dc.description.abstract | High energy and power density lithium ion batteries (LIB) are extensively being studied for their potential applications in portable electronics and hybrid/full electric vehicles as well as for their ability to store solar, wind and other renewable energies with high efficiency [1]. LiNi 0.5 Mn 1.5 O 4 (LNMO) attracts attention as a high voltage cathode material (4.7 V vs. Li/Li +) with good capacity (147 mAh/g); having potential for high power applications [2]. However, cyclic stability of LNMO still remains an issue since all cathode materials containing Mn are challenged with capacity fade problem due to Mn leaching within commercial electrolytes [1]. Introducing a shell layer on LNMO that is stable at high voltages can prevent Mn dissolution and increase cycle life; while also enabling good conductivity, if ionically and electronically conductive [3]. Materials such as Li 4 Ti 5 O 12 [4] , Li 2 TiO 3 [5] and TiO 2 [4] attract attention as shell material candidates in literature, owing to their structural stability within organic electrolytes at high voltages, as well as their 3D Li + diffusion paths allowing good ionic conductivity. TiO 2 is used as the surface modification material in this work; synthesized using a sol-gel approach. Different from previous studies; effect of different annealing temperatures (500 to 850 o C) on Ti 4+ diffusion from surface towards the core of LNMO is investigated. Electrochemical performances are compared while also considering the ordering/disordering changes within the LNMO crystal structure. | - |
