最新的Li-O2电池报道,Science,虽然是Bruce的 附件1:A Reversible and Higher-Rate Li-O2Battery The rechargeable non-aqueous Li-O2 battery is receiving a great deal of interest because theoretically its specific energy far exceeds the best that can be achieved with lithium-ion cells. Operation of the rechargeable Li-O2 battery depends critically on repeated and highly reversible formation/decomposition of Li2O2 at the cathode on cycling. Here we show that this is possible, using a dimethyl sulfoxide electrolyte and porous gold electrode (95% capacity retention from cycles 1-100), whereas previously only partial Li2O2 formation/decomposition occurred and with limited cycling. Furthermore, we present data indicating that the kinetics of Li2O2 oxidation on charge is approximately 10-fold faster than on carbon electrodes. 附件2:A Reversible and Higher-Rate Li-O2 Battery This PDF file includes: Materials and Methods Figs.
