Silicon carbide: the great electrification enabler
When we discuss the technological advancement of electric vehicles and, indeed, other parts of the electrification value chain, one material comes up time after time. It isn’t a battery material, but a semiconductor. Up until recent years silicon was the primary material used to make semiconductors. Silicon’s a pretty reasonable semiconductor, but in EVs in particular its efficiency has been surpassed by another material which increases the efficiency of heat transfer and leads to less heat loss when switching between AC and DC power. That material is called silicon carbide (SiC) and it’s one of the most rapidly-growing markets within...
