Life cycle analysis of lithium-ion batteries

To protect the earth’s ecological environment and respond to the call for energy conservation, emission reduction, and sustainable development policies, the application of new energy technologies is becoming more and more widespread. Due to the advantages of high working voltage, small size, light weight, high energy, no memory effect, no pollution, small self-discharge, long cycle life, etc., lithium batteries have become a superior energy carrier in the 21st century. With the use of new energy vehicles, the performance of lithium-ion batteries is inevitably degraded. To ensure the safety of new energy vehicles during the whole period of use, it is crucial to analyze and study the whole life cycle of lithium-ion batteries. This chapter addresses the life cycle analysis of lithium-ion batteries, first outlining the current state of development of lithium-ion batteries and the significance of life cycle analysis, then discussing the impact of the aging mechanism factors and external conditions of lithium-ion batteries on the life of lithium-ion batteries, and finally introducing the most important part of life cycle analysis—remaining useful life prediction and the analysis of multiple prediction methods to achieve accurate and reliable prediction. It is essential to ensure the stability and safety of battery power supply systems, and is also crucial for battery life cycle analysis.
