TW201933666A
Method for preparing porous composite material used in anode of lithium-ion battery which is beneficial to the application of power storage and power supply equipment such as long-term and stable electronic products and transportation
Publication/Patent Number: TW201933666A Publication Date: 2019-08-16 Application Number: 107101528 Filing Date: 2018-01-16 Inventor: Yang, Chun-cheng   Wu, Yi-xuan   Wu, Zong-han   Yang min yan   Assignee: MING CHI UNIVERSITY OF TECHNOLOGY   IPC: H01M10/052 Abstract: A method for preparing porous composite material used in anode of lithium-ion battery comprises the steps of (a) self-assembling a mixture and dispersing it in a solvent so as to obtain a first dispersion liquid containing silicon/carbon composite material, wherein the mixture comprises a silicon-containing nanometer particle, graphene oxide, a cationic surfactant and a carbon-containing precursor; (b) grinding the first dispersion liquid to obtain a second dispersion liquid; (c) mixing a carbon-containing nanosphere and the second dispersion liquid to obtain a mixed liquid; (d) spray drying the mixed liquid to obtain a composite microsphere; and (e) sintering the composite microsphere in the presence of a reducing gas. The porous composite material prepared by the method helps to provide a high specific capacity for lithium-ion battery, better long-term charging/discharging stability and higher electronic conductivity so as to be applied in anode of lithium-ion battery.
