Description:Abstract
To realize a
more holistic approach to electrification in society, not only is it mandatory
that we disengage from non-renewable fuels while adopting new approaches to
energy storage, but we must realize actual environmental benefits from this
transition. Given that the majority of greenhouse gas emissions in battery
value chains originate from material mining and production, there is
exceptional incentive to find alternate routes to superior lithium ion battery
(LIB) components.
Combustion of
rice husks generates 100s of gigawatts of green electricity annually in the
U.S. alone, and coincidentally, ≈150k tons of RHA (90 wt % silica ≈ 10 wt %
carbon). We have learned to use RHA to make a number of LIB components
including Li+ conducting electrolytes, silicon, silicon carbide, and silicon
oxynitride anode materials that offer capacities >950 mAh g-1 competitive
with porous Si metal.
