Nano- and bulk-silicon-based insertion anodes for lithium-ion secondary cells

Nano-silicon-based disordered carbon composites prepared by mechanical milling and pyrolysis have been examined as anodes of a lithium ion cell. Electrochemical measurements show that the chargedischarge capacity of

We report microstructures on the surface of graphite particles found in practicable carbon anodes by means of high-resolution transmission electron microscopy. The surfaces consist of closed-edge structures

Nano-structures on the surface of graphite based carbon particles have been investigated by means of high resolution transmission electron nnicroscopy. The surfaces consist of "closed-edge" structures in a similar manner as carbon nano-tube. That…

Despite the advantageous characteristics of a carbon nanotube CNT, commercially reliable Si-CNT nanocomposites have not yet been developed due to the difficulties in effective dispersion of CNTs and low initial coulombic efficiency arising from the…

Despite recent worldwide research efforts, composite silicon-based anodes remain at the centre of debate in the field of lithium-ion batteries. Here, we demonstrated that successful development of composite silicon-based anodes requires the…

Rechargeable lithium ion batteries are integral to today's information-rich, mobile society. Currently they are one of the most popular types of battery used in portable electronics because of their high energy density and flexible design. Despite…

We show that anodes made by depositing thin films of polymer-derived silicon oxycarbide (SiCO) on copper have properties that are comparable to, or better than that of powder-based SiCO anodes. The great advantage of the thin film architecture is…

Composites comprising silicon (Si), graphite (C) and polyacrylonitrile-based disordered carbon (PAN-C), denoted as Si/C/PAN-C, have been synthesized by thermal treatment of mechanically milled silicon, graphite, and polyacrylonitrile (PAN) powder of…
