| 1 | 空心炭球在室温钠硫电池中的研究进展显示文摘室温钠硫(RT-Na/S)电池具有理论比容量高(1675 mAh/g)、能量密度大(1276 Wh/kg)以及钠、硫储量丰富且成本低等优势,在智能电网等大规模储能领域具有广阔的应用前景。然而,RT-Na/S电池仍然面临着诸多问题如硫导电性差、放电过程中体积膨胀以及中间态多硫化钠溶解穿梭等,严重地阻碍了电池性能的发挥和实际应用。近年来,空心炭球由于其独特的物理化学性质,在一定程度上能有效地解决硫正极中特别是多硫化钠的溶解穿梭等问题,有效提高了电池的性能。本文介绍了近年来空心炭球基材料的构筑及其在RT-Na/S电池中的应用,重点讨论了孔结构调控、掺杂基团与功能组分修饰对缓解“穿梭效应”及提高电池性能的影响,并对未来的发展进行了展望。 | 杨佳迎 韩浩杰 Hlib Repich 智日成 曲昌镇 孔龙 Stefan Kaskel 王洪强 徐飞 李贺军 | 2020 | 新型炭材料2020，35，6： | 9 |
| 2 | Edge-enriched MoS2 for kinetics-enhanced potassium storage显示文摘Potassium-ion batteries (PIBs) hold great promise as alternatives to lithium ion batteries in post-lithium age, while face challenges of slow reaction kinetics induced by the inherent characteristics of large-size K+. We herein show that creating sufficient exposed edges in MoS2 via constructing ordered mesoporous architecture greatly favors for improved kinetics as well as increased reactive sites for K storage. The engineered MoS2 with edge-enriched planes (EE-MoS2) is featured by three-dimensional bicontinuous frameworks with ordered mesopores of ~ 5.0 nm surrounded by thin wall of ~9.0 nm. Importantly, EE-MoS2 permits exposure of enormous edge planes at pore walls, renders its intrinsic layer spacing more accessible for K^+ and accelerates conversion kinetics, thus realizing enhanced capacity and high rate capability. Impressively, EE-MoS2 displays a high reversible charge capacity of 506 mAh·g^−1 at 0.05 A·g^−1, superior cycling capacities of 321 mAh·g^−1 at 1.0 A·g^−1 after 200 cycles and a capacity of 250 mAh·g^−1 at 2.0 A·g^−1, outperforming edge-deficient MoS2 with nonporous bulk structure. This work enlightens the nanoarchitecture design with abundant edges for improving electrochemical properties and provides a paradigm for exploring high-performance PIBs. | Guangshen Jiang Xiaosa Xu Haojie Han Changzhen Qu Hlib Repich Fei Xu Hongqiang Wang | 2020 | Nano Research2020，13，10： | 3 |
