ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The University of Texas at Arlington will develop acoustic stimulation and electrolytic proton production to produce lithium (Li) and nickel (Ni) from CO 2 -reactive minerals and rocks that contain calcium (Ca) and magnesium (Mg), while sequestering CO 2 in the form of carbonate solids. Travertine Technologies.

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

We need new storage technologies if more renewables are to be used on the electrical grid; similarly, the electrification of transport requires much cheaper and longer-lasting batteries. Under such a scenario, the production of Li-ion batteries should expand hugely over the years to come, hence reviving the issue of finite Li reserves.

New direct borohydride fuel cell increases peak power density by factor of 1.7–3.7

Green Car Congress

A direct borohydride fuel cell—first demonstrated in the early 1960s—is a type of alkaline fuel cell directly fed by a sodium borohydride or potassium borohydride solution. Xiaodong Yang, Yongning Liu, Sai Li, Xiaozhu Wei, Li Wang & Yuanzhen Chen (2012). DBFCs feature a high open circuit voltage (1.64

High-capacity GQD-coated VO2 nanoarray electrodes for high-performance Li- and Na-ion batteries

Green Car Congress

Researchers from Nanyang Technical University (NTU) in Singapore have shown high-capacity, high-rate, and durable lithium- and sodium-ion battery (LIB and NIB) performance using single-crystalline long-range-ordered bilayered VO 2 nanoarray electrodes. This is important in boosting the high-rate performance in both Li and Na ion storage.
