The lithium iron phosphate battery (LiFePO 4 or LFP) does not satisfactorily deliver the necessary high rates and low temperatures due to its low Li + diffusivity, which greatly limits its applications.
Jiang Fan et al. studied the effects of different low-temperature voltage profiles on lithium ion batteries and suggested that lithium plating will occur at high-rate charging . Low temperatures are unavoidable in practical use, however, although they are known to damage the battery.
In this paper, cycle life tests are conducted to reveal the influence of the charging current rate and the cut-off voltage limit on the aging mechanisms of a large format LiFePO4battery at a low temperature (−10 °C). The capacity degradation rates accelerate rapidly after the charging current reaches 0.25 C or the cut-off voltage reaches 3.55 V.
The pervasively acknowledged aging mechanisms of lithium batteries are the loss of lithium ion (LLI), the loss of electrode active material (LAM), and an increase in resistance (IIR) , . LLI occurs mainly on the surface of the anode due to SEI decomposition and regeneration.
In the past decade, LiFePO 4 (LFP), which belongs to the olivine group, has attracted considerable attention as cathode material for lithium-ion batteries because of its inherent merits including environmental benignity, potential for low cost, long cycle ability and excellent thermal stability [1, 3].
Lithium iron phosphate (LiFePO 4) is emerging as a key cathode material for the next generation of high-performance lithium-ion batteries, owing to its unparalleled combination of affordability, stability, and extended cycle life.
