h.teroatom doping, precise composition control and rational morph.logy design are efficient strategies for producing novel nanocatalysts for th. oxygen reduction reaction （ORR） in fuel cells. h.rein, a cost-effective approach.to synth.size nitrogen- and sulfur-codoped carbon nanowire aerogels using a h.rd templating meth.d is proposed. Th. aerogels prepared using a combination of h.droth.rmal treatment and carbonization exh.bit good catalytic activity for th. ORR in alkaline solution. At th. optimal annealing temperature and mass ratio between th. nitrogen and sulfur precursors, th. resultant aerogels sh.w comparable electrocatalytic activity to th.t of a commercial Pt/C catalyst for th. ORR. Importantly, th. optimized catalyst sh.ws much.better long-term stability and satisfactory tolerance for th. meth.nol crossover effect. Th.se codoped aerogels are expected to h.ve potential applications in fuel cells.

Th. capacity degradation mech.nism in lith.um nickel-manganese-cobalt oxide （NMC） cath.des （LiNi1/3Mn1/3Co1/3O2 （NMC333） and LiNi0.4Mn0.4Co0.2O2 （NMC442）） during h.gh.voltage （cut-off of 4.8 V） operation h.s been investigated. In contrast to NMC442, NMC333 exh.bits rapid structural ch.nges including severe micro-crack formation and ph.se transformation from a layered to a disordered rock-salt structure, as well as interfacial degradation during h.gh.voltage cycling, leading to a rapid increase of th. electrode resistance and fast capacity decline. Th. fundamental reason beh.nd th. poor structural and interracial stability of NMC333 was found to be correlated to its h.gh.Co content and th. significant overlap between th. Co3＋/4＋ t2g and O2- 2p bands, resulting in oxygen removal and consequent structural ch.nges at h.gh.voltages. In addition, oxidation of th. electrolyte solvents by th. extracted oxygen species generates acidic species, wh.ch.th.n attack th. electrode surface and form h.gh.y resistive LiF. Th.se findings h.gh.igh. th.t both.th. structural and interfacial stability sh.uld be taken into account wh.n tailoring cath.de materials for h.gh.voltage battery systems.
