Roskill: Niobium industry looking for a future beyond steel; Li-ion batteries a possibility

Green Car Congress

The winner of the best paper in 2019 was an effort by researchers then at the University of Cambridge, Argonne National Laboratory and the Diamond Light Source, Harwell Science and Innovation Campus, on the use of niobium tungsten oxides for high-rate lithium-ion battery storage. The paper (Griffith et al. ) Griffith et al.

CATL launches “condensed battery” with an energy density of up to 500 Wh/kg for aircraft; automotive version this year

Green Car Congress

The launch of this technology breaks the limits that have long restricted the development of the battery sector and will open up a new scenario of electrification centering on high level of safety and light weight, CATL said. For example, in 2021, CATL rolled out the first generation of sodium-ion battery with an energy density of 160 Wh/kg.

UMD researchers report solution to high interfacial impedance hampering developing of high-performance solid-state Li-ion batteries

Green Car Congress

Garnet-type solid-state electrolytes (SSEs) for Li-ion batteries offer a range of attractive benefits, including high ionic conductivity (approaching 1 mS cm −1 at room temperature); excellent environmental stability with processing flexibility; and a wide electrochemical stability window. With the garnet composition Li 7 La 2.75
