The substitution of Co for Fe in Pnma-Li2FePO4F i.e. Li2Fe1−xCoxPO4F (x = 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8) are stable enough as new cathode materials and with the concentration of Co increases the discharge potential of the materials can increase.

Calculated Average

Current commercially available rechargeable Li-ion batteries, for example LiCoO2, are working mostly in the 4 V regime. One often suggested possibility to improve the effectivity of Li-ion batteries are the creation of the 5 V cathode materials. We performed quantum mechanical calculations on the average battery voltage for the Li2Co[Formula: see text]Mn[Formula: see text]O8 (x = 0, 1, 2, 3 and 4) cathode materials by means of the WIEN2k computer program package. The calculated average battery voltages for x = 0, 1, 2, 3 and 4 are equal to 3.95, 5, 4.47, 4.19 and 3.99 V. Our ab initio calculation results are compared with the available experimental data for x = 0, 1, 2 and 4 which are equal to 4, 5, 5 and 4 V. Thereby, for the Li2Co1Mn3O8 battery cathode material, our calculated average battery voltage around 5 V is in perfect agreement with the experimentally available battery voltage value of 5 Volt. Nevertheless, our calculated average battery voltage is underestimated (4.47 V) for the Li2Co2Mn2O8 cathode material, which also experimentally exhibits the 5 V voltage.
