EP3770996A1
METHOD FOR MANUFACTURING LITHIUM IRON PHOSPHATE/CARBON COMPOSITE CATHODE MATERIAL FOR SECONDARY LITHIUM ION BATTERY
Publication/Patent Number: EP3770996A1 Publication Date: 2021-01-27 Application Number: 19187933.7 Filing Date: 2019-07-23 Inventor: Wang, Ruey-yu   Chen, Seiko   Yang, Chun-chen   Pien, Chieh-yi   Assignee: Formosa Plastics Transport Corporation   IPC: H01M4/04 Abstract: A method for manufacturing a lithium iron phosphate/carbon composite cathode material for a secondary lithium ion battery includes the steps of preparing a mixture solution which includes a lithium source, an iron source, a phosphate source, and a carbon precursor combination in a liquid medium; subjecting the mixture solution to a spray drying treatment to obtain a particulate powdery material; and sintering the particulate powdery material. The carbon precursor combination includes a porous graphene oxide-based additive and a first carbon precursor, which is different from the porous graphene oxide-based additive.

TWI671264B
Process for producing spinel-lnmo material and use the same
Publication/Patent Number: TWI671264B Publication Date: 2019-09-11 Application Number: 106114702 Filing Date: 2017-05-03 Inventor: Wang, Ruey Yu   Yang, Chun Chen   Wu, Zong Han   You, Cheng En   Li, Jun Rui   Assignee: FORMOSA PLASTICS TRANSPORT CORPORATION   IPC: H01M10/0525 Abstract: A process for producing hight voltage LiNi0.5Mn1.5O4 (spinel-LNMO) cathode material is disclosed by a solid-state method or a spray dry method, particularly to have the spinel-LNMO modified in advace in the course of synthesizing process; resulted in that the spinel-LNMO cathode material can not only significantly improve conductivity of the active materials of spinel-LNMO, but also markedly solve the low electronic conductivity problem of the spinel-LNMO material, as well as improve the obtained spinel-LNMO cathode material exhibited excellent in high power characteristics and having very good cycling charge/discharge performances, and suited for making as a secondary lithium ion battery cathode.
