Catalytic performance of oxygen vacancies-enriched h-MoO3 in lithium-oxygen batteries
Source abstract
Abstract
The development of lithium-oxygen battery was an effective way to alleviate energy crisis, save energy and protect environment. The design of cathode catalyst with high catalytic performance can effectively promote the performance of lithium-oxygen battery. To research the influence of oxygen vacancies on the electrochemical catalytic performance, a novel and effective method was proposed to introduce more oxygen vacancies into MoO 3. The h-MoO 3 with oxygen-rich vacancies (named MoO 3-HTP) was synthesized by using original MoO 3 to heat together with NaH 2PO 4. As the cathode catalyst of lithium-oxygen batteries, MoO 3-HTP had a smaller first cycle overpotential of 0.76 V and showed 137 stable cycles under a limited capacity of 500 mAh g −1 at 200 mA g −1 from the comparison of the MoO 3 and MoO 3-HT. And MoO 3-HTP-based batteries had the lower overpotential of 1.58 V under the first full charge-discharge curves at 200 mA g −1 and 400 mA g −1. The excellent conductivity and electrocatalytic performance of MoO 3-HTP were put down to the abundance of oxygen vacancies.
