Publication/Patent Number: TW201911630A Publication Date: 2019-03-16 Application Number: 106127536 Filing Date: 2017-08-15 Inventor: Yang chun chen   Chen, Wei-houng   Assignee: MING CHI UNIVERSITY OF TECHNOLOGY   IPC: H01M4/587 Abstract: A process of producing LFS/C composite material uses a sol-gel method or a spray drying method to synthesize LFS/C composite material. More particularly, different carbon sources or carbon materials are used to perform the modification of an encapsulated carbon layer during the synthesis process. Alternatively, oxide is reused to encapsulate a surface of LFS/C composite material to perform the surface modification. By uniformly scattering the carbon source or the conductive carbon material on the surface of LFS active substance, an electron conduction path between particles can be increased, thereby effectively improving and enhancing the conductivity of LFS active substance. Moreover, the prepared LFS/C composite material has an excellent high power property and a good charging/discharging cycle life. Under the condition of carrying high-speed charging/discharging, it has an excellent stability and a specific discharge capacity. It is suitable to be used as a cathode of secondary lithium ion battery.
