Title: Performance Analysis of Lithium-Ion Battery Considering Round Trip Efficiency
Abstract: Recent times have witnessed significant progress in battery technology due to the growing demand for energy storage systems in various applications. Consequently, battery efficiency has become a crucial aspect of modern battery technology since it directly influences battery performance and lifespan. To guarantee the optimal performance and longevity of batteries, it is essential to measure and understand the battery’s round-trip efficiency, which refers to the ratio of energy delivered from the battery during discharge to the energy stored in the battery at the time charging process. The objective of the current study is to investigate and analyse the lithium-ion battery round-trip efficiency. A mathematical model has been established to calculate the battery’s coulombic efficiency over a charge-discharge cycle. A comprehensive analysis has been carried out on the developed model to evaluate and compare different battery aspects. By elaborating a correlation between battery efficiency - ambient temperature, battery age, discharge capacity, capacity retention, and round-trip time, this study provides valuable insights into battery performance and optimization. This information will help in understanding battery behaviour and the impact of efficiency on battery technology development. Ignoring battery efficiency can result in lower performance and reduced battery lifespan, hampering battery technology progress. This study aims to contribute to the field’s advancement by providing valuable data on battery efficiency.
