Silicon anodes vs. solid-state batteriesAnalysts say silicon anodes theoretically offer 10 times the energy density as graphite, which are commonly used in battery anodes today. Silicon anodes, for example, are known to swell significantly during charging, which reduces the battery's longevity. Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China. Nonetheless, analysts remain skeptical about when solid-state batteries will actually make it to market. "However, there are significant technical challenges going to 100% silicon anode such as silicon expansion affecting the longevity of the batteries and currently there are several routes to produce silicon anodes," he added.
