    Abstract: Techniques and implementations pertaining to an integrated gas diffusion layer with a sealing function are described. A method for making the integrated gas diffusion layer with the sealing function may involve placing a gas diffusion member inside a mold followed by injecting a sealing material into the mold. The method may also involve having the sealing material substantially covers a peripheral portion of the gas diffusion member and at least partially penetrates into a peripheral portion of the gas diffusion member. The method may further involve curing the sealing material to form a sealing member having a lip ring.

  • Patent number: 9676640
    Abstract: A method of making a micro-channel electrode structure includes providing a curable layer and imprinting the curable layer to form an electrode micro-channel and a fluid micro-channel in a common step. The electrode micro-channel intersects the fluid micro-channel to form a micro-channel intersection. The curable layer is cured to form an imprinted cured layer. Both the electrode and the fluid micro-channels are filled with a developable material that is exposed with an electrode pattern including the electrode micro-channel and extending from the electrode micro-channel into the micro-channel intersection without occluding the fluid micro-channel. The exposed developable material is developed to remove the developable material from the electrode pattern and the electrode micro-channel and the micro-channel intersection corresponding to the electrode pattern are at least partly filled with a conductive material. At least a portion of the remaining developable material is removed from the fluid micro-channel.

  • Patent number: 9673452
    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.
