![]() The results suggest pathways for optimizing the electrode morphology in supercapacitorsusing ultra-high volume fraction VA-CNTs to further enhance performance. By employing both the electric and electromechanical spectroscopes, as well as nanostructured materials characterization, the ion transport and storage behaviors in porous electrodes are studied. ![]() We investigate the charge-discharge characteristics of VA-CNTs with >20 vol% of CNT and ionic liquids as electrolytes. Recent advances in fabricating controlled-morphology vertically aligned carbon nanotubes (VA-CNTs) with ultrahigh volume fractioncreate unique opportunities for developing unconventional supercapacitors with ultra-high energy density, power density, and long charge/discharge cycle life.Continuous paths through inter-VA-CNT channels allow fast ion transport, and high electrical conduction of the aligned CNTs in the composite electrodes lead to fast discharge speed. Ghaffari, Mehdi Zhao, Ran Liu, Yang Zhou, Yue Cheng, Jiping Guzman de Villoria, Roberto Wardle, B. Ultra-high density aligned Carbon-nanotube with controled nano-morphology for supercapacitors This allows the proposed generator having the potential to offer even higher torque density than its integrated MG. Investigation on the magnetic field harmonics demonstrates that the permanent-magnetic torque offered by the MG can work together with the electromagnetic torque offered by the armature windings to balance the driving torque captured by the wind turbine. The performance is analyzed using finite element method. This makes it with good controllability and high power factor as the surface-mounted permanent magnet machines. Nevertheless, due to lack of back iron on the stator, the proposed generator does not exhibit prominent salient feature, which usually exists in traditional interior PM (IPM) machines. Interior permanent magnet (PM) design on the inner rotor is adopted to boost the torque transmission capability of the integrated MG. Second, armature windings are engaged to achieve electromechanical energy conversion. First, magnetic gear (MG) is integrated to achieve non-contact torque transmission and speed variation. The purpose of this paper is to propose a new direct-drive wind power generator (DWPG), which can offer ultra-high torque density. In order to get rid of the nuisances caused by mechanical gearboxes, generators with low rated speed, which can be directly connected to wind turbines, are attracting increasing attention.
