This research aims to develop a high-performance cathode by utilizing MWCNT and V2O5 materials for Li-ion batteries.
Developed a core/shell structure using multiwall carbon nanotube (MWCNT) coated with ALD V2O5.
Evaluated performance in terms of areal capacity and power density under varying current conditions.
Characterized electrochemical properties across a voltage range of 4.0-2.1 V.
Achieved a stable high areal capacity of 816 μAh/cm² at 1C (1.1 mA/cm²), 450 times higher than planar V2O5.
At a higher current (50×), the sponge demonstrated an areal capacity of 155 μAh/cm² and a power density of 21.7 mW/cm².
Showed exceptional robustness and energy-power characteristics for thin film cathode structures.
