High capacity silicon/carbon composite anode materials for lithium ion batteries

Nano‐Structured Phosphorus Composite as High‐Capacity Anode Materials for Lithium Batteries

“…Graphite (372 mA h g À1 ) is presently used as an anode material for lithium-ion batteries, but higher capacity anode materials are being extensively researched. [1][2][3][4][5][6] Among the many possible alternatives, a lot of work has been devoted to metal oxides, [7,8] Sn-based composites, [9] Si-based composites, [10][11][12] because of their ability to react reversibly with large amounts of Li per formula unit. Elemental phosphorus is another potentially attractive anode material with a theoretical specific capacity of 2595 mA h g À1 , assuming a complete reaction, 3 Li + P!Li 3 P. [6,13,14] Phosphorus has three main allotropes: white, red, and black.…”

Electrochemical Characteristics of Silicon-carbon Composite Anodes for Lithium Rechargeable Batteries

“…They reported that the graphite powders had a role as a buffer and matrix for the Si NPs during lithium intercalation and deintercalation, and the mechanical stability of the composite was increased [23]. Yang et al disclosed that the coarse composite powder exhibited higher capacity and better cycle stability than the fine one [24]. They revealed that Si particles were easily detached from a carbon matrix, such as carbon black.…”

A Review on Nanocomposite Materials for Rechargeable Li-ion Batteries

“…The graphite-Si composite anodes with carbon coating showed better performance than Si alone, but quick degradation of cycle life is still a concern in these type of materials [144,145]. The carbon and metal coating techniques were also applied to improve the cycle life and Coulombic efficiency of Si anodes [146,147].…”
