Abstract 

The speaker will discuss new materials that were developed to improve the conductivity of cathodes in lithium-ion batteries.

(1) A novel silver-based material [Ag7Fe3(P2O7)4], synthesized by means of a solid-state technique, starts out with a high ionic conductivity and forms a conductive Ag metal network upon initial discharge, which enhances conductivity.

(2) The first reduction and oxidation process of zinc ferrite (ZnFe2O4), synthesized by initial co-precipitation followed by a hydrothermal reaction, was analyzed.

(3) The electrochemical performance of three forms of Li4Ti5O12 (3D, Ca-doped, and multiwalled carbon nanotube composite samples) was investigated. The 3D sample delivered three times the capacity (at 100°C) of commercial spherical cathode material.
