“…11 shows the capacity fading trends of the LFP/graphite cells held at different voltages and those cycled between 2.0 and 3.9 V. For the cells held at different voltages, the capacity loss occurs mainly during the initial 20 days and the capacity seems to level off during the following 40 days. The relatively rapid capacity loss of cells during the initial storage is believed to be associated with SEI rearrangement of the electrodes [39][40][41][42][43]. By comparison, for the cell galvanostatically cycled between 2.0 and 3.9 V, the capacity loss deteriorated greatly over time.…”

“…4 refers in the literature to the dynamic evolution of the negative electrode layer SEI, responsible of the insertion and deinsertion of lithium ions into graphite [19]. As described before, this phenomenon is mentioned as a major source of aging.…”

In this work, we highlight the performance recovery phenomenon when aging high-power lithium-ion batteries used in HEV application. This phenomenon consists in the increase on the battery capacity when we stop power-cycling. We demonstrate the dependency of this phenomenon on the stop-SOC value. Keeping battery at a fully discharged state potentially preserves a large amount of charge from the SEI-electrolyte interaction when they are in the positive electrode during rest time. Results from power cycling and combined, calendar/power cycling, aging of a 12 Ah-commercialized Lithium-ion battery at 55°C have been presented and obtained results have been discussed.

“…The difference in surface potential was attributed on the deposition of the passive SEI film on the continuously cycled cathode, resulting in capacity loss in the battery. Sankarasubramanian and Krishnamurthy (2012) developed a one dimensional capacity fade model incorporating solvent diffusion and the kinetics of SEI formation. Furthermore, surface characterization equipments were used to determine the SEI thickness.…”

The electric vehicle industry has been rapidly developing internationally. Electric vehicle batteries (EVBs) are perceived as a low environmental impact energy storage technology. While the service life of an EVB is relatively long, a significant number of battery packs will reach the end of their service lives eventually. The end-of-life (EOL) EVBs may still have appreciable residual value for remanufacturing and secondary use. Some solid-electrolyte interface (SEI) layers will persist on the surface of electrodes deposit after a period of continuous cycling, causing the battery degradation and failure. An approach to battery end-of-life management was introduced involving remanufacturing of the cathode from EOL lithium-ion battery electrodes, and a recent study on remanufacturing process of the degraded EVBs using pulse laser to radiate SEI on the electrode surface was presented in this paper, here on a laboratory scale. Based on experimental data, the SEI film removal was carried out with laser energy intensity ranging from 0.035 to 0.169 J/mm 2 . The remanufactured cathodes were characterized through a combination of scanning electron microscopy, Fourier transform infrared spectroscopy, and wavelength dispersive spectrometer, respectively. The experimental results indicated that the remanufacturing treatments were successful in removing the EOL by-products (e.g., SEI films) and upgrading the cathode to its pre-cycling functionality. It is suggested that the fade capacity of a lithium-ion battery can be recovered by using laser radiation method.
