“…To illustrate this, Asakura et al [65] show that a battery life halved for an 0.1V augmentation of the charging voltage, the EOL is considered here as 70% of initial capacity. Discharge voltage inuences the battery ageing through the impedance augmentation [66,42].…”

Lithium-ion batteries have become the focus of research interest, thanks to their numerous benets for vehicle applications. One main limitation of these technologies resides in the battery ageing. The eects of battery ageing limit its performance and occur throughout its whole life, even if the battery is used or not, which is a major drawback on real usage. Furthermore, degradations take place in every condition, but in dierent proportions as usage and external conditions interact to provoke degradations. The ageing phenomena are highly complicated to characterize due to the factors cross-dependence. This paper reviews various aspects of recent research and developments, from dierent elds, on Lithium-ion battery ageing mechanisms and estimations. A summary of techniques, models and algorithms used for battery ageing estimation (SOH, RUL), going from a detailed electrochemical approach to statistical methods based on data, are presented.

“…Focusing, in particular, on cycle aging, in addition to the temperature and SoC level, important factors for battery aging are the charging/discharging cut-off voltages. The authors in [26] showed that high charging cut-off voltages accelerated the aging phenomena, particularly the capacity fade, while low discharging cut-off voltages affected the aging, particularly the power fade [27].…”

“…29 To prepare the desired LFP, a variety of synthetic methods have been optimized, including solid phase syntheses, 30,31 sol-gel processes, 32,33 a microwave technique, 34 templatebased methods, 35,36 solvothermal treatments, and so on. Among them, solvothermal syntheses 37,38 excel at morphology and size control, as well as providing moderate reaction condition. 3D hierarchical LiFePO 4 particles networked with electronically conducting multi-walled carbon nanotubes were prepared using the hydrothermal method approach.…”

A LiFePO 4 /C composite was directly synthesized via a simple solvothermal method. Ferric nitrate nonahydrate, FeĲNO 3 ) 3 •9H 2 O, was selected as a low cost iron source in the ethanol process and glucose as the carbon source. Through SEM images, it was found that the concentration of the glucose solution has an important influence on the morphology of particles. The samples were characterized by Raman spectroscopy and TEM measurements, showing the formation of graphitic carbon, which is desirable for its contribution to the electronic conductivity. XPS analysis verified that Fe 3+ was almost completely reduced to Fe 2+ . CV (cyclic voltammetry), EIS (electrochemical impendence spectroscopy), and galvanostatic charge/discharge tests were conducted to further study the electrochemical properties of the LiFePO 4 /C composite. The results reveal that the LiFePO 4 /C composite with a rodlike shape has the highest specific capacity of 147 mA h g −1 at 0.1C, and the capacity retention remains 100% after 50 cycles.
