One-step synthesis of MnOx/PPy nanocomposite as a high-performance cathode for a rechargeable zinc-ion battery and insight into its energy storage mechanism.

Nanoscale, 2020
Rechargeable aqueous zinc-ion batteries (ZIBs) have attracted significant attention in the energy storage field. Manganese-based materials are the most promising cathode materials for ZIBs but they suffer from low electronic conductivity.

MECHANICAL OSCILLATOR WITHOUT POTENTIAL ENERGY STORAGE

Transport engineering, 2022
In a monoreactive harmonic oscillator, inert elements can make free sinusoidal oscillations, which are accompanied by the transformation of one inert element kinetic energy into the kinetic energy of another inert element. In this condition the energy of the first inert element is zero. At the same time, the energy of the second element has the maximum

Energy Storage and Exchange Mechanisms in Turbulent Media

Journal of Non-Equilibrium Thermodynamics, 1991
In this study modes of excitation are investigated that could be part of the internal energy, and the energy transfer mechanisms are described that likely contribute to the establishment of equilibrium in fully developed turbulence. We treat turbulence as a thermodynamic system in which equilibrium is mainly achieved through binary encounters between ...

Superstrong Ultralong Carbon Nanotubes for Mechanical Energy Storage

Advanced Materials, 2011
Energy storage in a proper form is essential for a good grid strategy. The systems developed so far mostly use batteries or capacitors in which energy is stored electrochemically or electrostatically. Mechanical energy storage is also one of the most important ways for energy conversion.
