Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.
Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.
Researchers led by a team from Griffith University in Australia have developed a multifunctional polymer binder that not only maintains the outstanding binding capabilities of sodium alginate but also enhances the mechanical integrity and lithium-ion diffusion coefficient in a LiFePO 4 (LFP) electrode during the operation of the batteries.
To yield more oil, water may be injected into the reservoir to maintain pressure in order to keep the flow moving. Engineers may also make the water more alkaline by adding sodium hydroxide or sodium carbonate to help the oil flow better. —Yuichiro Nagatsu.
of weight a rider carries, an additional 700 watt-hours of energy is available (compared to ~350 watt-hours for an ultra-high performance lithium-polymer battery at a weight of 7 lbs.). A key innovation is the use of sodium silicide to liberate hydrogen from water as needed by the hybrid fuel cell. For every 1.5 Earlier post.)
Proton exchange membrane (PEM) electrolyzers use a solid polymer electrolyte, and alkaline electrolyzers use an electrolyte solution, such as potassium hydroxide or sodium hydroxide mixed with water. Cummins currently manufactures both PEM and alkaline electrolyzers.
The FHR is a new reactor concept that combines high-temperature graphite-matrix-coated particle fuel developed for high-temperature gas-cooled reactors; liquid salt coolant developed for molten salt reactors; and safety systems originating with sodium fast reactors.
Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion with new cathode chemistries are appropriate. Advanced Batteries for Transportation. The focus is on high-energy density and high-power density batteries suitable for transportation applications.
Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion electrochemical energy storage are appropriate. Photocatalytic or photoelectrochemical processes for the splitting of water into H 2 gas, or for the reduction of CO 2 to liquid or gaseous fuels are appropriate.
A team at the University of Maryland has demonstrated that a material consisting of a thin tin (Sn) film deposited on a hierarchical conductive wood fiber substrate is an effective anode for a sodium-ion (Na-ion) battery, and addresses some of the limitations of other Na-ion anodes such as capacity fade due to pulverization. —Zhu et al.
Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion electrochemical energy storage are appropriate. Advanced Batteries for Transportation and Renewable Energy Storage. The focus is on high-energy density and high-power density batteries suitable for transportation and renewable energy storage applications.
At present, pretreatment techniques include physical, chemical, physicochemical and/or biological methods such as steam explosion; hot water extraction; sulfuric acid; sodium hydroxide; hydrogen peroxide; peracetic acid; ammonia fiber explosion (AFEX); and wet oxidation in addition to an emerging body of work on ozonolysis.

Demonstration of Sodium Ion Battery for Grid Level Applications. DOE funding $75,161,246, total project value with cost share $150,322,492). 16,080,554. Seeo, Inc (CA).
Water (1 project). Eagle Picher, in partnership with the Pacific Northwest National Laboratory, will develop a new generation of high energy, low cost planar liquid sodium beta batteries for grid scale electrical power storage applications. Affordable Energy from Water and Sunlight. Waste Heat Capture (2 projects).
A friction-reducing polymer coating on the piston skirts, as well as fully floating wrist pins that help reduce friction. mm sodium-filled exhaust valves enable the engine to process tremendous airflow. Because the Cadillac Twin-Turbo is based on the same architecture as the existing naturally aspirated 3.6L Large, 38.3-mm
Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate. A team including researchers from Japan’s Tohoku University recently developed a durable, efficient energy harvester that combines piezoelectric composites with carbon-fiber-reinforced polymer (CFRP).
Unlike conventional systems, which force coolant flow from the front of the block to the back, the new patented targeted cooling system sends coolant simultaneously to each water jacket in the heads and block. Features shared by the 3.0L Twin Turbo and 3.6L New cylinder head design. Additional features unique to the 3.0L
Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge. This area currently has three areas of focus: Intermediate temperature solid oxide fuel cells; Polymer electrolyte fuel cells; and. Rechargeable metal-air batteries.
