New multifunctional polymer binder achieves theoretical capacity of LiFePO4 Li-ion batteries without additives

Green Car Congress

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.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

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.

TUAT team develops more efficient method to recover heavy oil using novel chemical flooding

Green Car Congress

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.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

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.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

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.

NSF to award $13M to projects focused on electrochemical and organic photovoltaic systems

Green Car Congress

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.
