The lithium-sulfur battery has long been seen as a potential next generation battery chemistry for electric vehicles owing to the high theoretical specific energy and low cost of sulfur. However, even state-of-the-art lithium-sulfur batteries suffer from short lifetimes due to the migration of highly soluble polysulfide intermediates and exhibit less than desired energy density due to the requi...
The discharge of water from oil fields is become one the most significant environmental concerns associated with sector. This study features a low-density polysulfide polymer prepared by Sulfur and used sunflower oils react directly. Because both sulfur cooking are hydrophobic, can easily extract hydrocarbons like crude diesel fuel saltwater. petroleum industry by-product, leftover may be utili...
A new flow battery is presented using the abundant and inexpensive active material pairs permanganate/manganate disulfide/tetrasulfide. wetted set identified for compatibility with strongly oxidizing manganese couple at ambient elevated temperatures. Both solutions allow high solubility, cells tested theoretical energy densities up to 43 Wh l ?1 ?1.2 V cell. Full built nickel foam electrodes so...
Compared with monometallic selenides, heterogeneous bimetallic selenides have rich phase boundaries and superior electrical conductivity. ZnSe/CoSe2 composites were prepared by introducing Zn metal using ZIF-8/67 as the precursor through synergistic effect between Co after selenification. The electrocatalytic conversion of polysulfide is accelerated ZnSe chemical adsorption catalytic effect. co...
