Pouch cells with silicon dominant anodes from E Magyst show less volume expansion than those with traditional graphite anodes, according to recent research.

The finding could lead to longer lasting batteries with less degradation over time.

E Magyst is a battery materials company that produces silicon dominant anodes. These anodes are made with a mixture of silicon and graphite, which the company says results in less volumetric expansion than pure silicon anodes.

To test this claim, researchers at the University of Texas at Austin conducted a series of tests on pouch cells with E Magyst anodes.

They found that the anodes experienced less than 1% volumetric expansion during charging and discharging cycles.

In contrast, pure silicon anodes typically experience 4-8% volumetric expansion.

The researchers say that the findings could lead to batteries with longer lifespans and less degradation over time.

E Magyst is not the only company working on silicon dominant anodes. Several other companies, including Samsung, LG, and Panasonic, are also researching and developing these materials.

The findings from this study could help battery makers develop longer lasting, more efficient batteries for electric vehicles and other applications.
