AI Customer ServiceHowever, due to its porosity, a small amount of electrolyte can still diffuse into the SEI film, leading to the thickening of the SEI film and the loss of active lithium. This thickening leads to capacity decay of lithium-ion batteries during storage, and its decay rate is related to the square root of time.
The health status of lithium-ion batteries is limited by various factors such as capacity, internal resistance, and multiplicity. The estimation of the SOH of lithium-ion batteries can effectively determine the real-time and future operating conditions within the battery and is of great research importance.
Nonetheless, life cycle assessment (LCA) is a powerful tool to inform the development of better-performing batteries with reduced environmental burden. This review explores common practices in lithium-ion battery LCAs and makes recommendations for how future studies can be more interpretable, representative, and impactful.
This paper presents two empirical cycling degradation models designed for NMC and LFP lithium-ion battery chemistries. The novel contribution of the models consists on representing the effect of the degradation stress factors as function of battery chemistries, rather than single cell references as typically approached in the literature.
The external/internal factors that affect the cycle life of lithium-ion batteries were systematically reviewed. Three prediction methods were described and compared for SOH and remaining battery life estimation.
Therefore, the experiment data showed that power lithium-ion batteries directly affected the cycle life of the battery pack and that the battery pack cycle life could not reach the cycle life of a single cell (as elaborated in Fig. 14, Fig. 15).
