Researchers add MXene to silicon anodes, improving charge life

Researchers at Drexel University and Trinity College have found that using silicon fortified with a special type of materials called MXene in Li-ion anodes could improve charge-to-charge life of batteries. The group reports in Nature Communications that the latest Li-ion batteries on the market are likely to extend the charge-to-charge life of phones and EVs… Read more »

Battery metals see bigger gains in 2018 than EVs thanks to increasing battery capacity

In 2018, global deployment of nickel, graphite, copper, LCE, aluminum and cobalt by cell suppliers for passenger vehicles increased by 75% to 99% over the previous year, according to data from Adamas Intelligence’s EV Battery Capacity and Battery Metals Tracker. These growth rates are particularly remarkable considering that global EV registrations increased by just 67% over the… Read more »

Sepion receives CEC grant for composite battery membranes

The California Energy Commission (CEC) has awarded $450,000 in grant funding to Sepion Technologies, an Emeryville, California company that’s developing a composite battery membrane designed to replace ceramic components. Sepion’s composite membranes  provide high-flux and ion-selective transport, and the company says they can be processed in large-area formats at a fraction of the cost of ceramics. The project’s… Read more »

Daimler and thysenkrupp partner to develop bipolar batteries

Under a project sponsored by the German Ministry for Economic Affairs and Energy, Daimler and the Fraunhofer Institute, together with German conglomerate thyssenkrupp and engineering firm IAV, are co-developing the design and production of bipolar batteries. Bipolar batteries are still in the laboratory stage and have not moved past pilot scale. The project, named EMBATT-goes-FAB,… Read more »

Amprius’s silicon nanowire batteries power the Zephyr S HAPS solar aircraft

Battery manufacturer Amprius is supplying lithium-ion cells to Airbus’s Zephyr program. Using Amprius’s cells, which contain a 100% silicon anode, the Zephyr S solar-powered unmanned aerial vehicle (UAV) recently flew more than 25 days, setting a new record for stratospheric flight. The Zephyr S is a high-altitude pseudo-satellite (HAPS), which combines the persistence of a… Read more »

Worcester Polytechnic research team wins award from USABC for battery recycling process

An engineering research team at Worcester Polytechnic Institute (WPI) in Massachusetts recently won a million-dollar contract from the United States Advanced Battery Consortium (USABC) to develop an innovative process for recycling used Li-ion batteries. The team, led by WPI professor Yan Wang, it created a patented closed-loop recycling process that works like this: the batteries… Read more »

University of Michigan researchers develop non-combustible, non-degrading ceramic electrolyte

Scientists at the University of Michigan have developed a solid-state electrolyte which they claim is non-combustible (which is good, because it’s heated to over 1,800° F during manufacturing!) and not vulnerable to dendrite formation due to a stabilizing ceramic layer. The electrolyte has special properties that allow for increased capacities and faster charging rates as well. Current… Read more »

Penn State researchers develop cold-weather fast charging method for Li-ion batteries

Fast charging cold Li-ion batteries comes with the risk of lithium plating. When metallic lithium is formed in a battery, it can severely reduce battery lifespan and increase instability. Researchers from Penn State have suggested a solution to that problem that can provide 15-minute fast charging and a twelve-year battery lifespan in temperatures as low as… Read more »

Cambridge study reveals fast-charging potential of niobium tungsten oxides

Cambridge research has shed light on the potential of a previously ignored class of electrode material: niobium tungsten oxides. These compounds display several promising properties, including a lack of the dendrite formation which plagues graphite-based designs. They have a relatively large particle size and a structure that allows lithium ions to travel freely. This high transport rate can… Read more »

Iron trifluoride cathode could greatly increase energy density

Researchers from the University of Maryland and the DOE’s Brookhaven National Laboratory have developed a cathode material containing iron trifluoride (FeF3) that they say could triple the energy density of Li-ion batteries. Their research was published in Nature Communications. “Compared to the large capacity of the commercial graphite anodes used in lithium-ion batteries, the capacity of the cathodes is… Read more »
