| 1 | Matryoshka-type carbon-stabilized hollow Si spheres as an advanced anode material for lithium-ion batteries显示文摘Silicon(Si)is regarded as the potential anode for lithium-ion batteries(LIBs),due to the remarkable theoretical specific capacity and low voltage plateau.However,the rapid capacity decay resulting from volume variation and slow electron/ion transportation of Si limit its practical application.Here,matryoshka-type carbon-stabilized hollow silicon spheres(Si/C/Si/C)are synthesized by an aluminothermic reduction and calcination process.The Si/C/Si/C anode materials prepared at 500℃(Si/C/Si/C-500)exhibit unique structures,in which amorphous region and porous structure are preserved in the Si layers.The anode based on Si/C/Si/C-500 displays an initial specific capacity of 2792 m Ah/g at a current density of 100 m A/g.At 1000 m A/g,this anode retains a reversible capacity of 1673 m Ah/g,86.9%of the initial capacity after 200 cycles.Such synthetic strategy can be employed to fabricate other high-capacity anode materials with large volume variation during charge/discharge process. | Huimin Wu Peibo Gao Jinglin Mu Zhichao Miao Pengfei Zhou Tong Zhou Jin Zhou | 2022 | Chinese Chemical Letters2022，33，6： | 1 |
| 2 | Heterogeneous isomorphism hollow SiGe nanospheres with porous carbon reinforcing for superior electrochemical lithium storage显示文摘Silicon is emerging as a promising next-generation lithium-ion battery anode because of its high theoretical capacity and low cost.However,the poor cyclability and inferior rate performance hinder its largescale applications.Here,hollow silicon/germanium(H-SiGe)nanospheres with a binary-active component and heterogeneous structure combined with porous carbon(pC)reinforcing are synthesized as lithium-ion battery anodes.Experimental studies demonstrate that the H-SiGe/pC anodes possess tiny volume expansion,high ion/electron conductivity,and stable electrode interface.Theoretical calculations confirm that through the replacement of Si using Ge with rational component control,the diffusion energy barrier of lithium will be reduced and lithium storage ability can be improved because of the slight charge polarization.Benefiting from these unique merits,the H-SiGe/pC anodes display a high initial specific capacity of 2922.2 mA h g^(-1)at 0.1 A g^(-1),superior rate capability(59.4%capacity retention from 0.5 to 8 A g^(-1)),and excellent cycling stability(81%retention after 700 cycles at 5 A g^(-1)at 1.0–1.2 mg cm^(-2)).An outstanding stability is preserved even at a high loading of 3.2 mg cm^(-2)with an improved reversible capacity of 429.1 mA h g^(-1)after 500 cycles at 4 A g^(-1).Furthermore,the full-cell with the prelithiated H-SiGe/pC anode and LiFePO4cathode exhibits an impressive capacity performance. | Peibo Gao Huimin Wu Wenhao Liu Shuang Tian Jinglin Mu Zhichao Miao Pengfei Zhou Huanian Zhang Tong Zhou Jin Zhou | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
