Formation is one of the most important and time-consuming process step in the production of lithium-ion batteries. During the first charge of the formation process the decomposition layers on the electrodes, the solid electrolyte interphase (SEI) on the negative (N) electrode and the cathode electrolyte interphase (CEI) on the positive (P) electrode, are formed. The […]

Electrochemical Impedance Spectroscopy (EIS) is a well-known technique in battery technology due to being non-destructive and providing crucial insights about what’s happening in the battery. One of the biggest challenges that electrochemists encounter during impedance measurements is the ambiguity of the analysis of EIS data. Equivalent circuit modelling is the state of art analysis method […]

Lithium-sulfur batteries are a type of rechargeable battery technology that has gained attention due to their high energy density and potential for lower cost compared to traditional lithium-ion batteries. However, Li-S batteries suffer from capacity fade over multiple charge-discharge cycles. This is due to the dissolution and diffusion of intermediate lithium polysulfide species, which can […]

Accurate battery lifetime prediction is important for maintenance, warranties, and cell design. However, manufacturing variability and usage-dependent degradation make life prediction challenging. Here, we investigate new features derived from capacity-voltage data in early life to predict the lifetime of cells cycled under varying charge rates, discharge rates, and depths of discharge. The early-life features capture […]

Laboratory-based battery ageing studies rely primarily on constant-current cycle loads to age the battery at defined conditions. In the next step, the battery degradation can be modelled by correlating the resulting degradation to the varied constant-current cycle conditions, such as temperature, charging and discharging current, cycle depth, and soc range. However, the load profiles of […]

Although lithium-ion batteries (LIBs) are widely used, recycling them poses significant social and technological difficulties. Recovering useful raw materials from spent LIBs requires efficient processes. Studies currently examine the effectiveness of electrolytes like NaCl, K2CO3, and other aqueous electrolytes in promoting effective internal and external discharge below 2V, thereby minimizing pole corrosion. Mechanical recycling requires […]
