LITHIUM TRANSITION METAL-BASED COMPOUND POWDER FOR POSITIVE ELECTRODE MATERIAL IN LITHIUM RECHARGEABLE BATTERY, METHOD FOR MANUFACTURING THE POWDER, SPRAY DRIED PRODUCT OF THE POWDER, FIRING PRECURSOR OF THE POWDER, AND POSITIVE ELECTRODE FOR LITHIUM RECHARGEABLE BATTERY AND LITHIUM RECHARGEABLE BATTERY USING THE POWDER |
摘要 |
This invention provides a lithium transition metal-based compound powder for a positive electrode material in a lithium rechargeable battery, which, when used as a positive material for a lithium rechargeable battery, can simultaneously realize cost reduction, resistance to high voltage, high safety, and battery performance improvement. The lithium transition metal-based compound powder for a positive electrode material in a lithium rechargeable battery is characterized in that, in a mercury penetration curve obtained by a mercury penetration method, the mercury penetration level in a pressure rise from 3.86 kPa to 413 MPa is not less than 0.8 cm3/g and not more than 3 cm3/g. ® KIPO & WIPO 2009 |
