"For 5,000 cycles (minimum required for a plug-in hybrid vehicle), the remaining active Li would be reduced to well under 1% of the amount of Li present in the cathode initially" nice joke. leaf and volt batteries are rated 1000 to 1500 cycles.
This article reads like a single professor's biography, not an overview of a field of research. Hithisishal ( talk) 21:06, 7 June 2011 (UTC)
On this point: It should be noted that this professor did not invent the nanowire battery. The 3D battery design (including nanowires) was proposed three years before this work was published. The cited example only uses a silicon anode. Without an intercalation of the anode and cathode, greatly increased power density is not possible because the diffusion of lithium through organic liquid electrolytes is slow. In order to have a true "nanowire battery", the intercalation architecture is necessary. — Preceding unsigned comment added by 129.82.79.117 ( talk) 22:15, 17 January 2013 (UTC)
Capacitance of usual graphite anode is 372 mA·h/g while capacitance of typical cathode is 100-180 mA·h/g. It means that main limitation of Li-ion battery is its cathode,not anode.There seem to be no sense to increase capacity of anode if there is no corresponding improvement in its cathode.It will not be able to increase energy density.Possibly, no more than just a few percents. —Preceding unsigned comment added by Stanley( talk) 13:35, 21 January 2011 (UTC)

In this article, the writer in regard to a half-cell version of the silicone nanowire battery, makes the comment: 'However .... would have no commercial value'.I'd like clarification on this. Is he saying that, because [1] It would be too expensive to make, or [2] It would last so long ( i.e. be too good) so that the manufacturers wouldn't make repeat sales of them ? — Preceding unsigned comment added by 165.228.183.228 ( talk) 02:10, 16 May 2012 (UTC)
This electrochemical cell is a so-called half cell consisting of Si nanowires on the positive pole (also termed cathode, place of reduction during discharge) and bulk Li at the negative pole (called anode, place of oxidation during discharge). Moreover, the concept of using nanowires as an electrode material doesn't provide any meaningful storage capacity, energy density or power density in an hypothetical storage device due to the large void density of nanowires. If one would term every research material system he is investigating a "battery", we would fill up pages after pages about what are actually new anode or new cathode systems. This work has been published in a high ranking journal (=famous but not necessarily of much scientific interest...), got attention but has no battery deliverable value. — Preceding unsigned comment added by 188.121.230.34 ( talk) 02:54, 6 July 2012 (UTC)
