Ultrahigh Energy Density Li-Organic Primary Batteries

[摘要] Organic electrode materials are promising candidates for battery electrode materials due to the abundant resource, structural diversity, environmental friendliness, and potential low cost.[1] However, most ofreported organic materials rely on one-electron redox reaction peractive group.[2] For example, carbonyl group (C=O) transforms intoC–O–Li by accepting one electron. This severely limits the specificcapacities and energy densities, which are much lower than their inorganic counterparts for primary lithium batteries, such as CFx, SO2,SOCl2, and SF6. Therefore, new organic electrode materials that enablemulti-electron reaction per active group need to be developed to meetthe demand of high energy density.
