General description

1-Butyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
Solvene® electro-active polymer is a family of ferroelectric polymers and ferrorelaxor polymers which combines excellent electro mechanical properties with easy processing.
Solvene®250 P(VDF-TrFE) copolymers are inherently piezo-, pyro- and ferroelectric, enabling applications such as printed memories, sensors, actuators, loudspeaker, acoustic transducers, energy harvesting devices.
Solvene® materials can be processed by applying various techniques, from classic extrusion to different printing techniques on various substrates which include flexible plastic films or paper.
