Lithium-ion batteries in battery-electric vehicles must balance charging speed, degradation, and safety to ensure optimal performance. High charging speeds can lead to lithium plating, resulting in lithium inventory loss, solid electrolyte interphase (SEI) build-up, and dendrite formation. These phenomena contribute to capacity reduction, increased resistance, and potential safety risks. Controlling the charging current based on […]

The increasing demand for electric mobility underscores the need for precise and efficient battery diagnostics, particularly within Battery Management Systems (BMS) that monitor important parameters such as State of Charge (SoC) and State of Health (SoH). Conventional methods like Coulomb Counting and Open-Circuit Voltage measurements provide limited precision and fail to capture the underlying chemical […]

This study explores how external mechanical pressure affects the performance of commercial prismatic lithium-ion cells over their lifespan. While previous research has focused on pressure effects in pristine cells, this work emphasizes the changes that occur as the cells age. High-capacity NMC/graphite prismatic cells are used, and various levels of external pressure are aplied while […]

In recent years, the interest in sodium battery technology has been increasing, mainly due to the high abundance of sodium, which positions the sodium battery as a complementary technology to the current lithium battery. In this work, we focus on the development of a sodium solid-state battery, in which we study and evaluate the behavior […]

The quickest and simplest way to benchmark cells against one another is through the comparison of datasheets and rapid standardised testing of cells. However, typical datasheets provide information based on cells tested under constant current load profiles in controlled ambient temperature. These test conditions are unrepresentative of most real applications. This work selects and benchmarks […]

The maritime sector must increasingly become more sustainable and meet climate goals. As a result, more battery-electric and hybrid ships are being built and retrofitted. Safety is crucial since the battery system is vital for maneuverability. Hence, classification societies require regular health assessments of these systems. Currently, battery capacity is measured annually through complete charge […]

Today, lithium-ion battery production technology is based on a wet electrode manufacturing process. The electrodes’ constituent materials, the active material, an electron conductive material and a polymeric binding material, are mixed together with the use of organic solvents or water in order to create a slurry. The role of the solvent is to relax and […]

This work aims to discuss different approaches to model accurately the charge behavior of LFP cells under different operating conditions. Equivalent electrical circuit and physico-chemical models are compared. Parameterization tests are carried out on a small 2.5 Ah LFP cell. Model is validated by means of different validation profiles, considering temperature and current (constant and […]
