Combustion-assisted synthesis of Mn-rich cathode for high performance Li-ion batteries

The present decade of research is making significant efforts to develop lithium battery technology with stable cycling, high capacity, and affordability. Mn-rich layered materials are likely to fall within this research pace as an effective alternative. However, the life expectancy of Mn-rich layered materials are unpredictably short which impedes its commercial applicability. Herein, we demonstrate the synthesis of Li [Li0.1Ni0.3Mn0.7]O2 by coprecipitation
method followed by rapid combustion with organic fuels at various temperatures. Physical characterizations were performed to confirm the structure and surface morphology of
Li [Li0.1Ni0.3Mn0.7]O2. The fine-tuned cathode material established stable cycling even at high voltage (4.8V) with the capacity retention of 98.2% upto 100 cycles. The maximum
electrochemical rate capabilities at 0.1C, 0.2C, 0.5C, 1C, 2C and 5C are 325 , 314 , 259, 228, 173 and 109 mAh g-1 respectively. Thus, Mn- rich cathodes in lithium-based batteries provides a pathway to facilitate practical feasibility, boost cycling stability, attain high-capacity with lower expense.
