Inorganic Compounds as Binders for Si-Alloy Anodes

Toward efficient binders for Li-ion battery Si-based anodes: polyacrylic acid.

Si-based Li-ion battery anodes offer specific capacity an order of magnitude beyond that of conventional graphite. However, the formation of stable Si anodes is a challenge because of significant volume changes occurring during their electrochemical alloying and dealloying with Li. Binder selection and optimization may allow significant improvements in the stability of Si-based anodes. Most stu...

High Performance Li4Ti5O12/Si Composite Anodes for Li-Ion Batteries

Improving the energy capacity of spinel Li₄Ti₅O12 (LTO) is very important to utilize it as a high-performance Li-ion battery (LIB) electrode. In this work, LTO/Si composites with different weight ratios were prepared and tested as anodes. The anodic and cathodic peaks from both LTO and silicon were apparent in the composites, indicating that each component was active upon Li⁺ insertion and extr...

Synthesis of Si-Sb-ZnO Composites as High-Performance Anodes for Lithium-ion Batteries

The Si-Sb-ZnO composites were prepared by a chemical reduction-mechanical alloying method and were employed as anode materials for lithium-ion batteries. The electrochemical performance of the Si-Sb alloy was significantly improved by the addition of ZnO nanoparticles. Especially, the initial specific charge and discharge capacities for Si-Sb-(ZnO)0.3 composite were 845.1 and 1301.5 mAh/g, resp...
