Abstract: Methods, systems, and devices are disclosed for implementing a biofuel cell device for extracting energy from a biofuel. In one aspect, a biofuel cell device includes a substrate, an anode including a catalyst to facilitate the conversion of a fuel in a biological fluid in an oxidative process that releases electrons captured at the anode, thereby extracting energy from the fuel substance, a cathode configured on the substrate adjacent to the anode and separated from the anode by a spacing region, and a load electrically coupled to the anode and cathode via electrical interconnects to obtain the extracted energy as electrical energy.

Abstract: 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.
