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. In some embodiments, such systems may be created using electrodes containing gel or electrolyte polymers, and/or by forming electrodes having different wettabilities such that certain regions preferentially attract the electrolyte compared to other regions, thereby causing self-organization of the electrolyte within the electrode. Other aspects of the invention are generally directed to methods of making such batteries or electrochemical devices, methods of using such batteries or electrochemical devices, kits involving such batteries or electrochemical devices, or the like.

Abstract: High capacity and high voltage Li-ion batteries that have a carbonaceous cathode and a nonaqueous electrolyte solution comprising LiF salt and an anion receptor that binds the fluoride ion. The batteries can comprise dual intercalating electrode Li ion batteries. Methods of the present invention use a cathode and electrode pair, wherein each of the electrodes reversibly intercalate ions provided by a LiF salt to make a high voltage and high specific capacity dual intercalating electrode Li-ion battery. The present methods and systems provide high capacity batteries particularly useful in powering devices where minimizing battery mass is important.
