Recovery of critical metals from EV batteries via thermal treatment and leaching with sulphuric acid at ambient temperature.

In the upcoming years, todaýs e-mobility will challenge the capacity of sustainable recycling. Due to the presence of organic components (electrolyte, separator, casings, etc.), future recycling technologies will combine thermal pre-treatment followed by hydrometallurgical processing.

Hydrometallurgical recycling of EV lithium-ion batteries: Effects of incineration on the leaching efficiency of metals using sulfuric acid.

The growing demand for lithium-ion batteries will result in an increasing flow of spent batteries, which must be recycled to prevent environmental and health problems, while helping to mitigate the raw materials dependence and risks of shortage and promoting a circular economy. Combining pyrometallurgical and hydrometallurgical recycling approaches has been the focus of recent studies, since it can bring many advantages. In this work, the effects of incineration on the leaching efficiency of metals from EV LIBs were evaluated.

Incineration of EV Lithium-ion batteries as a pretreatment for recycling - Determination of the potential formation of hazardous by-products and effects on metal compounds.

In several industrial Lithium-ion batteries recycling processes, a thermal treatment with oxidative atmosphere is used to separate the battery components and to remove the organic components. This method is often combined with hydrometallurgical processes with the aim to increase the metal recovery rate or to improve the efficiency of the existing processes. Despite such efforts, the effects of a thermal treatment in an oxidative atmosphere on the microstructure and composition on cathode and anode materials has not been explored.

[Physical activity and cardiovascular mortality: epidemiology, screening and secondary prevention].

Sudden cardiac death in young athletes has become a highly visible public health issue and it has been studied for the last twenty years. In this article, we analyse the most recent literature about epidemiology and aetiology of sudden cardiac death in Switzerland in comparison to international data. We cover last recommendations for pre-participation screening in athletes and we briefly describe the strategies of secondary prevention.
