Redox shuttle for overcharge protection
Web1. dec 2006 · Redox shuttle is a promising mechanism for intrinsic overcharge protection in lithium-ion cells and batteries. Two lithium borate cluster salts are reported to function as both the main salt for a… Expand 35 An extremely durable redox shuttle additive for overcharge protection of lithium-ion batteries Jingjing Zhang, I. Shkrob, +7 authors Lu … WebOvercharge can be combated using redox shuttles, which act as an internal shunt to prevent electrolyte oxidation by oxidizing themselves. Instability of the oxidized form, usually a radical cation, limits redox shuttle lifetimes and thus the number of overcharge cycles that can be maintained before failure to stabilize (limit) cell voltage.
