Title:
ELECTRODE COMPOSITION FOR SECONDARY BATTERY AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2020/059928
Kind Code:
A1
Abstract:
The present invention provides an electrode composition for a secondary battery and, more specifically, provides an electrode composition, which is prepared so as to have a more stable structure by doping potassium into a Prussian white structure. The electrode composition is structurally stable and contains no moisture therein, and thus can have excellent lifetime characteristics.
