An energy storage solution for the future

Abandoned mine sites in the United States can create environmental disturbances that last decades or longer.This talk proposes an idea that not only permanently rehabilitates such sites, but re-purposes them to create a renewable energy power plant large enough to allow entire cities to rely 100 percent on intermittent renewable energy sources like wind or solar power.

Green power unleashed: Plant extracts forge oxygen bridges for

The reversibility and cycling stability of aqueous zinc-ion batteries (AZIBs) are largely limited by serious parasitic reactions and uncontrolled dendrites growth. Herein, caulis polygoni multiflori extract (CPM) has been proposed as electrolyte additive to build a convenient bridge to clear the way for Zn2+ to migrate to the zinc plate. CPM can set up "oxygen bridges" between Zn plate

Flower‐like Vanadium Suflide/Reduced Graphene Oxide

A flower‐like vanadium sulfide/reduced graphene oxide (VS4/rGO) composite was prepared by a typical hydrothermal method and it was investigated as cathode for aluminum‐ion batteries with non‐inflammable and non‐explosive ionic‐liquid electrolytes. The charge/discharge performance measurements were performed in a voltage range of 0.1–2.0 V versus Al/AlCl4−, which gave

Iron carbide allured lithium metal storage in carbon nanotube

The controversies on the metallic lithium storage in the carbon nano-pores have never stopped for more than three decades since Sato speculated the formation of Li 2 molecules in the porous carbon to explain its high lithium storage capacity. Herein, we successfully realized lithium metal storage in the cavities of the carbon nanotubes (CNTs) and directly observed the

Polymer electrolytes based on interactions between [solvent-Li+

Poly(vinylidene fluoride) (PVDF) is the most popular electrode binder in the current lithium ion batteries (LIBs). Depending on solvent content, polymer electrolytes are classified into solid polymer electrolyte (SPE; solvent-free) and gel polymer electrolytes (GPE; solvent-rich). PVDF-based electrolytes with high contents of solvent undisputedly belong to GPE.
