Lithium-air batteries are widely expected to be the next big thing – more than 300 research papers have been published on the topic in the past 3 years. Li-air has the potential to deliver far more energy density than current lithium-ion technology. A new review in the ACS journal Chemical Reviews sums up the current… Read more »

New microscopy technique gives researchers a better look inside batteries
Electricity may seem invisible, but storing it in batteries has some very physical effects. As a battery is charged and discharged, electrons and ions rush around from place to place, sometimes causing electrodes to change their shapes over time. As researchers experiment with improved electrode materials, it’s critical to get a microscopic view of what… 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 »
Electric car sharing takes off in Paris, stalls in Berlin
Some see car sharing as a killer app for EVs – users make short journeys, return the cars to central locations, and pay per trip, so they don’t have to worry about high up-front costs. Others are more skeptical, pointing out that some customers are non-car owners who want to use shared cars to get… 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.
PolyPlus scores $9 million DOE grant for its battery technology
The PolyPlus lithium-water battery has achieved the highest energy density ever recorded – 1,300 Wh/kg, far more than the maximum delivered by current lithium-ion batteries.
Paris car sharing service launches with 250 EVs
Car sharing services, which allow drivers to rent vehicles for a few hours at a time, are popular in Europe’s cities. They’re a natural fit for EVs, because most users will drive only short distances, the cars can be recharged at the central pick-up/drop-off locations, and of course EVs reduce air and noise pollution in… Read more »
Ionic Mineral discovers a major trove of rare earth and critical minerals in Utah
Ionic Mineral Technologies has discovered a major high-grade deposit of rare earth minerals and critical technology metals at its fully-permitted Silicon Ridge project in Utah. The trove could prove to be a domestic source for elements used in the manufacture of EVs and many other high-tech products—elements that currently come mostly from China. Independent assays… Read more »
PEM tests feasibility of battery cells containing 80% recycled content
The Chair of Production Engineering of E-Mobility Components (PEM) at RWTH Aachen University is working with industrial partners on the Kreislauf.IN.NRW battery cell recycling research project. The project, funded by the Ministry for the Environment, Nature Conservation and Transport of the State of North Rhine-Westphalia, aims to investigate the production and functionality of cells containing… Read more »
