Abstract
En 中文
Despite the ubiquitousness of lithium-ion intercalation batteries, there are still many open questions about the relationship between ion and electron transfer. Zhang et al. present a combined experimental and modeling study examining the fundamental mechanisms of lithium-ion intercalation into battery cathodes by analyzing current-voltage responses at small overpotentials (see the Perspective by Warburton). A key finding was the close agreement between the experiments and coupled ion–electron transfer theory rate expressions. The authors concluded that the reaction-limited current in lithium-ion batteries is associated with the lithium-ion vacancy fraction, in conjunction with temperature and electrolyte effects, thus providing a pathway for designing lithium-ion battery interfaces. —Marc S.
