Revisiting Polytetrafluorethylene Binder for Solvent-Free Lithium-Ion Battery Anode Fabrication

A polymer scaffold binder structure for high capacity silicon anode of lithium-ion battery.

A sodium carboxymethyl cellulose porous scaffold has been obtained using the slurry spray technique as a binder for silicon anodes that demonstrate remarkably improved cycling stability and rate performance.

Lithium Ion Battery Anode Aging Mechanisms

Degradation mechanisms such as lithium plating, growth of the passivated surface film layer on the electrodes and loss of both recyclable lithium ions and electrode material adversely affect the longevity of the lithium ion battery. The anode electrode is very vulnerable to these degradation mechanisms. In this paper, the most common aging mechanisms occurring at the anode during the operation ...

Non-Annealed Graphene Paper as a Binder-Free Anode for Lithium-Ion Batteries

Non-annealed graphene paper, prepared via reduction of prefabricated graphene oxide paper with hydrazine hydrate, was employed as the sole component of a binder-free lithium-ion battery anode, circumventing the polymer binders and other additives required for the fabrication of conventional electrodes. The binder-free anode fabricated from this non-annealed paper possessed excellent cyclability...

Silicon Based Composite Anode for Lithium Ion Battery

3D graphene supported MoO2 for high performance binder-free lithium ion battery.

In this work, we report the synthesis of MoO2 nanoparticles grown on three dimensional graphene (3DG) via the reduction of α-MoO3 nanobelts through a facile chemical vapor deposition (CVD) approach under argon protection gas environment. In this synthesis approach, the presence of hydrophobic 3DG promoted the Volmer-Weber growth of MoO2 nanoparticles (30-60 nm). The as-prepared MoO2-3DG nanocom...
