Anode-Free Rechargeable Battery
SYSTEM AND PROCESS FOR PRODUCTION OF MAGNESIUM METAL AND MAGNESIUM HYDRIDE FROM MAGNESIUM-CONTAINING SALTS AND BRINES (iEdison No. 0685901-13-0017)
A system and process are disclosed for production of consolidated magnesium metal products and alloys with selected densities from magnesium-containing salts and feedstocks. The system and process employ a dialkyl magnesium compound that decomposes to produce the Mg metal product. Energy requirements and production costs are lower than for conventional processing.
Salt-In-PreSalt electrolyte solutions for high-potential non-aqueous sodium metal batteries
METALLIZATION PATTERN ON SOLID ELECTROLYTE OR POROUS SUPPORT OF SODIUM BATTERY PROCESS
A new battery configuration and process are detailed. The battery cell includes a solid electrolyte configured with an engineered metallization layer that distributes sodium across the surface of the electrolyte extending the active area of the cathode in contact with the anode during operation. The metallization layer enhances performance, efficiency, and capacity of sodium batteries at intermediate temperatures at or below about 200° C.
HIGH PERFORMANCE REDOX FLOW BATTERY STACK
A redox flow battery stack cell frame comprising a support frame and a monolithic bipolar plate integrated within the support frame is disclosed. The bipolar plate comprises a plurality of interdigitated flow channels on at least one surface. The support frame comprises an inlet manifold formed into a facing surface of the first side of the frame, the inlet manifold comprising fluid inlet distribution channels in a serpentine arrangement, each fluid inlet distribution channel aligned with a single inlet flow channel of the bipolar plate; and an outlet manifold formed into the facing surface of the opposing side of the frame, the outlet manifold comprising fluid outlet distribution channels in a serpentine arrangement, each fluid outlet distribution channel aligned with a single outlet flow channel of the bipolar plate. Redox flow battery stack cells and stacks comprising the stack cell frame are also disclosed.
Saltwater Exposure Affects Leaf Structure in a Coastal Forest
The results of this study are consistent with the idea that the stress of chronic salinity exposure changes tree leaf shape and function, weakening their physiology and setting in motion processes that lead to death.
