- Abstract
The increasing demands for higher energy density and higher power capacity of Li-ion secondary batteries have led to a search for electrode materials whose capacities and performance are better than those available today. One promising candidate is lithium manganese phosphate, and it is necessary to understand its transport properties. These properties are crucial for designing high-power Li-ion batteries. The effect on the electronic conductivity is analyzed with a conductor material, carbon nanotubes multi-walled, and glucose was used as a carbon source. Here, the transport properties of LiMnPO4, LiMnPO4/C, and LiMnPO4/MWCNT are investigated using impedance spectroscopy. The electronic conductivity is found to increase with increasing the temperature from 2.92 × 10−5 S cm−1 to 6.11 × 10−5 S cm−1. The magnetization properties are investigated, and antiferromagnetic behavior below 34 K is reported for the three compositions. The structural characterizations were studied to confirm the phase formation of material with XRD, TEM, and SEM.
