Abstract

• Sonochemical method is used to prepare high voltage spinel LiNi0.5Mn1.5O4. • Sonochemistry has been proven to be green and cost-effective method. • The ICP results of the molar ratios of Li:Ni:Mn are close to 2:1:3. • LiNi0.5Mn1.5O4 is a promising cathode material for high voltage Li-ion batteries. • Addition of glucose helps to enhance crystallinity and electrochemical activity.
