Lithium plating is a key degradation mechanism which results from operating in cold temperatures (or high C-rates) and can ultimately contribute to catastrophic failure of lithium-ion batteries via short circuit. Predicting the onset of Li plating via non-invasive methods could allow for BMS’s to modify cell operating conditions to minimise cell degradation and extend cell […]

Higher energy density, greater reliability, and better safety are the main goals of lithium-ion batteries (LIBs) research and development. Electrolytes with improved stability and non-flammability for realizing high-energy density and high-safety LIBs have been actively pursued. The electrolyte is thus a critical component that determines the performance of LIBs. This study proposes a high-entropy electrolyte […]

Introduction All-solid-state lithium-ion batteries (ASS-LiBs) are attracting attention as next-generation batteries for electric vehicles because of their high capacity and safety. High safety comes from the solid electrolytes, materials unique to ASS-LiBs. However, the productivity of solid electrolytes tends to be low because they are primally produced by a batch-type wet synthesis. For the practical […]

The storage of large quantities of Li-ion batteries is necessary in various industries and warehouses around the world. However, an increasing number of fire incidents is continuing to raise questions on the risk and safety of storage configurations of Li-ion batteries, because the fires have the potential to spread rapidly with minor chance for firefighting […]

The lifetime of Li-ion Batteries (LIB) depends on the reversible amount of Li ions and electrons (= active Li), defining Li inventory and cell capacity. Active Li loss (ALL) occurs at the negative electrode (= anode) predominantly via electrolyte reduction and formation of the solid electrolyte interphase (SEI). Nevertheless, given interference of the cathode, anode […]

This paper presents an aging-aware controller for photovoltaic (PV) battery systems aimed at mitigating battery degradation to enhance the operational lifespan and economic viability of energy storage systems. The study involves a one-year simulation of an optimization-based home energy management system (HEMS) utilizing the DESO optimization algorithm, grounded in Stochastic Dynamic Programming (SDP). The HEMS […]

In this study, we present a JMAK-based model to analyze lithium plating in lithium-ion batteries. The onset of plating is identified by a bell-shaped curve during the constant-voltage charging phase. By fitting the model to this curve, it analyzes plating quantity, growth rate, and dimensionality, providing key insights into plating morphology for different charging conditions. […]

Modules composed of parallel-connected cells are employed as the building block of battery packs in order to achieve an increase in output current and system reliability. Given that the current distribution among cells is not known beforehand, standard electrochemical models are not well conditioned for the simulation of parallel-connected cells. Additionally, interconnection and contact resistances, […]
