As the reactivity of the active material
of the negative electrode of conventional nickel-cadmium batteries is reduced at low temperatures, charging/discharging under 0 deg C was difficult with the previous products*3.
The amount of active material
can be significantly reduced if it is not used as a substrate to provide mechanical support.
Ion Technology's unparalleled ease of production and high energy density for a given volume is made possible by the fact that the active material
needs no separator between it and the two poles.
To create the material, scientists from the research facility and from the state-run Tohoku University in Sendai, Miyagi Prefecture, combined benzene, commonly used as a solvent, and silica, used as a drying agent in confectioneries, with an active material
Weight for weight saffron and Safrante contain the same amount of active material
, but the instant solubility means usage rates of 50% or less, and a cost reduction of 30-40%.
Making the active material
in the battery a thin film allows for very fast charging and discharging, but reduces the capacity to nearly zero because the active material
lacks volume to store energy.
Cocamide DEA is also a high active material
with no water or solvent in it.
Hutchinson of Paris, France has obtained a patent for a paint or varnish composition comprised of from 10-50 parts by weight of at least one polyurethane in aqueous emulsion form; from 10-30 parts by weight of at least two acrylic polymers or copolymers in aqueous emulsion form; from 10-70 parts by weight of mineral or organic fillers; from 5-20 parts by weight of processing aids; and from 0-10 parts by weight of crosslinking agent; from 40-150 parts by weight of water; wherein the parts are based on the weight of active material
in the composition; wherein the at least two acrylic polymers or copolymers are chosen in such a way that one has a glass transition temperature between 0[degrees]-5[degrees] C and the other has a glass transition temperature between 40[degrees]-30[degrees] C.
It is possible to produce microcapsules containing high loads of the core active material
and which have protection against oxidation.
Contract notice: Project broadband infrastructure in planning regions of the country brandenburg - fiberglass 2020 planning region 5 north - delivery of active material
for the development of broadband infrastructure in the state of brandenburg, planning region 5 north.
Firstly, there are fears that it may contain traces of chemical or radio active material
and secondly another point of contention is the fact that there is a North Korean government official onboard, which prompts questions on the credibility of the claim that the ship is a merchant vessel.
EKFA-3600 is 100% active material
and is also available in a 50% active version marketed as EFKA3650.
