Quasi-Commercial Pouch Sodium-Ion Battery Capacitors Achieve Extended High-Power Cyclability Through Na₃V₂(PO₄)₃/Activated Carbon Hybrid Cathode Design with Presodiation-Free Anodes

Batteries
Sodium–ion battery capacitors (SIBatCs) synergistically combine battery–type and capacitor–type components in an inter–parallel configuration, simultaneously delivering high energy and power densities. We pioneer the development of quasi–commercial pouch

Accurate supercapacitor modeling for energy-harvesting wireless sensor nodes

, 2011
Supercapacitors are often used in energy-harvesting wireless sensor nodes (EH-WSNs) to store harvested energy. Until now, research into the use of supercapacitors in EH-WSNs has considered them to be ideal or over-simplified, with non-ideal behavior ...

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a
