dc.description.abstractManganese-based cathode materials are good alternatives to nickel-based layered cathodes in lithium-ion batteries due to the much cheaper cost of manganese ores. Coprecipitation is a popular method to produce precursor materials for lithium-ion batteries since its versatility enables the synthesis of a wide range of compositions with various architectures. In this study, spherical 2-mu m to 4-mu m-diameter binary Mn0.8Ni0.2CO3 and ternary Mn4/6Ni1/6Co1/6CO3 precursor materials were synthesized by tuning synthesis conditions including temperature, feeding mode and reagent quantity. The binary and ternary precursor materials were mixed and reacted with Li2CO3 at 800 degrees C to obtain LiMn1.6Ni0.4O4 and Li1.2Mn0.54Ni0.13Co0.13O2 cathode materials, respectively. LiMn1.6Ni0.4O4 had a discharge capacity of 132 mAh g(-1) and exhibited excellent cycle life and voltage retention. On the other hand, 221 mAh g(-1) discharge capacity was achieved with Li1.2Mn0.54Ni0.13Co0.13O2 , but it showed a fast capacity and voltage decay. A hybrid electrode made of 50:50 wt% of both cathodes yielded 166 mAh g(-1) capacity and 3.95 V average discharge voltage with much reduced voltage decay and capacity fading rate, thereby mitigating each other's weakness in the process.
