Abstract
A nanohybrid containing 2 mol% La<sup>3+</sup>doped MnO<sub>2</sub>and carbon nanotubes produced hydrothermally exhibits a specific capacitance of ∼1530 F g<sup>−1</sup>at 1 A g<sup>−1</sup>and a 92% capacity retention after 5000 cycles showing its potential as electrode for supercapacitors.
