The first laboratory experiments with lithium-silicon materials took place in the early to mid 1970s. Silicon carbon composite anodes were first reported in 2002 by Yoshio. Studies of these composite materials have shown that the capacities are a weighted average of the two end members (graphite and silicon). On cycling, electronic isolation of the silicon particles tends to occur with the capacity falling off to the capacity of the graphite component. This effect has bee.
Lithium–silicon batteries are lithium-ion batteries that employ 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.
Lithium-silicon batteries also include cell configurations where silicon is in compounds that may, at low voltage, store lithium by a displacement reaction, including silicon oxycarbide, silicon monoxide or silicon nitride. The first laboratory experiments with lithium-silicon materials took place in the early to mid 1970s.
Why do we use silicon in lithium-ion batteries?
By using abundant, pure silicon in lithium-ion batteries, with seamless manufacturing integration, we're able to reduce the battery production costs by up to 30%. Our high-capacity silicon anode enables up to a 50% jump in energy density compared to conventional lithium-ion batteries.
Are lithium-silicon batteries better than Li-ion batteries?
Lithium-silicon batteries move the world toward the electrification of everything because they are significantly more highly performing than li-ion batteries using graphite across all performance metrics. Lithium-silicon batteries have:
Can a lithium-silicon battery hold more ions than graphite?
A long-standing goal for anode innovation with lithium batteries has been to leverage silicon as an active material inside of the anode, creating a lithium-silicon battery. Lithium-silicon batteries have the potential to hold huge amounts of lithium ions due to silicon's 10x higher capacity than graphite.
Our high-capacity silicon anode enables up to a 50% jump in energy density compared to conventional lithium-ion batteries. Produced with advanced electrolyte material, our silicon anode battery delivers performance while increasing safety by mitigating the risks of thermal runaway.
