“Nano structured Mn-Based Silicate: Cathode Material for High Energy/Power Density Li-ion batteries."

In this project our aim is to synthesizes pure phase Li2MnSiO4 and investigating its performance as a cathode material in Li-ion battery. Li2MnSiO4 may be considered as a suitable electrode material over others available battery type Li-electrode due to the existence of 2 moles of Li per formula unit, and abundant with ecofriendly nature of Si and Mn, further signifies its importance as electrode materials. However, pure phase formation of Li2MnSiO4 is still challenging due to its various crystal structures.
