Sulfur is an exciting cathode material with high specific capacity of 1,673 mAh/g, more than five times the theoretical limits of its transition metal oxides counterpart. However, successful applications of sulfur cathode have been impeded by rapid capacity fading caused by multiple mechanisms, including large volume expansion during lithiation, dissolution of intermediate polysulfides, and low...
Background and Objectives According to Islamic doctrines, the use of gold for men has been banned. In general, any advised subject in Islam is useful for the body and what has definitely forbidden for a man is definitely harmful for him although its reasons have not been exactly specified. However, Muslims believe that there is certainly a sound reason behind this prohibition. This issue was st...
To overcome the low lithium ion diffusion and slow electron transfer, a hollow micro sphere LiFePO₄/C cathode material with a porous interior structure was synthesized via a solvothermal method by using ethylene glycol (EG) as the solvent medium and cetyltrimethylammonium bromide (CTAB) as the surfactant. In this strategy, the EG solvent inhibits the growth of the crystals and the CTAB surfacta...
