摘要： Battery electrode compositions are provided for use in aqueous electrolytes and may comprise, for example, a current collector, active particles, and a conformal, metal-ion permeable coating. The active particles may be electrically connected to the current collector, and provided to store and release metal ions of an active material during battery operation. The conformal, metal-ion permeable coating may at least partially encase the surface of the connected active particles, whereby the conformal, metal-ion permeable coating impedes (i) direct electrical contact of an aqueous electrolyte with the active particles and (ii) aqueous electrolyte decomposition during battery operation. Such electrode compositions and corresponding aqueous batteries may facilitate the incorporation of advanced material synthesis and electrode fabrication technologies, and enable fabrication of high voltage and high capacity aqueous batteries at a cost lower than that of conventional metal-ion battery technology.

摘要： An energy distribution system. The energy distribution system has a housing with a rear terminal and a front terminal. An inlet unit receives air therethrough. The inlet unit then passes the air through a one-way valve into a reservoir where the air molecules undergo ionization. Once ionized, the gaseous air is converted into a plasma state. After being converted into the plasma state, electric energy is generated by a pair of magnets and stored in a capacitor.
