Common battery electrolytes comprise organic carbonate solvents and fluorinated salts based on hexafluorophosphate (PF6–) anions. However, these suffer from high flammability, limited operating temperature window, cost. To address those issues, we here propose a fluorine-free electrolyte sodium bis(oxalate)borate (NaBOB). Although lithium (LiBOB) has previously been investigated for lithium-ion...

BACKGROUND In the United Kingdom, non-medical prescribing (NMP) has been identified as one way to improve healthcare quality and efficiency. Healthcare organisations are charged with overseeing the clinical governance of NMP and guidance recommends the identification of a lead director to be responsible for its implementation. While over twelve million items are prescribed each year by the 50,0...

Battery safety has been a very important research area over the past decade. Commercially available lithium ion batteries employ low flash point (< 80 °C), flammable, and volatile organic electrolytes. These organic based electrolyte systems are viable at ambient temperatures, but require a cooling system to ensure that temperatures do not exceed 80 °C. These cooling systems tend to increase ba...

This study was aimed at clarifying the effect of exposure to N-methyl-2-pyrrolidone (NMP) on workers' health. Fifteen male NMP-exposed workers and 15 referent male workers were recruited for this study. Exposure concentrations were assessed by determining NMP in the breathing zones and urinary NMP. Clinical examinations, motor and sensory nerve conduction velocities in the dominant arm, and neu...

The authors noticed that the values of exchange current density in Figures 1 c, 3 b, S6 and S16 were calculated incorrectly due to reverse x y axes during linear fitting. corrected by equation log i = (η−a)/b, presented revised (see Supporting Information published online along with this Corrigendum). Revised versions for c b are shown below. Instead having a negative correlation FEC content, a...

Nonaqueous solvents in modern battery technologies undergo electroreduction at negative electrodes, leading to the formation of a solid-electrolyte interphase (SEI). The mechanisms and reactions leading to a stable SEI on silicon electrodes in lithium-ion batteries are still poorly understood. This lack of understanding inhibits the rational design of electrolyte additives, active material coat...

High stable C/S composites are fabricated by a novel high-temperature sulfur infusion into micro-mesoporous carbon method following with solvent cleaning treatment. The C/S composite cathodes show high Coulombic efficiency, long cycling stability and good rate capability in the electrolyte of 1.0 M LiPF6 + EC/DEC (1:1 v/v), for instance, the reversible capacity of the treated C/S-50 (50% S) cat...

OBJECTIVES N-methyl-2-pyrrolidone (NMP) belongs to solvents widely used in the petrochemical industry a well as in the production of pesticides, veterinary drugs and paint removers. NMP is easily absorbed from the respiratory tract, digestive system and through the skin. It is a compound of slight acute toxicity that also displays moderate irritating activity. The aim of this study was to asses...

Neat N-methyl-2-pyrrolidone (NMP) rapidly penetrated into the skin of male Sprague-Dawley rats after in vivo and in vitro topical application. At the two topical doses tested in vivo, no steady state was observed. The maximal absorption fluxes were 10 and 20 mg/cm(2)/h for 20 microl/cm(2) and 40 microl/cm(2), respectively. Similar results were observed after in vitro topical application of neat...
