A series of modified Mn-based lithium intercalation compounds will be synthesized by sol-gel process and characterized using analytical as well as electrochemical techniques. The potential candidate materials will further be evaluated as cathodes for lithium-ion batteries. Cathodes and anodes will be prepared by using a well-established electrodes fabrication technique. The reversible capacity of the modified LiMxMn2-xO4 will be evaluated by developing half-cells with metallic lithium as the counter electrode. Several prismatic design lithium-ion pouch cells will be made with the low temperature electrolyte to examine the feasibility of the proposed concept.
