  • Patent number: 10978700
    Abstract: A nanoparticle and a method for fabricating the nanoparticle utilize a decomposable material yoke located within permeable organic polymer material shell and separated from the permeable organic polymer material shell by a void space. When the decomposable material yoke comprises a sulfur material and the permeable organic polymer material shell comprises a material permeable to both a sulfur material vapor and a lithium ion within a battery electrolyte the nanoparticle may be used within an electrode for a Li/S battery absent the negative effects of battery electrode materials expansion.

  • Publication number: 20200395593
    Abstract: Methods and systems are provided for fabricating a large format lithium ion electrochemical cell that includes an anode and a cathode. In one example, the anode is prepared via loading the anode to a predetermined anode loading amount, followed by electrochemical pre-lithiation of the anode via electrically coupling an auxiliary electrode to the anode where lithium is transferred to the anode through an electrolyte solution from the auxiliary electrode. In this way, pre-lithiation of the anode may be improved, which may in turn increase a capacity of the large format lithium ion electrochemical cell.

  • Publication number: 20200236995
    Abstract: The present invention relates to an electronic atomizing device including an atomizing assembly and a puff sensor electrically connected with the atomizing assembly. An air passage fluidly connected to the atomizing assembly and a starting passage fluidly connected between the airflow passage and the puff sensor are defined in the electronic atomizing device. The starting passage defines a receiving groove for receiving a condensed aerosol. The condensed aerosol is received by the receiving groove when flowing into the starting passage, and is prevented from flowing into a main body to cause damage to elements such as the power supply, the puff sensor and a PCB therein, thereby extending the service life of the main body.

  • Patent number: 10408806
    Abstract: Aspects of enhanced nanoscale gas chromatography are described. In one embodiment, a nano-scale gas chromatography (GC) module includes a light source, a light detector, and a sensor module having vertically-integrated photonic crystal slab (PCS) Fano resonance filter and GC channel layers. The PCS Fano resonance filter layer includes a hole lattice region, and the GC channel layer comprises a gas channel for separation of analytes in a gas mixture. The gas channel includes a coiled section and an extended length section, where the extended length section extends through a region in the GC channel layer that is stacked in proximity with the hole lattice region. The hole lattice region in the PCS Fano resonance filter layer provides local field enhancement of light generated by the light source for increased light-matter interaction with the analytes in the gas channel.
