High-capacity and superior behavior of the Ni–Cu co-doped spinel LiMn₂O₄ cathodes rapidly prepared via microwave-induced solution flameless combustion

Abstract

A simple and rapid microwave-induced solution flameless combustion method to prepare high-capacity Ni-Cu co-doped spinel LiMn2O4 is provided in this work. Ni-Cu co-doping effectively reduces the lattice parameters and Jahn-Teller...

Improved electrochemical performance of spinel LiMn2O4 derived from manganese-based metal–organic frameworks by organic ligands

“…1–4 Spinel LiMn 2 O 4 has garnered significant attention due to its high voltage plateau, eco-friendliness, and cost-effectiveness. 5–7 However, several issues with spinel LiMn 2 O 4 severely hinder its large-scale application. The Mn 3+ ion in the material, acting as an active substance, undergoes the following reaction during the cycle: 2Mn 3+ → Mn 4+ (solid) + Mn 2+ (liquid), leading to the loss of Mn 3+ ions.…”
