2020/2/13Main Text The realization of next-generation Li-ion batteries (LIBs) relies on the availability of energy-dense electrode materials. 1, 2 A variety of emerging anode and cathode materials have been intensively investigated. 3, 4 Among them, silicon (Si), which has a high theoretical specific capacity (4,200 mAh g −1, Li 22 Si 5), has been considered a promising anode material for next

Caging Silicon Anodes with Graphene

Caging Silicon Anodes with Graphene Dean Sigler 02/05/2016 Announcements, Batteries, Sustainable Aviation Leave a Comment Dr. Yi Cui of Stanford University has expanded the idea of "battery" to include conductive ink on paper, fruit-like clusters of energy-storing capsules, and now, nano-sized graphene cages in which the energy can romp like a hamster in a plastic ball.

Synthesis of Multilayer Graphene Balls by Carbon

Three-dimensional (3D) structured graphene is a material of great interest due to its diverse applications in electronics, catalytic electrodes, and sensors. However, the preparation of 3D structured graphene is still challenging. Here, we report the fabrication of multilayer graphene balls (GBs) by template-directed carbon segregation using nickel nanoparticles (Ni-NPs) as template materials

Emerging Opportunities for Two

graphene cages on micrometer-sized Si particles. Si is one of the most promising anode materials due to its high theoretical capacity of 4200 mAhg−1. However, due to a 300% volume expansion during electrochemical cycling, Si particles suffer from mechanical fracturing, leading to uncontrolled SEI formation and loss of electrical contact, as schematically depicted in Figure 4a.
