Electrochemical Characterization of Cu-Catalysed Si ...

Silicon (Si) nanowires (NWs) grown on stainless-steel substrates by Cu-catalysed Chemical Vapour Deposition (CVD) have been prepared to be used as anodes in lithium-ion batteries. The use of NWs can overcome the problems related to the Si volume changes occurring during lithium alloying by reducing stress relaxation and preventing material fragmentation.

Confronting Issues of the Practical Implementation of …

While the silicon anode has been vigorously studied for the high-energy lithium-ion battery (LIB), the practical application of the silicon anode still seems tardy. To stimulate the implementation of Si anodes in high-energy LIB, we discuss practical issues of Si anodes with the conventional electrochemical cell design. This Perspective reminds the reader about the major aim of developing the ...

Anode Materials for Lithium-ion Batteries | NEI …

Anode materials are the negative electrode in lithium-ion batteries and are paired with cathode materials in a lithium-ion cell. The anode materials in lithium-ion cells act as the host where they reversibly allow lithium-ion intercalation / deintercallation during charge / discharge cycles.

Selection of Optimum Binder for Silicon Powder …

The Si anode undergoes repeated and rapid expansion and contraction due to the storage and release of lithium ions [44,45,46,47], thus separating from the binder. As a result, the binder is no longer able to support active materials and the electrode’s structure collapses. This leads to the rapid deterioration of the charge–discharge behavior.
