The increasing demand for electrochemical energy storage devices such as battery cells both for electromobility and stationary applications [1] poses a need for improving the energy density and performance of current lithium-ion cells. One strategy is to use silicon-based anodes. The main challenge of this material is still the increased volume expansion during lithiation, which […]

Introduction In recent years, there has been a significant upsurge in the popularity of electric vehicles (EVs). Li-ion batteries are the most popular energy sources used in EVs due to their high energy density and low self-discharge. However, these batteries have an optimal average temperature range of operation as well as a temperature uniformity requirement […]

Battery cells are a crucial component of battery electric vehicles (BEVs) and stationary storage systems, significantly impacting cost, sustainability, performance, and safety. They account for 25–40 % of a BEV’s total cost and 40–60 % of its carbon footprint (CF). Sodium-ion batteries (SIBs) are often considered a more cost-effective and sustainable alternative to lithium-ion batteries […]

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 […]

Cells testing is a topic largely reproduced in research papers about Lithium-Ion batteries, with known general effects from its parameters: higher currents produce increased heat, mechanical stress and Li concentration gradients; low temperatures favour Li plating, high temperatures accelerate kinetics of parasitic reactions, and many other parameters reportedly generate specific consequences to each cell chemistry […]
