A lithium iron phosphate (LFP) battery
A type of lithium-ion battery that is capable of charging and discharging at high speeds compared to other types of batteries. It is a rechargeable battery consisting of LiFePO4 as its cathode material; hence the name.
Lithium iron phosphate batteries have several distinctive features, including:
- Better power density.
- Low discharge rate.
- Flat discharge curve.
- Less heating.
- A higher number of charge cycles.
- Increased safety.
Lithium iron phosphate (LFP) batteries are also known as lithium ferrophosphate batteries.
LiFePO4 batteries are delivering a constant voltage and also has a comparatively higher charge cycle
The major distinction that lithium iron phosphate batteries have from other li-ion batteries is that LFP is capable of delivering a constant voltage and also has a comparatively higher charge cycle, in the range of about 2000 (100% DOD) and 5000 cycles (80% DOD). LFP batteries are environmentally safe and structurally stable. They have a lower energy density and low discharge rate. They do not heat up easily and are relatively cooler than other batteries. The chemistry of the battery saves it from thermal runaway, and hence it is considered to be safe for home use.
Due to their constant voltage and safe discharge, LFPs have found applications in cars, bicycles and solar devices. They are also used as replacements for costly lead-acid starter batteries. They are well suited for applications that require high-load currents and endurance. They are easy to store and carry due to their lightweight and ability to provide huge amounts of energy. They are widely used in portable electronic devices like laptops and mobile phones.
A recent improvement over the original lithium iron phosphate cathode material by MIT has allowed these batteries to be charged up to 100 times faster than the previous speed. An improvised coating of an ion conductor onto the LFP has enabled the acceleration of ions, and thus the charging time has been greatly reduced.
