Nanostructuring Strategies for Silicon‐based Anodes in Lithium‐ion Batteries: Tuning Areal Silicon Loading, SEI Formation/Irreversible Capacity Loss, Rate Capability Retention and Electrode Durability

Autor: Mariam Ezzedine, Fatme Jardali, Ileana Florea, Mihai‐Robert Zamfir, Costel‐Sorin Cojocaru

Publikováno v: Batteries & Supercaps. 6

Silicon is one of the most promising anode materials for Lithium-ion batteries. Silicon endures volume changes upon cycling, which leads to subsequent pulverization and capacity fading. These drawbacks lead to a poor lifespan and hamper the commercia

Publikováno v: CrystEngComm. 18:207-212

In order to reduce substrate costs and increase light absorption, solar cells based on semiconductor wire arrays are currently being actively studied. Whether built with Si, InP or other semiconductor materials, wire-based cells invariably use a tran

Highly Interconnected Si Nanowires for Improved Stability Li-Ion Battery Anodes

Autor: SeungNam Cha, Chandan Biswas, Mihai Robert Zamfir, Fei Yao, Didier Pribat, Jong Min Kim, Kang Pyo So, Young Hee Lee, SeongMin Kim, Hung T. Nguyen

Publikováno v: Advanced Energy Materials. 1:1154-1161

Silicon exhibits the largest known capacity for Li insertion in anodes of Li-ion batteries. However, because of large volume expansion/phase changes upon alloying, Si becomes powder-like after a few charge-discharge cycles. Various approaches have be
