Materials Project releases trove of battery-related materials data to the public
The Materials Project, a searchable database of material properties, was launched in 2011 by the DOE’s Office of Science. It uses supercomputers to calculate the properties of materials based on first-principles quantum-mechanical frameworks. The Materials Project is designed to save researchers time by predicting the properties of materials, eliminating the need to synthesize them in… Read more »
New electrolyte for solid-state batteries combines polymer and glass
Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »
California Energy Commission awards $6 million for EV charging and V2G projects
The California Energy Commission has approved three alternative fuel infrastructure projects totaling more than $6 million. The investments, which were funded through the Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP), include: EV charging: Ten grants totaling more than $3.5 million for 181 EV charging stations to be installed along California highway corridors, and… Read more »
Sporty prototype demonstrates flow cell battery technology
Among the many electrified vehicles on display at this week’s Geneva Auto Salon was one that demonstrates a new and possibly revolutionary energy storage system. Leichtenstein-based nanoFLOWCELL’s QUANT e-Sportlimousine, a sleek sports model with gull-wing doors, uses flow cell battery technology. Scientists at GE Global Research and Lawrence Berkeley National Laboratory announced that they were… Read more »
Researchers find new non-flammable electrolyte for Li-ion batteries
A team of researchers has identified a new class of non-flammable electrolytes for lithium-ion batteries, based on perfluoropolyethers (PFPEs). In a paper published in the Proceedings of the National Academy of Sciences, the team reports that these electrolytes exhibit thermal stability beyond 200° C and a transference number of at least 0.91 (more than double… Read more »
Researchers demonstrate major advance in lithium-sulfur battery chemistry
Researchers at the Lawrence Berkeley National Laboratory have demonstrated a lithium-sulfur (Li/S) battery that has more than twice the specific energy of current lithium-ion batteries, and that lasts for more than 1,500 charge/discharge cycles with minimal capacity loss. This is the longest cycle life yet reported for any lithium-sulfur battery. The results were reported in the… Read more »
PARC’s new process deposits entire battery cell in one pass for big cost savings
PARC, a Xerox company, has launched a project with the DOE’s Advanced Research Projects Agency-Energy (ARPA-E) to demonstrate a new Li-ion battery manufacturing process that could dramatically reduce battery costs and improve performance. The conventional manufacturing process requires that the two halves of a battery be made in two separate steps, and then combined in… Read more »
Three of a kind: PolyPlus reaches for 1,500 Wh/kg
After decades of patent-protected breakthroughs, PolyPlus stands poised to make its first commercial move from its trio of power-dense battery technologies: lithium-sulfur, lithium-water, and lithium-air. It’s a balmy, 95-degree August day in the nation’s capital, but Steven J. Visco, PhD, the CEO, CTO, and co-founder of PolyPlus, sits in the climate-controlled comfort of the White House… Read more »
Strength in numbers: CalCharge battery consortium
A new public-private consortium, seeks to leverage the academic foundation and fertile entrepreneurial ground of the Bay Area to streamline new battery technology development.
