<P>A lithium–iodine (Li–I<SUB>2</SUB>) cell using the triiodide/iodide (I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP>) redox couple in an aqueous cathode has superior gravimetric and volumetric energy densities (∼ 330 W h kg<SUP>–1</SUP> and ∼650 W h L<SUP>–1</SUP>, respectively, from saturated I<SUB>2</SUB> in an aqueous cathode) to the reported aqueous Li-ion batteries and aqueous cathode-type batteries, which provides an opportunity to construct cost-effective and high-performance energy storage. To apply this I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP> aqueous cathode for a portable and compact 3.5 V battery, unlike for grid-scale storage as general target of redox flow batteries, we use a three-dimensional and millimeter thick carbon nanotube current collector for the I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP> redox reaction, which can shorten the diffusion length of the redox couple and provide rapid electron transport. These endeavors allow the Li–I<SUB>2</SUB> battery to enlarge its specific capacity, cycling retention, and maintain a stable potential, thereby demonstrating a promising candidate for an environmentally benign and reusable portable battery.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2014/nalefd.2014.14.issue-2/nl404784d/production/images/medium/nl-2013-04784d_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl404784d'>ACS Electronic Supporting Info</A></P>

<P>The development of active water oxidation catalysts is critical to achieve high efficiency in overall water splitting. Recently, sub 10 nm-sized monodispersed partially oxidized manganese oxide nanoparticles were shown to exhibit not only superior catalytic performance for oxygen evolution, but also unique electrokinetics, as compared to their bulk counterparts. In the present work, the water oxidizing mechanism of partially oxidized MnO nanoparticles was investigated using integrated in situ spectroscopic and electrokinetic analyses. We successfully demonstrated that, in contrast to previously reported manganese (Mn)-based catalysts, Mn(III) species are stably generated on the, surface of MnO nanoparticles via a proton-coupled electron transfer pathway. Furthermore, we confirmed as to MnO nanoparticles that the one-electron oxidation step from Mn(II) to Mn(III) is no longer the rate-determining step for water oxidation and that Mn(W)=O species are generated as reaction intermediates during catalysis.</P>
