The external force applied on a li-ion cell when assembling it in a battery pack manifests as an important variable to consider in its design. This study investigates the influence of external pressure on automotive and industrial applications oriented high-capacity pouch and prismatic NMC/G lithium-ion cells in the behaviour and lifetime of the battery. Three […]

Cell-to-cell variations play a significant role in the commercialisation of sodium-ion batteries (SIB). With first SIBs entering the open market in consumer-friendly 18650 packages, this work aims to provide insight into the typical cell metrics as well as the effects of cyclic ageing on these cells. To provide a baseline, the results are compared to […]

To ensure an extensive market penetration of electric vehicles, among others, lithium ion batteries (LIBs) need to achieve a further reduction of the environmental impact and costs of the electrode manufacturing process. Aqueous processing of LIB cathode electrodes has become a vital strategy to substitute state-of-the-art teratogenic N-Methyl-2-pyrrolidone (NMP) solvent and the fluorinated polymer polyvinylidene […]

The recently found two-dimensional class of layered materials, MXenes, has attracted attention as potential anode materials in Lithium-ion batteries due to their high theoretical capacity, their long cycling stability as well as their high conductivity. Aiming to alter the electronic properties, we report on the effect of a 1% Mn-doping in V_(2)C MXenes, i.e. V_(2-x)Mn_(x)C. […]

With the increasing use of renewable energy sources, efficient short- and long-time storage technologies have become essential for balancing supply and demand. There is no single energy storage solution that is ideal for every time-scale application. Electrochemical energy storage systems, typically tailored for either high-power or high-energy applications, encounter operational limitations when deployed outside their […]

Multiple measurement methods were developed for determining a battery degradation level, competing in their efficiency and speed. The simplest of them are based on remaining capacity estimation or serial resistance measurement via short current pulse of appropriate frequency. While others include sophisticated treatment of electrochemical impedance spectra and extend to the hybrid approaches, aiming a […]

Multi-Walled Carbon Nanotubes (MWCNTs) have been recognized as a beneficial conductive additive material in Silicon-based anodes owing to their unique characteristics, including high electronic conductivity and the capability to alleviate the volume expansion of lithiated Silicon anode-based battery cells. Nevertheless, both CNTs and Silicon irreversibly consume a high quantity of Li-Ion inventory to form the […]
