  • Patent number: 10570900
    Abstract: Disclosed is an oil separation barrel, which includes a barrel body and an oil separation and filtration structure provided in the barrel body, the barrel body provided with an oil separation cavity and an output port. An output gas flow is filtered by the oil separation and filtration structure, then enters the oil separation cavity, and finally is output from the output port. At least part of a barrel wall of the barrel body forming the oil separation cavity includes two or more layers of circumferential walls. The output gas flow flows in the oil separation cavity in such a manner that it changes the advance direction multiple times, which can make the flow field uniform and reduce noise and vibration; and the output gas flow impacts the circumferential wall surfaces in the oil separation barrel multiple times, which can further improve the efficiency of oil separation.

  • Patent number: 10438753
    Abstract: This invention described the preparation of a series of compounds that can be used as co-solvents, solutes or additives in non-aqueous electrolytes and their test results in various electrochemical devices. The inclusion of these novel compounds in electrolyte systems can enable rechargeable chemistries at high voltages that are otherwise impossible with state-of-the-art electrolyte technologies. These compounds are so chosen because of their beneficial effect on the interphasial chemistries formed at high potentials, such as 5.0 V class cathodes for new Li ion chemistries. The potential application of these compounds goes beyond Li ion battery technology and covers any electrochemical device that employs non-aqueous electrolytes for the benefit of high energy density resultant from high operating voltages.
