Title:
POSITIVE ELECTRODE ACTIVE MATERIAL AND HYBRID ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/073400
Kind Code:
A1
Abstract:
The main purpose of the present invention is to provide a positive electrode active material which operates at a high potential and is used in hybrid ion batteries of Li ions and Na ions. The present invention achieves the above-mentioned purpose by providing a positive electrode active material which is used in hybrid ion batteries of Li ions and Na ions, and which is characterized by containing an Na4M3(PO4)2P2O7 crystal phase (wherein M represents at least one element selected from among Ni, Co, Mn, Fe, V, Cr, Cu and Zn.)
