“…35−37 The electrostatic field-driven DIET can be explained by the Lorentz force that moves electrons, polar molecules, and charged ions. 28 However, in redox reactions, the electron transfer under electrostatic fields can also be described based on thermodynamics. 46 The equilibrium constant (K) for a redox reaction depends on the free energy change (ΔG = −RT × lnK, where R is the ideal gas constant, and T is the absolute temperature).…”

Direct interspecies electron transfer (DIET) is a breakthrough that can surpass the limitations of anaerobic digestion. Conductive materials and polarized bioelectrodes are known to induce DIET for methane production but are still challenging to apply at a field scale. Herein, compared to polarized bioelectrodes, electrostatic fields that promote DIET were investigated in an anaerobic reactor with conductive materials. As a conductive material, activated carbon enriched its surface with electroactive microorganisms to induce DIET (cDIET). cDIET improved the methane yield to 254.6 mL/g CODr, compared to the control. However, polarized bioelectrodes induced electrode-mediated DIET and biological DIET (bDIET), in addition to cDIET, improving the methane yield to 310.7 mL/g CODr. Electrostatic fields selectively promoted bDIET and cDIET for further methane production compared to the polarized bioelectrodes. As the contribution of DIET increased, the methane yield increased, and the substrate residue decreased, resulting in a significant improvement in methane production.

Lithium-ion batteries (LIBs) are currently the fastest growing segment of the global battery market, and the preferred electrochemical energy storage system for portable applications. Magnetism is one of the forces that can be applied improve performance, since the application of magnetic fields influences electrochemical reactions through variation of electrolyte properties, mass transportation, electrode kinetics, and deposits morphology. This review provides a description of the magnetic forces present in electrochemical reactions and focuses on how those forces may be taken advantage of to influence the LIBs components (electrolyte, electrodes, and active materials), improving battery performance. The different ways that magnetic forces can interact with LIBs components are discussed, as well as their influence on the electrochemical behavior. The suitable control of these forces and interactions can lead to higher performance LIBs structures and to the development of innovative concepts.

“…Considering the great power of coexistence or in interaction between the simple functions, the synergetic or cooperative effects between magnetic tailored fabrication and the optimization of the electrochemical behaviors as well as the magnetic active composite and the P/C constituent are well combined. Not only does the magnetic regulation help the homogeneous distribution of high quality of red phosphorus but magnetic effect has great enhancements of the electrochemical performance for such active materials. − The magnetic fabrication for both of the synthesis and improvement is deeply explored and systematically optimized in our study.…”

Red phosphorus (P) has recently attracted lots of interest due to its extraordinary theoretical capacity of 2596 mAh g in sodium-ion batteries (SIBs). However, it is challenging to solve the stability in the preparation process, while enhancing its low conductivity and solving the structural degradation caused by the enormous volume expansion (>490%) during cycling have become the targeted pursuits. Here, we creatively introduced the magnetic stimuli source to solve both of the preparation and the volume swelling force issues. In the precedence of magnetic field, the increased pressure in the sample room drives the homogeneous red P particles to finely deposit on the surface of FeO/C. The chain-like FeO/C/red P was successfully prepared assisted by the magnetic field. Simultaneously, considering that the speeded up movements for both electrons and sodium ions depended on Lorentz force, the electrochemical performance of such anode material is optimized by tuning the arrays in collector. It is noted that the nanostructure is elastically rearranged for the resistance of volume swelling force. Compared with the single FeO/C/red P particles, for the magnetic fabricated FeO/C/P chain structure, the electrostatic potential for reconstructing the chain-like FeO/C/P is the largest. Such configured chain-like anode material exhibits an extraordinary cyclic performance and superior rate capability (692 mAh g at 2000 mA g). The magnetic stimuli source bridges both the preparation optimization and the electrochemical performance enhancements for the red P based anode materials.
