Lithium Ion Cathode Materials Prepared Using Glycerol as Solvent and Reactant
- University of Missouri
Two different types of cathode materials were prepared using glycerol as a solvent and reactant. The LiMn1/3Ni1/3Co1/3O2 layered oxide cathode material was successfully synthesized with a shorter time of heat treatment of 8hr at 900°C. An appreciated capacity retention of 83.7% after 100 cycles with an initial discharge capacity of 177.1 mAh/g at 0.1C (discharge rate) has been achieved. Another cathode material with the formula of Li1.2 Mn0.51Ni0.145+xCo0.145-xO2 (x=0 (LR2), 0.0725 (LR1)), as a Li-rich cathode material, has been also successfully synthesized using glycerol. It was shown that LR1 discharge capacity was increased from 185 to 213 mAh/g after 20 cycles and ended up with 194.9 mAh/g after 60 cycles at 0.1C (discharge rate). This material shows an exceptional discharge capacity retention, lower toxic cobalt component, and lower production cost comparing with other Li-rich cathode materials. Detailed results of powder material synthesis, characterization, and battery testing will be presented to demonstrate that glycerol as a green solvent in the synthesis of battery materials.
