Part 5. Global situation of lithium iron phosphate materials. Lithium iron phosphate is at the forefront of research and development in the global battery industry. Its importance is underscored by its dominant role in the production of batteries for electric vehicles (EVs), renewable energy storage systems, and portable electronic devices.
To investigate the aging mechanism of battery cycle performance in low temperatures, this paper conducts aging experiments throughout the whole life cycle at −10 ℃ for lithium-ion batteries with a nominal capacity of 1 Ah. Three different charging rates (0.3 C, 0.65 C, and 1 C) are employed. Additionally, capacity calibration tests are conducted at 25 ℃ every 10
Lithium hydroxide: The chemical formula is LiOH, which is another main raw material for the preparation of lithium iron phosphate and provides lithium ions (Li+).

In the context of prioritizing safety, lithium iron phosphate (LiFePO 4) batteries have once again garnered attention due to their exceptionally stable structure and moderate voltage levels throughout the charge-discharge cycle, resulting in significantly enhanced safety performance .
However, the thriving state of the lithium iron phosphate battery sector suggests that a significant influx of decommissioned lithium iron phosphate batteries is imminent. The recycling of these batteries not only mitigates diverse environmental risks but also decreases manufacturing expenses and fosters economic gains.
This outcome is due to a considerable decrease in Li + transport capabilities within the electrode, particularly leading to a dramatic decrease in the electrochemical capacity and power performance of the electrolyte. Therefore, the design of low-temperature electrolytes is important for the further commercial application of LiFePO 4 batteries.
Furthermore, the proposed low-temperature liquid-phase method can be easily scalable and implemented in various regions worldwide, thereby promoting the circular economy of lithium-ion batteries and reducing reliance on virgin resources (Supplementary Discussion 5). 4. Conclusions
The persistence of the olivine structure and the subsequent capacity reduction are attributable to the loss of active lithium and the migration of Fe 2+ ions towards vacant lithium sites (Sławiński et al., 2019). Hence, the regeneration of LiFePO 4 crucially hinges upon the reinstatement of active lithium and the rectification of anti-site defects.
However, LiFePO 4 -based battery applications are seriously limited when they are operated in a cold climate. This outcome is due to a considerable decrease in Li + transport capabilities within the electrode, particularly leading to a dramatic decrease in the electrochemical capacity and power performance of the electrolyte.
