<P>A novel lithium-ion/oxygen battery employing Pyr<SUB>14</SUB>TFSI-LiTFSI as the electrolyte and nanostructured Li<SUB><I>x</I></SUB>Sn–C as the anode is reported. The remarkable energy content of the oxygen cathode, the replacement of the lithium metal anode by a nanostructured stable lithium-alloying composite, and the concomitant use of nonflammable ionic liquid-based electrolyte result in a new and intrinsically safer energy storage system. The lithium-ion/oxygen battery delivers a stable capacity of 500 mAh g<SUP>–1</SUP> at a working voltage of 2.4 V with a low charge–discharge polarization. However, further characterization of this new system by electrochemical impedance spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy reveals the progressive decrease of the battery working voltage, because of the crossover of oxygen through the electrolyte and its direct reaction with the Li<SUB><I>x</I></SUB>Sn–C anode.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2015/aamick.2015.7.issue-40/acsami.5b07414/production/images/medium/am-2015-07414p_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am5b07414'>ACS Electronic Supporting Info</A></P>

Sports Sponsorship is considered to be one of the most effective tools in marketing. However, in order to assess the effectiveness of sponsoring activities in customer’s mind, science and business practice often refer to explicit measures such as self-reports or focus interviews. Such aligned conventional measurement approach is missing mental processes which run without awareness, so-called implicit processes, taking place and activity hidden in the unconscious mind. Against that background, the goal of the current work is to shed further light on the impact of athlete sponsorship on dual processes underlying customer’s associations toward a brand.
