摘要：
An LiMn2O4 spinel of a poorly ordered structure is produced by subjecting MnO2 + LOH and MnO2 + LiOH + 5 Wt % Cr2O3 mixtures to plastic deformation at 1-2 GPa and then annealing them at 400degreesC. The size of individual particles is 10-100 nm. Cathodes based on chromium-modified spinels have a higher stability and a longer shelf life.
