Chessboard

The coutilization of silicon (Si) and graphite is a commercially viable method for realizing high-energy-density anode materials for lithium-ion batteries. However, the high cost and complicated manufacturing process for Si/graphite composite anodes hinder their practical application. Herein, a chessboard-like Si/graphite anode with a homogeneous distribution of Si on the surface of graphite

Graphene

2011/11/25Conventional graphite anodes display a theoretical specific capacity of only 372 mAh g-1, making it a weak candidate for anodes of Li-ion batteries. The GS-Si nanocomposites were synthesised using a spray-drying technique which requires "no surfactant, no filtration or washing processes and no high vacuum conditions."

PNNL team develops carbon nanotube

2020/5/1Silicon is an appealing anode material for Li-ion batteries because it can hold about 10 times the electrical charge per gram compared to graphite. However, silicon suffers from large volume change during lithiation/delithiation, leading to structure failure. Although nanostructured Si can mitigate that structure failure, nanomaterials, with their high surface

Silicon anode structure generates new potential for lithium

2021/2/5Silicon anodes can store ten times as much charge in a given volume than graphite anodes—a whole order of magnitude higher in terms of energy density, said Dr. Haro. The problem is, as the lithium ions move into the anode, the volume change is huge, up to around 400%, which causes the electrode to fracture and break.
