Current-day EVs generally use graphite anode batteries, which tend to provide shorter range compared to their gas-guzzling brethren, according to the researchers. Silicon anodes, on the other hand, have ten times the capacity — but are much worse at holding their capacity over time.

Frying Batteries

The team, led by Hun-Gi Jung, came up with a way to keep these silicon anodes stable by using “a simple thermal process used for frying food,” according to a statement, which involves the use of water, oil, and starch.
