Dual-functional 3D carbon fibers decorated with Co nanoparticles and Co-N_x sites for rechargeable aprotic Li–O₂ batteries

Abstract

Aprotic Li-O2 battery possesses extremely high theoretical energy density among all existing rechargeable battery systems. Thus, it has been believed as one of the most potential next-generation energy storage devices....

Anchoring NiO Nanosheet on the Surface of CNT to Enhance the Performance of a Li-O2 Battery

“…Carbon materials, considered as common electrode materials, possess excellent properties, including environmental friendliness, brilliant electrical conductivity and a high surface area, which have been paid a lot of attention. In Li-O 2 batteries, carbon materials exhibit prominent catalytic performance as electrocatalysts owing to the complex porous structure [26,27]. They are usually considered as important carriers in cathode catalysts [28][29][30][31][32].…”

Incorporated O-CoP nanosheets with an O–P interpenetrated interface as electrocatalytic cathodes for rechargeable Li–CO2batteries

“…Accordingly, metal–gas batteries, metal–S batteries, and other high energy density energy storage devices have become a hot topic in current research and demonstrate great potential to promote revolutionary advances in energy storage devices. 11–19…”

“…Accordingly, metal-gas batteries, metal-S batteries, and other high energy density energy storage devices have become a hot topic in current research and demonstrate great potential to promote revolutionary advances in energy storage devices. [11][12][13][14][15][16][17][18][19] Li-CO 2 batteries, as an emerging energy storage device, are in the spotlight for advantages featuring environmental friendliness, high energy density (1876 W h kg À1 ), and high fixation capacity of CO 2 since its introduction. 5,6,[20][21][22][23] Li-CO 2 batteries provide a two-pronged solution for simultaneously addressing the environmental and energy storage issues.…”
