Binuclear Cu complex catalysis enabling Li-CO₂ battery with a high discharge voltage above 3.0 V.

ABSTRACT: Li-CO₂ batteries possess exceptional advantages in using greenhouse gases to provide electrical energy. However, these batteries following Li₂CO₃-product route usually deliver low output voltage (<2.5 V) and energy efficiency. Besides, Li₂CO₃-related parasitic reactions can further degrade battery performance. Herein, we introduce a soluble binuclear copper(I) complex as the liquid catalyst to achieve Li₂C₂O₄ products in Li-CO₂ batteries. The Li-CO₂ battery using the copper(I) complex exhibits a high electromotive voltage up to 3.38 V, an increased output voltage of 3.04 V, and an enlarged discharge capacity of 5846 mAh g^-1. And it shows robust cyclability over 400 cycle
