Abstract Ammonium nitrate is a hygroscopic and caking product for growing agricultural products. In order to improve the properties of ammonium nitrate, composition calcined crushed cathode material from used lithium ion battery was studied. Since mainly consists lithium, cobalt, manganese nickel, it has been adopted as polymicroelement-containing additive nitrate. Studies have shown that intro...

For a large amount of spent lithium battery electrode materials (SLBEMs), direct recycling by traditional hydrometallurgy or pyrometallurgy technologies suffers from high cost and low efficiency even serious secondary pollution. Therefore, aiming to maximize the benefits both environmental protection e-waste resource recovery, applications SLBEM containing redox-active transition metals (e.g., ...

Battery swapping is a promising technology when compared with the traditional electric vehicle charging stations. The time spent at battery station might be similar to filling station. article presents information on attempts implement this solution, methods of swapping, infrastructure and operation stations, as well benefits key challenges technology.

Twelve medical house officers were tested on a battery of memory, concentration, and work related tasks after three conditions: a night spent off duty; a night spent on call; and a night spent admitting emergency cases. Short term recall, but not digit span, concentration, or work related abilities, was impaired after a night of emergency admissions. A night spent on call had no effect on cogni...
