Electrochemical Devices Comprising Compressed Gas Solvent Electrolytes
Disclosed are novel electrolytes, and techniques for making and devices using such electrolytes, which are based on compressed gas solvents. Unlike conventional electrolytes, disclosed electrolytes are based on compressed gas solvents mixed with various salts, referred to as compressed gas electrolytes. Various embodiments of a compressed gas solvent includes a material that is in a gas phase and has a vapor pressure above an atmospheric pressure at a room temperature. The disclosed compressed gas electrolytes can have wide electrochemical potential windows, high conductivity, low temperature capability and/or high pressure solvent properties. Examples of a class of compressed gases that can be used as solvent for electrolytes include hydrofluorocarbons, in particular fluoromethane, difluoromethane, tetrafluoroethane, pentafluoroethane. Also disclosed are battery and supercapacitor structures that use compressed gas solvent-based electrolytes, techniques for constructing such energy storage devices. Techniques for electroplating difficult-to-deposit materials using compressed gas electrolytes as an electroplating bath are also disclosed.

Methods and apparatuses for dynamically tunable wafer-edge electroplating
Disclosed herein are methods of electroplating which may include placing a substrate, an anode, and an electroplating solution in an electroplating cell such that the substrate and the anode are located on opposite sides of a fluidically-permeable plate, setting the configuration of one or more seals which, when in their sealing configuration, substantially seal pores of the fluidically-permeable plate, and applying an electrical potential between the anode and the first substrate sufficient to cause electroplating on the first substrate such that the rate of electroplating in an edge region of the first substrate is affected by the configuration of the one or more seals. Also disclosed herein are apparatuses for electroplating which may include one or more seals for substantially sealing a subset of the pores in a fluidically-permeable plate whose sealing configuration affects a rate of electroplating in an edge region of the substrate.
