Ruthenium nanocrystals as cathode catalysts for lithium-oxygen batteries with a superior performance
The key factor to improve the electrochemical performance of Li-O₂ batteries is to find effective cathode catalysts to promote the oxygen reduction and oxygen evolution reactions. Herein, we report the synthesis of an effective cathode catalyst of ruthenium nanocrystals supported on carbon black substrate by a surfactant assisting method. The as-prepared ruthenium nanocrystals exhibited an exce...
متن کاملNanostructured carbon-based cathode catalysts for nonaqueous lithium-oxygen batteries.
Although lithium-ion batteries are traditionally considered to be the most promising candidate for electrochemical energy storage owing to their relatively long cycle life and high energy efficiency, their limited energy density as well as high cost are still causing a bottleneck for their long-term applications. Alternatively, rechargeable Li-O2 batteries have the potential to practically prov...
متن کاملRuthenium nanocrystal decorated vertical graphene nanosheets@Ni foam as highly efficient cathode catalysts for lithium-oxygen batteries
The electrochemical performance of lithium-oxygen (Li-O2) batteries can be markedly improved through designing the architecture of cathode electrodes with sufficient spaces to facilitate the diffusion of oxygen and accommodate the discharge products, and optimizing the cathode catalyst to promote the oxygen reduction reaction and oxygen evolution reaction (OER). Herein, we report the synthesis ...
متن کاملMesoporous LiFePO4/C nanocomposite cathode materials for high power lithium ion batteries with superior performance.
Today, we are facing a severe challenge–global warming and climate change due to the burning of fossil fuels for energy. The greenhouse gas emissions are mainly derived from the transportation sector and electricity power generation. Therefore, a global solution must involve a dramatic move to renewable energy. [ 1 , 2 ] Lithium ion batteries have proved themselves the most advanced electrochem...
متن کاملNitrate-Melt Synthesized HT-LiCoO2 as a Superior Cathode-Material for Lithium-Ion Batteries
An electrochemically-active high-temperature form of LiCoO2 (HT-LiCoO2) is prepared by thermally decomposing its constituent metal-nitrates at 700 oC. The synthetic conditions have been optimized to achieve improved performance with the HT-LiCoO2 cathode in Li-ion batteries. For this purpose, the synthesized materials have been characterized by powder X-ray diffraction, scanning electron micros...
