Abstract
A dramatic improvement in the elevated temperature performance of spinel phase LiNi0.5Mn1.5O4 cathode is achieved by surface modification with LiFePO4. Presence of strong covalent P-O bond in the olivine phase translates necessary thermal stability to LiNi0.5Mn1.5O4 cathode and renders â¼89% of initial reversible capacity after 50 cycles at 55 °C. Though the LiFePO4 modified phase exhibits marginal reduction in the initial reversibility than bare LiNi0.5Mn1.5O4, displayed exceptional capacity retention characteristics irrespective of either ambient or elevated temperature.
