摘要

本文对NMC锂离子电池的实验研究进行了循环策略的比较。该研究的重点是在环境温度为0°C和应力因素取决于实际容量而不是标称容量的情况下，研究两种循环方案下电池的容量退化情况。循环后对容量损失进行了评估，结果显示，在方案1下循环的电池的容量损失分别为28.63%和25.5%，而在方案2下循环的电池的容量损失较低，分别为21.58%和20.73%。本文还介绍了放电电流和放电深度对容量利用率的影响，以支持开发适合实际应用的优化循环协议。

Performance characterization of lithium-ion battery and aging under constant stress conditions at low temperature

This paper presents a comparison on cycling strategies conducted on an experimental study on an NMC lithium-ion battery. The investigation focused on examining the capacity degradation on batteries subjected to two cycling protocols, conducted at an ambient temperature of 0 °C and stress factors that depend on actual capacity instead of nominal capacity. The capacity losses were evaluated post-cycling, revealing a degradation of 28.63 % and 25.5 % for cells subjected to Protocol 1, whereas cells cycled under Protocol 2 exhibited lower capacity losses of 21.58 % and 20.73 %.This paper also presents the impact of the discharging current and the depth of discharge on capacity utilization to support the development of optimized cycling protocols for practical applications.

期刊介绍： Microelectronics Reliability, is dedicated to disseminating the latest research results and related information on the reliability of microelectronic devices, circuits and systems, from materials, process and manufacturing, to design, testing and operation. The coverage of the journal includes the following topics: measurement, understanding and analysis; evaluation and prediction; modelling and simulation; methodologies and mitigation. Papers which combine reliability with other important areas of microelectronics engineering, such as design, fabrication, integration, testing, and field operation will also be welcome, and practical papers reporting case studies in the field and specific application domains are particularly encouraged. Most accepted papers will be published as Research Papers, describing significant advances and completed work. Papers reviewing important developing topics of general interest may be accepted for publication as Review Papers. Urgent communications of a more preliminary nature and short reports on completed practical work of current interest may be considered for publication as Research Notes. All contributions are subject to peer review by leading experts in the field.
