摘要:
Embodiment herein provide a supercapattery comprising a housing having a plurality of negative electrode (1) and positive electrode (2) sets, a first porous separator layer (3) placed in between negative electrode (1) and 10 positive in each negative electrode (1) and positive electrode (2) set of the plurality of negative electrode (1) and positive electrode (2) sets, and a second porous separator layer (3') placed in between each two negative electrode (1) and positive electrode (2) set of the plurality of negative electrode (1) and positive electrode (2) sets. The negative electrode (1) 15 comprises a current collector (4) coated with a porous layer of same active material of variable thickness on both sides (5, 6) of the current collector (4). The positive electrode (2) comprises a current collector (7) coated with a porous layer of different active materials on either sides (8, 9) of the current collector (7).
摘要:
An electrode includes an insulating surface layer and at least one aligned carbon nanotube fiber embedded in the insulating surface layer. Each of the at least one aligned carbon nanotube fiber has a first end and a second end opposite the first end, and the first end and the second end are separated by a body. Each of the at least one aligned carbon nanotube fiber is composed of a plurality of carbon nanotubes. The first end and the second end are free of the insulating surface layer. The second end is in contact with an electrical conductive material. A method of analyzing an analyte in a sample and a device for energy storage using the electrode are also described.
摘要:
Electrochemical energy storage devices utilize ionic conducting electrolyte solution to carry charge between positive and negative electrodes. The electrolyte solutions use a mixture of solvent and salt and additional components, or additives, for improved electrochemical stability of the device. In an exemplary embodiment, an electrochemical device includes an electrolyte and housing to provide a pressurized condition for the electrolyte, and electrodes in contact with the electrolyte.
