Customer ServiceOuyang et al. systematically investigated the effects of charging rate and charging cut-off voltage on the capacity of lithium iron phosphate batteries at −10 ℃. Their findings indicated that capacity degradation accelerates notably when the charging rate exceeds 0.25 C or the charging cut-off voltage surpasses 3.55 V.
During the long charging/discharging process, the irreversible loss of active lithium inside the LFP battery leads to the degradation of the battery's performance. Researchers have developed several methods to achieve cathode material recovery from spent LFP batteries, such as hydrometallurgy, pyrometallurgy, and direct regeneration.
The degradation modes of the LIBs encompass the loss of active positive electrode material (LLAM_Po), the loss of active negative electrode material (LLAM_Ne), the loss of lithium inventory (LLLI), and the increase of internal resistance [2, 4].
Obviously, the more severe the degradation of the battery, the deeper the overgrowth of SEI film on the negative electrode . The overgrowth of SEI films depletes the active Li + from the cathode material, which in turn deepens the degradation of the battery capacity. Fig. 5. a) Flow chart of the experiment.
But there’s a twist. Lithium iron phosphate (LFP) batteries are cheaper to produce and more stable than traditional nickel-based chemistries. A new study from a Tesla-funded lab found that LFP batteries degrade faster when fully charged. Repeated charging at a higher state of charge increases negative reactions within a pack.
To reveal the aging mechanism, the differential voltage (DV) curves and the variation rule of 10 s internal resistance at different aging stages of the batteries are analyzed. Finally, the aging mechanism of the whole life cycle for LIBs at low temperatures is revealed from both thermodynamic and kinetic perspectives.
