  • Patent number: 9653765
    Abstract: The present invention generally relates to batteries and, in particular, to electrodes for use in batteries such as non-aqueous metal-air batteries, for example, lithium-air batteries, as well as in other electrochemical devices. Such devices may exhibit improved performance characteristics (e.g. power, cycle life, capacity, etc.). One aspect of the present invention is generally directed to electrodes for use in such devices containing one or more pores or channels for transport of gas and/or electrolyte therein, e.g., forming an open porous network. In certain embodiments, the electrolyte may be a gel or a polymer. In some embodiments, there may be network of such channels or pores within the electrode such that no active site within the electrode is greater than about 50 micrometers distant from a gas channel.

  • Patent number: 9441120
    Abstract: Lithographic printing inks are described, which are characterized by the inclusion of both water, in a substantially emulsified form, and inorganic filler. Inks of the present invention show improved printing properties in offset lithography, including improved transfer, reduced piling and improved mileage. They also offer cost advantages over currently available inks and the ability to minimize or eliminate entirely mineral oil from their compositions. The inks of the present invention may be used in both web-based print processes including coldset and heatset, as well as in sheetfed printing. The inks may be dried to a durable ink film at ambient temperature, with thermal energy or with actinic or electron beam radiation, or with any combination thereof.
