New microscopy system delivers real-time view of battery electrochemistry
You may not think about what’s going on inside the battery when you charge your EV, but the fate of the world may hang on the diminutive dramas taking place in there between the electrodes. Researchers at the Oak Ridge National Laboratory have used a new microscopy technique to get perhaps the best glimpse yet… Read more »
CalBattery’s new SiGr anode material hopes to break the battery bottleneck
California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »
A123 and SolidEnergy work together on safer, 800 Wh/kg battery chemistry
A123 Venture Technologies, the R&D subsidiary of the mercurial manufacturer of EV batteries, has announced a strategic partnership with MIT startup SolidEnergy. SolidEnergy’s solid electrolyte technology enables the use of lithium metal anodes for high energy density batteries. The new partnership combines SolidEnergy’s Solid Polymer Ionic Liquid (SPIL) electrolyte with the cell design and prototyping… Read more »
University of Colorado researchers to commercialize new solid-state battery
The University of Colorado Boulder (CU) has signed an agreement with Solid Power LLC, a spin-off company, to develop and commercialize a solid-state battery technology that has the potential to greatly improve EV range. Solid Power, founded by Se-Hee Lee and Conrad Stoldt, both associate professors of mechanical engineering, was recently awarded a $3.4 million… Read more »
Oak Ridge researchers give solid Li-ion electrolytes a new spin
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
ARPA-E’s new RANGE program offers $20m for battery research
If you think you can develop an EV battery that delivers three times the range for a third less cost than current designs, you can claim a slice of $20 million in research funding from the DOE’s Advanced Research Projects Agency – Energy (ARPA-E). The agency has issued a funding opportunity announcement (FOA) for the… Read more »
Two materials firms join IBM’s Li-air Battery 500 Project
IBM announced Friday that Asahi Kasei and Central Glass will join its Battery 500 Project team to collaborate on research into lithium-air batteries. The two companies have some very pertinent expertise, due to their existing work with lithium-ion batteries – Chemical manufacturer Asahi Kasei makes separator membrane, and Central Glass supplies electrolytes. The… Read more »
Researchers demonstrate a four-electron reaction that improves energy density in Li-air batteries
Lithium-air batteries could theoretically deliver an energy density comparable to that of gasoline. However, in most systems, the reaction pathways either involve one- or two-electron transfer, leading to lithium peroxide (Li2O2) or lithium superoxide (LiO2), respectively. Researchers at the Illinois Institute of Technology and Argonne National Laboratory are investigating a way to create a lithium-air… Read more »
A closer look at graphite—its forms, functions and future in EV batteries
Q&A with Graphex CEO John DeMaio Reading the EV press, you might assume that lithium, cobalt and nickel are the stars of the battery show—they get a lot of coverage, as pundits debate the relative merits of NMC and LFP cathode chemistries and agonize over looming shortages. Meanwhile, over in the anode, there’s an unsung… Read more »
