Polycaprolactone(PCL) solid polymer electrolytes (SPEs) offers a biodegradable sustainable alternative material for SPE battery systems, the interfacial dynamics between PCL and Li metal are insufficiently explored. This study utilizes operando ATR-FTIR spectroscopy to compare the interfacial behaviors of crosslinked (cl) and non-crosslinked PCL5LiTFSI SPEs. A series of electrochemical measurement reveals that the crosslinked network provides […]

Charge transfer kinetics strongly impact high-power applications of lithium-ion batteries such as fast charging. At such high current applications, the classical Butler¬¬ Volmer (BV) model may fail to predict overpotentials without deviations [1]. One of the approaches that has succeeded to explain these deviations is the coupled ion-electron transfer (CIET) theory [2]; however, its validation […]

The expansion of use cases of high-power lithium-ion batteries (LIBs) lead to an enormous growth of battery industry. Fast-charging of these batteries is one major issue cell manufacturers and users are both facing nowadays. Faster C-rates enable shorter charging periods but also can lead to cell ageing and in worst cases to safety critical states […]

Accelerated Infrared Drying of NMP-Based Cathodes: Scaling Production for Efficient Battery Life Cycles Objective Electrode drying is the most energy-intensive bottleneck in the battery production life cycle, accounting for up to 48% of total manufacturing energy consumption. This work targets the production process of NMP-based NMC cathodes by implementing high-intensity infrared (IR) drying as a […]

Sodium-ion batteries (SIB) are said to be a more sustainable battery technology compared to conventional lithium-ion batteries (LIB) due to their use of less critical raw materials. The rising demand for batteries has led to an increased interest in SIBs in the past years. One promising class of active materials are Prussian blue analogues (PBAs), […]

In this study we investigate the direct emissions of a state-of-the-art battery gigafactory in Germany. We show that in a typical, state-of-the-art battery gigafactory large amounts of factory internal, process specific emissions are generated, namely 80 t/a of dusts, 510–850 t/a of gases and 2700 t/a of sludges. This are about 2.7% of the material […]

The economic potential of stationary storage systems can be strongly influenced by how battery ageing is accounted for in energy trading optimisation. State of the art trading algorithms typically rely on highly simplified degradation models that neglect the pronounced effect of certain stress factor such as depth of discharge (DoD) on capacity fade, resulting in […]

The presence of polyvinyl fluoride (PVDF) in spent lithium-ion batteries (black mass) promotes agglomeration and encapsulation of recoverable valuable metals such as lithium, nickel, manganese and cobalt, thereby reducing metal extraction efficiency. This study investigates the effect of pre-treatment methods such as calcination and solvent based delamination on the hydrometallurgical leaching of valuable metals from […]

This work presents a methodology for developing State of Charge (SoC) estimation algorithms for lithium-ion (Li-ion) and sodium-ion (Na-ion) batteries using Long Short-Term Memory (LSTM) recurrent neural networks combined with Transfer Learning (TL). Accurate SoC estimation is a key requirement for advanced Battery Management Systems (BMS), as internal battery states such as SoC, State of […]
