Cyclic charging and discharging of Lithium-ion (Li-ion) battery cells lead to the contraction and expansion of the battery electrodes. These contractions and expansions result in the development of internal stresses within the electrodes, further culminating in the growth of cracks. Typically, the cracks in anodes lead to an increase in the surface area hence facilitating a faster SEI layer

Falling costs for battery cells have long been perceived as an essential condition for the widespread success of electromobility. And so more and more of the technological innovations introduced into the battery are aimed at reducing costs, even if at the same time features such as vehicle range tend to deteriorate.
Battery raw materials like lithium carbonate (Li 2 CO 3), lithium hydroxide (LiOH), nickel (Ni) and cobalt (Co) have experienced significant price fluctuations over the past five years. Figures 1 and 2 show the development of material spot prices between 2018 and 2023.
The global economic slowdown due to the Covid19 pandemic, for example, may have led to the expectation of decreasing demand for battery raw materials. As a result, prices fell in 2019 and the beginning of 2020.
