derived from lithium ions and have many advantages and disadvantages compared to other lithium ion battery chemistries. However, there is a big difference.
Compared to other Li-ion methods, LFP chemistry provides longer cycle life. Like nickel-based rechargeable batteries (unlike other lithium-ion batteries), LiFePO4 batteries have a very constant discharge voltage. During discharge, the voltage remains close to 3.2 V until the battery is depleted. This allows the battery to deliver almost full power before discharging, and can greatly simplify or even eliminate the need for a voltage regulator circuit.
Since the nominal output is 3.2 V, four batteries can be placed in series with a nominal voltage of 12.8V. This is close to the nominal voltage of a six-cell lead-acid battery. LFP batteries have good safety characteristics, which makes LFP a good potential replacement for lead-acid batteries in applications such as automotive and solar, provided that the charging system must be adapted to not damage LFP batteries due to excessive charging voltages (over 3.6) Case. DC volts per cell while charging), temperature-based voltage compensation, equalization attempts, or continuous trickle charging. Before assembling the battery pack, the LFP cells must be balanced at least initially, and protection systems also need to be implemented to ensure that no cell can be discharged below 2.5 V, otherwise severe damage will occur in most cases.
The use of phosphate avoids the cost and environmental concerns of cobalt, especially the problem of cobalt entering the environment through improper disposal.
Compared to other lithium chemistries, LFP degrades much more slowly in the fully charged state. This makes LFP a good choice for backup.
