Batteries play a crucial role in the transition towards climate neutrality and circular economy. With the aim of achieving carbon neutrality by 2050, the shift from fossil fuels to electromobility is imperative. New regulations and the energy crisis anticipate a rapid growth in battery demand in the coming years. The European Union has committed to establishing a comprehensive regulatory framework covering the entire lifecycle of batteries, emphasizing reduced use of critical raw materials, waste management, recycling, and second-life applications. Lithium-ion batteries dominate the electric mobility landscape, and their demand is projected to surge. To address issues related to the extraction and purification of critical raw materials, alternative solutions are required.
