  • Patent number: 11992093
    Abstract: The present invention provides a device for improving energy economy and wearing comfort of a power generating, gait assisting footwear article while maintaining normal gait pattern during human locomotion. The device includes a motion conversion mechanism to convert linear reciprocating moment exerted on the device during heel strike/up into a series of rotations; a rotation acceleration module to increase the speed of rotations before being transformed into electric current by a generator. The device also includes a power management module and energy storage element(s) for energy storage and power supply to the footwear article or external electronics.

  • Publication number: 20220271280
    Abstract: Disclosed are a lithium negative electrode with a protective layer (1), a preparation method and an application thereof. The protective layer (1) of the lithium negative electrode is located on a surface of the electrode, and the protective layer (1) is a lithiated perfluorosulfonic acid membrane doped with nano molybdenum disulfide (3). The preparation method for the lithium negative electrode with the protective layer (1) comprises the following steps of: I. lithiation of a perfluorosulfonic acid; II. loading of the molybdenum disulfide (3); and III. coating and curing of the protective layer (1). The protective layer (1) of the lithium metal negative electrode of a lithium battery is capable of effectively inhibiting lithium dendrites, and weakening a shuttle effect, thereby improving a charge and discharge capacity, a rate capability and a cycle life of a lithium-sulfur battery.
