Hyper-conjugated lithium carboxylate based on a perylene unit for high-rate organic lithium-ion batteries

Abstract

A high-rate cycling lithium carboxylate-based organic anode material using perylene core as a platform for stabilization is described. The hyper-conjugated core unit of perylene associated with lithium carboxylate confers the electrode an outstanding rate capability without any electrode formulation engineering, maintaining over 120 mA h g⁻¹ gravimetric capacity after one hundred cycles at 5 Li⁺/1 h rate.
