今天是一篇关于Li-CO2电池正极材料的文章。文章在石墨烯的碳骨架中引入了拓扑缺陷。将得到的材料(TDG-1000)用作Li-CO2电池的正极,测试其电化学性能,发现TDG-1000基Li-CO2电池表现出最好的性能,在0.5A g−1的电流密度下,其满放电容量达到69.000 mA h g−1以上,即使在2.0A g−1的高电流密度下(低过电位1.87V),也具有优异的倍率性能。在1.0 A g−1电流密度下具有长期稳定性(长达600次),比容量为500 mA g−1。密度泛函理论计算表明,拓扑缺陷中带负电荷的C原子可作为二氧化碳分子的吸附和活化中心,杂环五角环(C5)具有较小的理论充放电电位差1.01V,表明该催化剂对二氧化碳还原和Li2CO3分解具有良好的催化活性。

Cheng Yi, Zeng Shunxi, Xiao Shunyao, Chen Turin, the Lotus Tower finished the stills! Please hurry up later, want to see!
The play is adapted from rattan ping's novel "propitious grain lotus floor", tells the story of the famous wulin said doors main Li Xiangyi severely wounded in a war, since then retire jianghu LangZhongLi lotus become indifferent to fame and wealth, to meet a new/sick and old enemy flute sound fly again in river's lake, three people fighting hand in hand, altogether broken mystery story.

【国家卫健委:10月28日新增本土确诊病例324例】La partie continentale de la Chine a signalé vendredi 324 cas confirmés de #COVID19# transmis localement, a indiqué samedi la Commission nationale de la santé. Un total de 1.153 porteurs asymptomatiques locaux ont été nouvellement identifiés. En tout, 234 patients atteints de la COVID-19 sont sortis de l'hôpital après leur guérison vendredi, portant à 250.010 le nombre total des patients guéris de la COVID-19. Vendredi, aucun nouveau décès lié à la COVID-19 n'a été enregistré, le bilan total restant à 5.226 morts.
