Abstract

In response to the dual carbon policy, the proportion of clean energy power generation is increasing in the power system. Energy storage technology and related industries have also developed rapidly. However, the life-attenuation and safety problems faced by energy storage lithium batteries are becoming more and more serious. In order to clarify the aging evolution process of lithium batteries and solve the optimization problem of energy storage systems, we need to dig deeply into the mechanism of the accelerated aging rate inside and outside the lithium ion from the perspective of the safety and stability of a lithium battery in view of the complex and changeable actual working conditions during the operation of the battery. This paper takes a lithium-iron phosphate battery and a lithium-ion battery as examples to analyze. According to the specific scene of lithium battery operation, the actual operating conditions of lithium battery environmental impact factors and attenuation mechanisms are described in detail. The damage to the internal structure of lithium batteries was systematically analyzed. Furthermore, the correlation between the external influencing factors and the aging rate of lithium batteries under the coupling effect of internal failure mechanisms is analyzed. Finally, future energy storage failure analysis technology is anticipated, hoping to play a positive role in promoting the development of energy storage and lithium battery failure analysis technology.

锂储能电池老化风险评估与寿命预测技术综述

为响应双碳政策，清洁能源发电在电力系统中的比例不断增加。储能技术和相关产业也得到了快速发展。然而，储能锂电池面临的寿命衰减和安全问题也越来越严重。为了厘清锂电池的老化演化过程，解决储能系统的优化问题，需要针对锂电池运行过程中复杂多变的实际工况，从锂电池安全性和稳定性的角度深入挖掘锂离子内外加速老化的机理。本文以磷酸铁锂电池和锂离子电池为例进行分析。根据锂电池运行的具体场景，详细阐述了锂电池实际运行条件下的环境影响因素及衰减机理。系统分析了锂电池内部结构的损伤情况。此外，还分析了在内部失效机制耦合作用下，外部影响因素与锂电池老化率之间的相关性。最后，对未来储能失效分析技术进行了展望，希望对储能和锂电池失效分析技术的发展起到积极的推动作用。
