NorthVolt's CEO on Battery Prices, Recycling

The video discusses the decline in battery prices over recent years and anticipates further reductions, driven by improvements in energy density and economies of scale. It highlights the doubling of energy density every decade and the expected increase in battery demand, particularly in Europe. The supply chain challenges, including resource bottlenecks and the need for high-quality materials, are addressed. Current recycling methods are deemed inadequate, but research is ongoing to improve them. The video also emphasizes the need for infrastructure development to support the growing number of electric vehicles.
