Stanford, SLAC team cages silicon microparticles in graphene for stable, high-energy anode for Li-ion batteries
Green Car Congress
JANUARY 28, 2016
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).
