COMPOSITE PARTICLES FOR ANODE ACTIVE MATERIAL AND ANODE FOR ALL-SOLID-STATE BATTERY COMPRISING SAME

Title:

COMPOSITE PARTICLES FOR ANODE ACTIVE MATERIAL AND ANODE FOR ALL-SOLID-STATE BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2019/226020

Kind Code:

A1

Abstract:

Composite particles which are anode active materials, according to the present invention, sufficiently secure electrochemical reaction sites of solid electrolytes and electrode active materials, and thus, problems of capacity reduction and output reduction do not occur. The composite particles according to the present invention are filled with a conductive material comprising solid electrolytes and a conductive material inside shape-adjusted carbon particles through spheroidization of carbon materials such as flake graphite, and thus, the contact area between the active material and the solid electrolyte is increased, and the paths of ion conduction and electron conduction are extended and maintained to the inside of the active material particles.
