Preparation pseudo four components Li-Ni-Co-Ti oxides by electrostatic spray deposition method and its charge-discharge property

Abstract

Layered-type pseudo four components Li-Ni-Co-Ti oxides library was prepared by electrostatic spray deposition method (ESD). Charge - discharge property of heat-treated library was evaluated by combinatorial high-throughput characterization system. Fine particles obtained by ESD showed large capacity and plateau voltage compared with solid state reaction. Charge-discharge capacity increased as Ni component was increasing and decreased as Ti component was increasing. Furthermore, the candidate cathode material for Li-ion secondary battery was found in newly composition condition.
