Lithium–silicon battery - Wikipedia

Lithium–silicon battery is a name used for a subclass of lithium-ion battery technology that employs a silicon-based anode and lithium ions as the charge carriers. Silicon based materials generally have a much larger specific capacity, for example 3600 mAh/g for pristine silicon, relative to graphite, which is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated

Silicon Carbide -vs- Tungsten Carbide

from an engineering standpoint. First, the coefficient of friction is lower in a silicon carbide seal. This benefits the pump by wasting less energy turning the seal and can prevent the faces from ‘seizing’ or ‘locking-up’ during times of inactivity. Second, the silicon carbide seal has a hardness approaching or greater than tungsten carbide. This yields a seal face that is scratch resistant and provides minimal wear. Third, silicon carbide …
