Redox shuttle additives for overcharge protection in lithium batteries

PDF Version Also Available for Download.

Description

Seven new redox shuttle additives with shuttle current onset potentials above 4.2 V vs Li/Li+ are reported, along with diffusion coefficients for the neutral additives. The dependence of the limiting shuttle current on the respective diffusion coefficients of the oxidized and reduced forms of an additive is clarified. Overcharge protection in liquid electrolyte Li/LiMn{sub 2}O{sub 4} cells is demonstrated.
