The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.
During charge/discharge, the lithium ions are extracted concomitant with oxidation of Fe: LiFe II PO 4 ⇌ Fe III PO 4 + Li + + e −. Extraction of lithium from LiFePO 4 produces FePO 4 with a similar structure. FePO 4 adopts a P mnb space group with a unit cell volume of 272.4 Å 3, only slightly smaller than that of its lithiated precursor ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
Battery charging and discharging rates are often discussed by referencing a "C" rate of current. The C rate is that which would theoretically fully charge or discharge the battery in one hour. For example, trickle charging might be performed at C/20 (or a "20-hour" rate), while typical charging and discharging may occur at C/2 (two hours for ...
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready. [5]
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
The LiFePO4 data sheets I've seen say 3.6 or 3.65 V is the normal end of charge voltage for cycle charging, and 4.1 or 4.2 V is the "absolute maximum" (damage threshold). For long-term float (trickle charging) the voltage is about 0.1 or 0.2 V less than cycle charge. Different vendors have slightly different data sheets for these values.
