    Abstract: A chip assembly for measuring an electrochemical reaction on a solid-liquid phase interface in situ, comprising a first electrode, a second electrode, a first insulating film, a second insulating film, a third insulating film, a fourth insulating film and an upper chip and a lower chip which are oppositely arranged and of which two sides are correspondingly combined in a sealing manner; a through hole is provided on the upper chip; the first insulating film under the through hole is provided with the first electrode; a groove opposite to the through hole is provided on the lower chip; and the fourth insulating film arranged at one side of the groove is provided with the second electrode. The chip assembly dispenses with a specially-made sample rod, thereby substantially reducing test cost; and meanwhile, a lattice structure of a first electrode is also beneficial for observing topography change of a to-be-tested sample.

  • Patent number: 9853284
    Abstract: The loss of sulfur cathode material as a result of polysulfide dissolution causes significant capacity fading in rechargeable lithium/sulfur cells. Embodiments of the invention use a chemical approach to immobilize sulfur and lithium polysulfides via the reactive functional groups on graphene oxide. This approach obtains a uniform and thin (˜tens of nanometers) sulfur coating on graphene oxide sheets by a chemical reaction-deposition strategy and a subsequent low temperature thermal treatment process. Strong interaction between graphene oxide and sulfur or polysulfides demonstrate lithium/sulfur cells with a high reversible capacity of 950-1400 mAh g?1, and stable cycling for more than 50 deep cycles at 0.1 C.

  • Publication number: 20170125800
    Abstract: The invention provides a nitrogen-doped graphene coated nano sulfur positive electrode composite material, a preparation method, and an application thereof. The composite material includes: an effective three-dimensional conductive network formed by overlapping of nitrogen-doped graphenes, and nano sulfur particles coated by nitrogen doped graphene layers evenly. The preparation method includes: dispersing nitrogen-doped graphenes in a liquid-phase reaction system including at least sulfur source and acid, and depositing nano sulfur particles by an in-situ chemical reaction of the sulfur source and the acid, thereby preparing the positive electrode composite material. The positive electrode composite material of the invention has a high conductivity, a high sulfur utilization rate, and a high rate, thereby restraining the dissolution and shuttle effect in the lithium sulfur batteries, and enhancing the cyclic performance of the batteries.

  • Publication number: 20160141620
    Abstract: A long-life, high-rate lithium sulfur (Li/S) cell with high specific energy uniquely combines cetyltrimethyl ammonium bromide (CTAB)-modified sulfur-graphene oxide (S-GO) nanocomposites with an elastomeric styrene butadiene rubber (SBR)/carboxy methyl cellulose (CMC) binder and an ionic liquid-based novel electrolyte with the LiNO3 additive. A Li/S cell employing a CTAB-modified S-GO nanocomposite cathode can be discharged at rates as high as 6C (1C=1.675 A/g of sulfur) and charged at rates as high as 3C while still maintaining high specific capacity (˜800 mAh/g of sulfur at 6C), with a long cycle life exceeding 1500 cycles, the longest cycle life with extremely low decay rate (0.039% per cycle) demonstrated so far for a Li/S cell.

  • Patent number: 9267944
    Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.
