RESEARCHJanuary 26, 2009Nano tin electrodes beat graphiteShape tin oxide into the right nanostructures and you have inexpensive, high-capacity electrodes for lithium-ion batteries.Tin oxide nanowires studded with clumps of tin atoms and flower-like tin oxide nanostructures -- the results of separate research efforts -- have more than twice the capacity of graphite when used as anodes in lithium-ion batteries. Nanostructured tin oxide electrodes could be used in high-capacity lithium-ion batteries that power vehicles and store electricity generated by renewable sources.
