Abstract

Read online

Reactive radical intermediates can be a problem leading to fast degradation of organic electrodes in sodium-ion batteries. Here, the authors show a stabilized α-C radical displaying reversible transformations between C=C, α-C radical and α-C anionic states to facilitate long cycling and improved capacity.
