Si has been regarded as the most promising candidate for the next generation of Li-ion batteries (LIBs), because of its high theoretical capacity, abundant natural sources, and low electrochemical potential. Nonetheless, several technical challenges still limit its commercialization.

The graphene cage acts as a mechanically strong and flexible buffer during deep cycling, allowing the silicon microparticles to expand and fracture within the cage while retaining electrical connectivity on both the particle and electrode level. —Yi Cui. Here we introduce a method to encapsulate Si microparticles (∼1–3 µm).

Sustain 80-85% round trip efficiency in PSOC applications; 90-95% in deep cycle applications. Compared to Li-ion batteries: PbC batteries are more affordable [3x] than lithium-ion or supercapacitors; PbC batteries have recycling value at end-of-life [$35/lbs], while Lithium-ion batteries have recycling cost at end-of-life [~$75/lbs].
