N, O-diatomic dopants activate catalytic activity of 3D self-standing graphene carbon aerogel for long-cycle and high-efficiency Li-CO2 batteries

A Li–O2/CO2 battery based on bio-inspired engineering of the Bi2S3/PVP cathode

“…A Li–CO 2 battery, as an emerging technology, takes greenhouse gas CO 2 as the cathode and theoretically has a high specific energy density of 1876 W h kg −1 , which has the potential to provide a high specific energy density power source while effectively utilizing greenhouse gas CO 2 , providing hope for solving the current energy crisis and climate warming. 16–20 However, the charging process of rechargeable Li–CO 2 batteries involves the electrochemical oxidative decomposition of Li 2 CO 3 or the reversible reaction between Li 2 CO 3 and carbon species to generate CO 2 gas molecules and Li + ions, which largely depends on the choice of different catalysts. On the one hand, nonpolar CO 2 molecules of carbon–oxygen double bond rupture makes the dynamics of the electrochemical reduction of CO 2 a slow process.…”

Recent Progress in Multifunctional Graphene-Based Nanocomposites for Photocatalysis and Electrocatalysis Application

“…Based on this hybridization, the carbon atoms connected by graphene “sp 2 ” hybridization can be tightly stacked into a single-layer two-dimensional honeycomb lattice structure, with a high specific surface area and good electronic properties [ 36 ]. At the same time, the unique band structure also makes graphene have good conductivity and electron mobility [ 37 ]. Graphene has a variety of application characteristics.…”
