Localized Ru-induced interfacial electronic reconstruction enables highly reversible Li-CO2 batteries
Localized Ru-induced interfacial electronic reconstruction enables highly reversible Li-CO2 batteries
研究概述
通过ZIF-67衍生限域结构,在Co纳米颗粒中局域引入适量Ru,调节界面电子环境并促进Li2CO3形成/分解。Ru15Co85正极锂–CO2电池电压差1.11 V、库仑效率99.7%,稳定循环750次、约3100小时。计算显示适度Ru掺入将Li2CO3解离能垒降至0.65 eV。
