In this work, we describe for the first time a high-energy and transparent thin film electrode made from nanosized LiFeO2 grown on an indium tin oxide (ITO) substrate and in situ mixed with submicronic grains of Ag homogeneously distributed to improve the conductivity. An accurate description of its texture and structure was accomplished by combining various techniques such as XPS, SEM, TEM, EDX and AFM. The electrode has the ability to deliver capacity values above 160 Ah kg(-1) upon extensive cycling with capacity retention near to 98%, an average voltage of 3.0 V vs. Li+/Li and a specific energy close to 410 W h kg(-1) as a result.
