Magnetic field energy storage of ferromagnetic materials

What is ferromagnetism in physics?

Ferromagnetism describes the phenomenon whereby a material can be magnetised permanently, with variable strength, and reversibly - by an applied magnetic field. Atoms are structured so that electrons prefer to sit in pairs in their orbits so that each pair contains electrons with opposite spin, and the orbits are filled from low to high energy.

What are the underlying mechanisms of magnetic fields in electrochemical energy storage?

The underlying mechanisms of magnetic fields in Electrochemical Energy Storage (EES) are discussed. Magnetic field induced structural and morphological changes during fabrication of electrode materials are discussed. Various parameters governing the electrochemical performance of EES devices under external magnetic field are studied.

How does a magnetic field affect energy storage performance?

The magnetic field influenced the synthesis of magnetic electrode materials, fabrication of electrodes, and electrochemical performance of these devices are compiled in different sections. The underlying mechanism behind the energy storage performance of these devices under a magnetic field is comprehensively discussed with suitable examples.

What are ferromagnetic materials used for?

From now on we will focus on ferromagnetic materials as they are used most frequently in applications ranging from magnetic data storage to power generation. Last lecture we have shown how the fermionic nature of electrons leads to the spontaneous ordering of the magnetic dipoles inside the ferromagnetic material.

Can magnetic fields be used in energy storage devices?

In summary, the application of magnetic fields in energy storage devices has just found a path. Based on its evidence of a positive effect on performance, its optimization and removal of shortcomings need deep and comprehensive exploration.

Can magnetic field as Non-Contact Energy improve electrochemical performance of energy storage devices?

To further improve the efficiency, energy, and power capacity of these devices, scalable and effective approaches providing end-to-end solutions are most desirable. As evidenced by several reports, magnetic field as non-contact energy has emerged as a powerful tool to boost the electrochemical performance of energy storage devices.
