Due to the extreme volume expansion of silicon/carbon materials, they are vulnerable to fractured delamination, leading to capacity fading during use. One approach to mitigate these effects is application of mechanical pressure on the cell. A 2019 study published in the Journal of the Electrical Chemical Society Tekscan used pressure mapping sensors and software as a visual tool and means of data gathering over time to reveal hot spots at various pressure applications. The team used this data to help identify optimal mechanical pressures aimed at preserving battery life.
